## Title
Device connectivity framework

## Abstract

A system and method for providing a device agnostic framework between two or more computing platforms. The system includes a protocol for creating device agnostic messages including data from a message generated by an application on the first computing platform, as well as identification and targeting data to enable the message to be sent to the intend target computing platform. The intended target computing platform responds via a callback, thereby establishing a communication protocol between the first and second computing platforms regardless of different computing languages or hardware being used.

## Background
FIELD OF THE INVENTION
The present invention relates to a system and method for providing a multilingual computer framework for sending and receiving messages comprised of objects between different devices and/or operating systems. Specifically, the present invention includes an improved device connectivity framework, which is a system for facilitating communication between two or more software platforms without the need for common computer languages, common operating systems or even common hardware. The system and method includes the use of computerized translation data using a common protocol, the translation data being attached to a message being sent from one software platform to another software platform. This framework thus provides the ability to connect software applications that are aware of one another & can exchange data with other applications that utilize the same framework or protocol. The present invention has particular applicability in any field where there is a need for bridging a communication gap between computer applications.
BACKGROUND OF THE INVENTION
Computer applications offer a wide variety of functionality capabilities, each with their own fortes and limitations. In addition, the increase in internet connectivity (especially in mobile applications) has resulted in an increase in web based computer programs. One such class of applications are known as Rich Internet Applications, or RIAs. An RIA is a Web application that has many of the characteristics of desktop application software, typically delivered either by way of a site-specific browser, via a browser plug-in, independent sandboxes, use of JavaScript, or virtual machines. Adobe Flash, Java FX, and Microsoft Silverlight are currently the three most common platforms, with desktop browser penetration rates around 96%, 76%, and 66% respectively as of August 2011. Mobile phone penetration of these plugins, however, has remained low even as internet traffic from these devices has grown. Although new Web standards have emerged, they still use the principles behind RIAs. Users generally need to install a software framework using the computer's operating system before launching the application, which typically downloads, updates, verifies and executes the RIA.
A further problem with such software usage is the limitations of frameworks and similar mechanisms for facilitating such connections are platform dependent. For example, a given RIA cannot use the same framework to permit an application to communicate equally with a Java based application and a Flash based application. This limitation, understandably, limits the utility of RIAs and the potential they offer to users and content providers alike.
Thus, the present state of the art reflects a need for a device connectivity framework which operates with browser based access to native application code, as well as having the ability to enable such communication without regard to the software platforms involved.
DESCRIPTION OF THE PRIOR ART
One example of a prior art approach is found in Microsoft's OLE technology, as well as its successors MS ActiveX and Microsoft's .NET initiative. The .NET initiative includes Microsoft Silverlight, a graphical user interface technology that enables user-experience driven applications to run both inside and outside of the Web browser. ActiveX controls allow for browser-based HTML applications to communicate with applications running on a client computer and external resources. However, ActiveX requires the MS Internet explorer browser and the MS Windows operating system, along with client code created to run on the Windows environment.
Another prior art approach was made available by the present inventors through the Merapi Project. Merapi is a JavaTM application, intended to run on a user's (client) computer. Merapi connects other Java applications on the user's computer to Adobe AIRTM applications that the user has installed. With Merapi, the Adobe AIR application must be developed in a way that allows it to connect to Merapi. Merapi acts as a “middle man”, passing objects between a user's AIR application and a Java application. The Merapi Project is thus a software “bridge” that allows Adobe AIR (psuedo-desktop/thin-client) applications to use native code, written in Java, at runtime, on the same local machine on which the AIR application is being run. However, the Merapi Project fails to enable or suggest browser-based access to native code. Likewise, the Merapi Project fails to teach the ability to execute native code other than Java.
What is needed is a device and platform agnostic computer communication system between multiple software platforms which includes browser based access to native code.
DEFINITION OF TERMS
The following terms are used in the claims of the patent as filed and are intended to have their broadest plain and ordinary meaning consistent with the requirements of the law.
A “device agnostic message” is computerized communication data provided to an intended target which includes or is derived from at least both native data from a computer platform sending the communication as well as translation data such that the message may be processed by the intended target.
“Computerized instruction data” is a command or communication derived from an application on a first software platform which is made available to a second software platform.
“Target information” is information which identifies the intended recipient(s) of a given device agnostic message. Such information may include, but is not limited to information specifying a particular computer address and/or computer communication port.
“Translation data” is computerized information which allows processing of the computerized instruction data in a device agnostic message to be processed by a given target software platform without requiring the native application for such computerized instruction data.
Where alternative meanings are possible, the broadest meaning is intended. All words used in the claims set forth below are intended to be used in the normal, customary usage of grammar and the English language.
OBJECTS AND SUMMARY OF THE INVENTION
The apparatus and method of the present invention generally includes a computer platform agnostic device connectivity framework for enabling computer messages to flow between at least a first computer platform and a second computer platform without need for any common hardware or software applications or languages. The frame typically includes the creation of a message by a first application, the appendage or creation of a device agnostic message using the message by the first application and attaching identification and/or target data thereto, sending the device to an intended target using the identification and/or target data, and receive of a response message or callback message from the intended target acknowledging receipt of the device agnostic message.
An immediate application of one embodiment of the present invention will be seen in enabling communications from a first software platform (e.g., a desktop application such as an Adobe Flash application) to a remote, second software platform (e.g., a mobile phone application such as an Android application). However, those of skill will understand that certain objects of the present invention will similarly be met through a second embodiment wherein the first and second software platforms reside on the same device (e.g., by providing device agnostic messages through a communications port between two applications using different languages but residing on the same desktop computer).
Thus can be seen that one object of the present invention is to provide a device connectivity framework or method and system which enables communications with and instruction data being provided from a first computer platform to a second computer platform regardless of whether the two platforms employ the same applications, language or hardware.
A further object of the present invention is to provide a system and method for enabling remote communication of computer instructions between two different software platforms without requiring common software languages or applications.
Still another object of the present invention is to provide a system and method which enables the coding of computer instructions from a first application such that they can be operated upon by a recipient computer regardless of the applications native to the recipient computer.
Yet another object of the present invention is to provide a system and method whereby a web application, such as a browser, can communicate with and process instructions from a native device application on the same or a different computer regardless of the language used by the native device application.
Still another object of the present invention is to provide a system and method which enables a distributed connectivity framework architecture which uses an intermediate device (including cloud or internet connected hardware devices) to enable the passage of instructions and communications between two different applications on two different remote computing devices without requiring the same applications to reside on such computing devices.
It should be noted that not every embodiment of the claimed invention will accomplish each of the objects of the invention set forth above. In addition, further objects of the invention will become apparent based the summary of the invention, the detailed description of preferred embodiments, and as illustrated in the accompanying drawings. Such objects, features, and advantages of the present invention will become more apparent in light of the following detailed description of a best mode embodiment thereof, and as illustrated in the accompanying drawings.

DETAILED DESCRIPTION OF THE INVENTION
Set forth below is a description of what is currently believed to be the preferred embodiment or best examples of the invention claimed. Future and present alternatives and modifications to this preferred embodiment are contemplated. Any alternatives or modifications which make insubstantial changes in function, in purpose, in structure or in result are intended to be covered by the claims in this patent.
A first embodiment of the present invention is shown in FIG. 1, which addresses a situation in which there exists a need for communication between a web application and a native computer application on a single hardware device. For instance, in this embodiment, a user might wish to access a first proprietary, legacy application on a hardware device using a second software application (e.g., a web browser or other application) in order to provide a superior graphical user interface without requiring the hardware device going out to a server. In such an embodiment the device connectivity framework system occurs within the confines of a first computing device 10, such as a desktop, laptop, tablet, or handheld computer (e.g., a smartphone). Residing on the first computing device 10 are a first application 12 and a second application 14. The ability to communicate between the two applications in accord with the method and system of the present invention, i.e., without requiring a common language or without operating through an outside server, begins with the step of the first application creating a message 16, e.g., generating an instruction or communication intended for the second application. The message 16 requires the step of creating a device agnostic message 18. This device agnostic message 18 includes data 20 derived from the step of creating a message, and adds to that data a unique identifier or ID 19 that identifies the intended target of the device agnostic message, and further adds a device address 22, which in the example of this first preferred embodiment could simply be the identification of a designated communications portal (socket) which would be used for handling the device agnostic messages of the present invention.
In response to receiving the device agnostic message 18, the second application 14 would most preferably generate a callback 24 which is passed back from the second application to the first application 12. The callback, in one example of the first embodiment, could simply be verification to the first application 12 that the device agnostic message 18 had been received and would thus call or initiate further subroutines or operations in the first application 12 which would result in creation of further messages 16. Of course, those of skill would understand the present invention could use the same system and method to create messages 26 by the second application 14 which using the same device agnostic message format 18, would be processed and recognized by the first application and cause the creation of a callback 30 to the second application 14. Additionally, those of ordinary skill would understand that the framework of the present invention could be used to combine the callback 30 and create messages 26 steps to practice an embodiment within the scope of the present invention.
A second embodiment of the present invention is shown in FIG. 2, which addresses a situation in which there exists a need for communication between a web application on a first hardware device and a native computer application on a second hardware device. For instance, a user may desire the ability to have a web browser application on a first device interface with a native application (e.g., a so-called smart board application) which uses separate hardware. For example, the user may have access to a web browser displaying a web application depicting a globe and offering web tools for drawing upon the globe picture. In addition, the first computer device may have attached to it a smart board and smart board tools (e.g., a smart board pen) for marking upon the smart board. The present framework would enable the user to operate the smart board pen on the smart board to implement changes on the globe being depicted as if he or she were operating the software web tools on the web application. In the system 100 of this second embodiment, the first computing device 110 has a first application 112 (e.g., a browser) which creates a message 114 intended for a second application 122 on a second device 120. As with the first embodiment, this framework involves the first application 112 creating a message 114. The message 114 is used to provide the data 134 for a device agnostic message 130, which further includes at least a unique identifier or ID 132 and an address 136 for the second computing device 120, e.g., the IP internet address. As with the first embodiment, upon receipt of the device agnostic message 130, the second application 122 generates a callback 124 which is sent back to the first computer application. Also as with the first embodiment, the device agnostic message framework of this embodiment may be used to create messages 126 by the second application, such message 126 being sent to the first application 112 which in turn generate a callback 116 from the first application 112 to the second application 122.
FIG. 3 disclosed a variant of the second preferred embodiment which is identical to that disclosed in FIG. 2 except for the additional requirement within the composition of the device agnostic message. Specifically, in this variant of the present invention, the device agnostic message 130 further includes an intent component 138 for enabling a specific command which directs a certain action to be taken by the recipient second computer device 120. For example, the instruction may be from a first application 112 to a second computer device 120 instructing the device (or an application on the device) to turn on. In this embodiment the intent acts like an address for number of recipients or listeners listening for a specific type of message, and the messages are instructions are the ones which directs certain actions. Thus, for example, a single first application, e.g., a web application, on a first device could provide communications and instructions with a number of remote computers identifying a meeting for a particular group on a given date. In such an event, the communications could be received and processed by one or more remote computers which would act upon such communications so long as they are members of the group, and further so long as the software application recognizes the message, e.g., a calendaring application might record the date of the meeting in response to the message, but a presentation application might not recognize the message, and thus would ignore it.
As shown in FIGS. 4 and 5, examples of the first 12 and second 14 applications may be, respectively, a large native application, and a presentation application, or a web application (browser) 12 and a second web application 14. The specific choices of applications are not material to the scope of present invention, except that the first application 12 and second application do not have to use the same language or have the same instruction set to operate, and the functionality of the present invention requires some level of communication between the first and second applications such that the interaction between the two is to the benefit of the user and/or the application providers. In the example of FIG. 4, the first embodiment may be employed, for example, where the user desires to have his or her first application (a large native application) provide rich content to a second application 14 which is a presentation application. In the example of FIG. 5, by contrast, both the first and second applications 12, 14 are web browser applications. In both of these examples, the system includes a helper service 40 which, in these examples, comprises a helper application install on the computing device. The functionality of this helper service would be present in FIG. 1, but would be provided, for example, by the addition of software code into the first and second applications. The embodiments of FIGS. 4 and 5, by comparison, are particularly useful where, for example, the proprietary nature of the software makes the integration of the helper service 40 into the code of the first application 12 impractical. The function of the helper service 40 is to provide the mechanism for handling the device agnostic messages between the first and second applications. For example the HTML or AJAX code in the first application 12 communicates with an embedded shockwave flash file (.SWF) (not shown), and the helper file, in turn, communicates with local components, such as drivers to enable any control or actuation of the device which desired as a result of the communication between the first and second applications.
The system 100 of FIGS. 6 and 7 are variants and examples of FIG. 2 showing an example of the present invention in communication between a first computing device 110 and a second computing device 120. The interface of this example is enabling by the helper service 140, which passes device agnostic messages 130 between the first and second computing devices. In this example, the first application creates a device agnostic message 130 whereby the first computing device start and searches the local network for another computing device which is enabled for the helper program 140. Once communication is established based upon a device agnostic message 130, the present system enables data objects to be passed seamlessly between the first application 112 and the second application 114 through TCP communications via sockets (not shown) thus enabling what appears to the user to be a multi-screen experience (e.g., the screen display and functionality of the second computing device 114 receives and displays the screen display of the first computing device 112).
In order to help those of skill in practicing the present invention, the following source code disclosure is provided. This code corresponds to the practice of the invention shown in FIG. 6. The sample of code constitutes of the following different components:

          stillListening = true;


        }


      }


    }


//first we need to pop the type from array and then unregister


handlersMap[type].splice(handlersMap[type].indexOf(this), 1);


bridge.unRegisterMessageHandler(type);


    // if there are still handlers listening to the type,


    // don't unRegister with DCF Flex library otherwise if all


    // handlers for this type are removed, then we can unregister


    // the type from the bridge


    if ( stillListening == false )


  {


    bridge.unRegisterMessageHandler( type );


  }


}









The following code implements the JavaScript methods to initiate the socket connection from the Web Application 112 using the DCF Flex Library's external interface modules.













// connects the DCF client/ui Bridge to the DCF Flex Bridge.


function connectRADCF( port, host )


{


 try {


   // forcing the port to 12365, because the Helper Service Bridge


  is listening on that port bridge.connectDCF(“12365”, host);


 }


 catch (ex) {


 }


}


// disconnects the DCF client/ui Bridge to the native Bridge.


function disconnectRADCF( )


{


   bridge.disconnectDCF( );


}


// Performs a systemExecute via a proxy call to the DCF Flex Library.


// args are passed in as array of params


function systemExecute( args) {


   bridge.systemExecute( args );


}


// The external callback for any messages that have a type that was


registered, for any type that has been registered. The list of handlers


that have registered is looked up in handlersMap and handleMessage( )


is called on each registered handler.


function handleDCFMessage(message) {


   // The list of handlers registered for messsage.type


   var list = handlersMap[ message.type ];


   // If the list is null there's nothing to do


   if ( list != null )


   {


     // Call handleMessage( ) on each handler registered


     // for message.type


     for( i=0; i<list.length; i++ )


     {


       if ( list[ i ] != null )


       {


         list[ i ].handleMessage( message );


       }


     }


   }


}


// Maps registered message types to a list of the associated handlers


registered for the type.


var handlersMap = new Object( );


// DCF Constants


// Event type for a serialization error.


var SERIALIZE_ERROR = “serializeError”;


// Event type for a deserialization error.


var DESERIALIZE_ERROR = “deserializeError”;


// Event type for a connect failure error.


var CONNECT_FAILURE_ERROR = “connectFailureError”;


// Event type for an initialization error.


var INITIALIZATION_ERROR = “initializationError”;


var CONNECT_SUCCESS = “connectSuccess”;









In order to handle the Message 130 types for connect success and the connect failure statuses between first Web Application 112 and Helper Service 140, we have to register a MessageHandler with above types. The following javascript registers the listener message types by invoking the javascript method titled “registerListenerMessageTypesQ”:













function registerListenerMessageTypes( ) {


 try {


   // creates a new messagehandler to store these message types


  var connectHandler = new MessageHandler( );


  connectHandler.addMessageType(CONNECT_FAILURE_ERROR);


  connectHandler.addMessageType(CONNECT_SUCCESS);


   // Maps the handleMessage to the callback of this method


   // when the DCF Flex bridge triggers the


handleDCFMessage(message) through external the following


handler will get triggered


  connectHandler.handleMessage = handleStatus( );


  }


 catch (e) {


  console.log(“Error in register listener: ” + e);


 }


}

The above code may be used to implement the client DCF Flex Bridge, which enables the connection between Web Application 112 and Helper Service 140. When the JavaScript from the HTML DOM executes connectRADCF part of Web Application 112 that invokes bridge.connectDCF method of DCF Flex Library part of Web Application 112 which is available through actionscript's externalinterface. Now the DCF Flex Library part of Web Application 112 establishes a socket connection on the specified port with the DCF C# Library part of Helper Service 140. Once the connection is successfully established between the Web Application 112 and the Helper Service 140, the Web Application 112 proceeds with further work flow process depends on the requirements that application needs to satisfy.

The following code is customized to the workflow process or requirements or intended purpose of the figures attached. The following workflow process tracks along with FIG. 6, the purpose of which is to allow a Web Application 112 running on a first computing device 110 with Helper Service 140 installed to communicate to a second computing device 120, which in this example is an android device.
Step 1: Message Creation 114 by Web Application 112 on Computing Device 110
Before the step of Message Creation 114 in this example, Web Application 112 registers required Message Types with the DCF Flex Bridge Instance part of Web Application 112 using the MessageHandler's AddMessageType illustrated in the JavaScript MessageHandler Prototype implementation.












//code to register the Message Types for this process


function registerRaVtDeviceInterpreterMessageTypes( ) {


 var connectHandler = new MessageHandler( );


 connectHandler.-


 addMessageType(RaVt_INTERPRETER_MESSAGE_HANDLER);


 connectHandler.handleMessage = responsefromDevice(message);


}









The next step is Message Creation 114. The following code creates the message 130 to request to connect to external Android device 120 and sends that to the Android Device 120 through the established connection between Web Application 112 and Helper Service 140.












function sendMessage( ) {


//message (130)


 var message = new Message( );


//specifies the registerd message type, which in this case acts as target


 message.type (136) =


 RaVt_INTERPRETER_MESSAGE_HANDLER;


//specifies the data object or string or constant or any arbitrary value


Var Data =


‘{“Command”:“DEVICE_CONNECT_REQUEST”,


“Mode”:“REQUEST”,“Count”:1,“HasData”:


true,“Data”:{“Serial”:“015D941A0B01E02B”,


“Path”:“C:\\ProgramData\\RaVt\\Install\\RaVtAndroid


Support.apk”},“HasError”:false,“Error”:{ }}’;


 message.data (134) = Data;


//invokes the javascript prototype send method illustrated below


 message.send( );


//message id (132) is auto-generated in the DCF Flex library


}


//The following method invokes the DCF Flex library sendMessage


through external interface Message.prototype.send = function( )


{


   bridge.sendMessage( this );


}


//DCF Flex Library sendMessage implementation which serializes the


message using AMF and writes the message on the socket


public function sendMessage( message : IMessage, responder :


IResponder=null ) : void


 {


  // Try to serialize the message using AMF _writer.


   var bytes : ByteArray = _writer.write( message );


  // Write the message on the socket and flush the packets.


   _client.writeBytes( bytes );


   _client.flush( );


 }


//DCF C# Library's BridgeListenerThread reads data from the input


stream of the accepted client socket connection as below and dispatches


the message using Bridge Instance DispatchMessage as illustrated below


public void Run( )


{


// reads all the bytes from the input stream, check the illustrated for details,


uses the AMF reader


_reader.read(bytes);


// Broadcast the Message from the Bridge


 Bridge.GetInstance( ).DispatchMessage( message );


}


public void DispatchMessage( IMessage message )


{


// Checks to see if there is any handlers registered by helper services for


this message type


“RaVt_INTERPRETER_MESSAGE_HANDLER”


   if ( _handlers.ContainsKey(message.type) == false )


   {


    return;


   }


   else


   {


// if it finds list of handlers for this message type then it invokes each


handler's HandleMessage which is overrided in the


ListenerMessageHandler


    list = _handlers[message.type];


    if ((list != null) && (list.Count >> 0))


    {


     foreach (IMessageHandler handler in list)


     {


      handler.HandleMessage(message);


     }


    }


    }


}


//DCF C# Helper Service's ListenerMessageHandler handles the


message type using the overridden HandleMessage Method.


public ListenerMessageHandler( )


{


AddMessageType(RaVt_INTERPRETER_MESSAGE_HANDLER);


}


//handling the message type to fulfill the requirements or workflow process


public override void HandleMessage( IMessage message )


{


if ( message.type.-


Equals(RaVt_INTERPRETER_MESSAGE_HANDLER) )


  {


      //customized method to do the required actions or execution


   HandleInterPreterMessage(message);


  }


}









As enabled by the code shown above, the device agnostic message 130 created by the Web Application 112 has now reached Helper Service 140. The Helper Service 140 now passes the device agnostic message 130 to Android Device 120, which contains the native android application 122.
In order to send the message to the android device 120, a device interpreter class part of Helper Service 140 is implemented, which can be a customized class for any action that needed to fulfill the device agnostic message 130.












//Implementation of a wrapper class for DeviceInterpreter API


class RaVtDeviceInterpreterWrapper


{


   //deviceinterpreter API class


  private DeviceInterpreter deviceInterpreter = null;


   //deviceinterpreterlistener class


  private DeviceInterpreterListener deviceInterpreterListener = null;


  public RaVtDeviceInterpreterWrapper( )


  {


   deviceInterpreterListener = new DeviceInterpreterListener( );


    deviceInterpreter = new


    DeviceInterpreter(deviceInterpreterListener);


    deviceInterpreter.initialize(deviceDetails.ToString( ));


  }


   // sends the message to the device using the deviceInterpreter API


  public void sendClientMessageToADB(string jsondata)


  {


   deviceInterpreter.sendRequest(RequestID, jsondata);


  }


 }









The following code receives the response message 126 or callback 124 from the Android Device 120 which is then packaged as device agnostic message 130 and sent back to the web Application 112 from the Helper Service 140 using the established socket connection.












//Device Interpreter Listener class responsible to handle the callback from


the device which sends messages or responses back through device


interpreter


 public class DeviceInterpreterListener : IDeviceInterpreter


 {


   // handles the Message or Callback from Android Application (122)


  public void MessageCallback(string responseid, string responsemsg)


  {


     //message (126) generated from android application(122)


part of the Android device (120)


   Message m = new Message( );


     //type which acts as target


   m.type = RaVt_INTERPRETER_MESSAGE_HANDLER;


     //response data back to web application


   m.data = respmsg;


     //send invokes the DCF C# library's send method


of the Message class illustrated earlier


   m.send( );


  }


 }


//Message class send method


public void send( )


{


   //invokes the bridge sendMessage to send the message across the


bridge through the socket connection


   Bridge.GetInstance( ).SendMessage( this );


}


//following method part of DCF C# library Bridge.cs class


public void SendMessage( IMessage message )


  {


     // Serializes the message using AMT Writer


       byte[ ] bytes = _writer.write( message );


   // Send the length of the message first


   byte[ ] lenBytes = new byte[4];


   lenBytes[0] = (byte)(bytes.Length >> 24);


   lenBytes[1] = (byte)(bytes.Length >> 16);


   lenBytes[2] = (byte)(bytes.Length >> 8);


   lenBytes[3] = (byte)bytes.Length;


   //send the header


   _client.Send(lenBytes);


   _client.Send(bytes);


    }


//DCF Flex Library handleReciveSocketData reads all the input stream


private function handleReceiveSocketData( event : ProgressEvent ) : void


{


   var messages : Array = _reader.read( _byteBuffer ).reverse( );


// decodes the message to of type Message (130).


   var message : IMessage = null;


   var decoded : Object = messages.pop( );


   message = decoded as IMessage;


// Dispatchs the message to registered IMessageHandlers


   dispatchMessage( message );


}









The following code dispatches the message from DCF C# Library part of Helper Service 140 to the JavaScript part of the Web Application 112 using the handleDCFMessage externalinterface implementation.












public function dispatchMessage( message : IMessage ) : void


{


// Get the list of handlers registered for the


RaVt_INTERPRETER_MESSAGE_HANDLER


message type


  var list : Array = _handlers[ message.type ] as Array;


  // invokes the handleMessage of the registered Messagehandlers


  handler.handleMessage( message );


}


// The handleMessage class invokes the overrided method of the


JavaScriptHandler class.


override public function handleMessage( message : IMessage ) : void


{


//invokes the handleDCFMessage JavaScript method part of the


web application.


ExternalInterface.call( “handleDCFMessage”, message );


}









The handleDCFMessage method of the Web Application 112 as illustrated below invokes the respective handler methods or actions mapped to handlersMap array part of javascript implementation part of Web Application 112 based on the message target 136.












function handleDCFMessage(message) {


  // The list of handlers registered for messsage.type


  var list = handlersMap[ message.type ];


  // since we have the connectHandler registered for this message type


  //it invokes the connectHandler handleMessage which invokes the responsefromdevice( )


  connectHandler.handleMessage( message );


}


function responsefromDevice(message) {


  // the message (126) from the device reached the web application using the DCF bridge


//specifies the data object or string or constant or any arbitrary value


 Var Respmsg = message.data (134);


  //sample response message


Respmsg:


“{“Command”:“DEVICE_CONNECT_REQUEST”,“Data”:{ “Serial” :“015D941A0B01E02B”,“


Approved”:true,“Path”:“C:\\ProgramData\\RaVt\\Install\\RaVtAndroidSupport.apk”},“HasData”:


true,“Count”:1,“HasError”:false,“Mode”:“RESPONSE”}”


}









Thus, this example code demonstrates how a device agnostic message 130 begun by creating a message 114 from Web Application 112 on the first computing device 110 through the use of the Helper Service 140, the message 130 then being passed to the android device 120 containing the native android application 122. The android application 122 can execute instructions based upon the data of the message, and further respond by creating a message 126 or callback 124 with instructions to Web Application 112.

A further variant of the present invention is shown in FIG. 8. In this preferred embodiment, the communication system 200 of the preset invention comprises a first computing device 210, a second computing device 220 and a third, intermediary computing device 230. In this embodiment of the present invention, the intermediary computing device 230 could comprise a cloud based device communications framework which enables communication between the first computing device 210 and the second computing device. For instance, the address component 236 of an initial device agnostic message from a first computing device (e.g., a desktop) to a second computing device (e.g., a smartphone) might lack the socket address of the second computing device and instead have only the phone number of the target smartphone, but the cloud computing intermediary computing device could use, for instance, a database (not shown) to look up the IP address of the smart phone to facilitate the ongoing communication and control abilities as described above. Likewise, the features of certain other embodiments could be combined within the bounds of this embodiment. For instance, the use of intent 236 could be employed to permit a first device to send out communications which would be interpreted and acted upon only by a subset of applications from a group of remote mobile computing devices such as second computing device 220. A specific embodiment of this implementation is where a multiple users walk into a store, and the store operator is periodically generating generic messages to be received and acted upon by responsive mobile computing devices, e.g., a phone store polling phones for diagnostic information of customers coming into the store to permit better support.
