DETAILED DESCRIPTION
The market for mobile applications is rapidly growing, but the ability to identify and correct performance issues of an application has lagged behind. As the number and variety of applications available in the market increase, so has the likelihood that an application may experience performance issues when run in conjunction with other applications and/or when utilizing multiple functions/sensors of a mobile device. In particular, determining the cause of an application performance issue may make it possible to help fix the cause of the performance issue and/or take action to alleviate user dissatisfaction.
An application provider may monitor the performance of applications by gathering performance criteria data such as a list of other applications that are installed on a user's device when a performance issue arises with a poorly performing application, a list of other applications that are running on a user's device at the time a performance issue arises with a poorly performing application, how often an application is run on a device, how long the application is the primary item displayed on the device screen, the degree of interaction (e.g., the frequency and number of different inputs to device sensors such as touch, tilt, shake, and the like) when an application is running on a device, and the like.
Specifically, some applications may experience performance issues caused by resource utilization events such as when running simultaneously with other applications, when using multiple functions of a device, and/or when using multiple sensors on a device. An application may experience performance issues when running simultaneously or in conjunction with other applications. For example, a weather application may experience performance issues when running in combination with specific stock ticker and city guide applications. Further, application data permissions may be different for applications running simultaneously, for example, a photo editing application and a social networking application may be running simultaneously and each may be attempting to use the mobile device's camera function at the same time, resulting in either one or both applications failing and/or crashing. Additionally, an application may experience performance issues because of an overload associated with resources being used while running the application. For example, a gaming application may use multiple sensors on a device, such as a touch screen, an accelerometer, and a tilt sensor. The gaming application may crash and/or have performance issues based on an overload caused by simultaneous use of these multiple sensors.
For example, a device operating system may receive performance criteria for an application such as crash reports, activity not responding reports, battery reports, running services reports, user initiated feedback reports, network reports, and the like. The device operating system may provide these performance criteria to an application provider. A system may evaluate and monitor this performance information to determine if there have been any changes in the performance of the application. If there has been an increase in the number or severity of performance issues relating to a specific version of the application, the application provider may evaluate the performance criteria and determine that the performance issue is caused by a resource utilization event. As a result, an action may be taken to correct the performance issue and/or alleviate user dissatisfaction with the poorly performing application.
The present disclosure proposes a method for automatically identifying a particular application and/or a particular version of an application that is experiencing performance problems caused by a resource utilization event. A resource utilization event may include two or more applications running simultaneously, two or more applications using one or more device functions at the same time, and/or an overload based on simultaneous use of multiple device sensors.
A device may be a mobile device, a smartphone, a laptop, a tablet, a PC, a wearable computer, an appliance, and any other device capable of running an application. Various devices may perform and/or include multiple functions. For example, functions of a device may include camera, battery, touchscreen, keyboard, display, memory, Bluetooth, media player, location service, cellular network service, Internet service, messaging service, voice command service, streaming content service, and the like. A variety of sensors may also be included on a device such as touchscreen, accelerometer, tilt, rotation, gyroscope, orientation, digital compass, barometer, microphone, camera, ambient light, proximity, ambient temperature, gravity, motion, GPS, radiation, and the like.
FIG. 1 shows an example process according to an implementation of the disclosed subject matter. As shown in FIG. 1, a method may include receiving an indication that a first application is experiencing a performance issue, at 101. It may be determined that the performance issue is caused by a resource utilization event on a device, at 102. A resource utilization event may be one or more of the following: an application and one or more other applications running simultaneously, use of one or more functions of the device simultaneously by at least one of the first application and one or more other applications, and/or a resource utilization overload based on simultaneous use of a plurality of sensors on the device. Next, action may be taken to correct the performance issue of the first application, at 103.
A performance issue may be any issue relating to the performance of an application caused by a resource utilization event. Examples of a performance issue may include a run time error, an application failure, an application crash, an activity not responding error, a user-initiated negative feedback, a poor battery usage report, a processing delay, a processing error, a trapped error, and the like.
As an example, performance criteria may be received from devices running version 6 of a social network application. The performance criteria may include crash reports, data indicating other applications running at the same time as version 6 of the social network application during the crash reports, and user-initiated feedback reports from the devices. Based on the criteria, it may be determined that version 6 of the social network application is crashing due to a resource utilization event, in particular while running simultaneously with version 2 of a weather application. Accordingly, an application may take action to correct this performance issue, for example, by notifying the application developers of version 6 of the social network application and version 2 of the weather application of the performance issue.
According to an implementation, a system may include a processor configured to receive an indication that a first application is experiencing a performance issue. It may be determined that the performance issue is caused by a resource utilization event on a device. As discussed above, a resource utilization event may be the first application and one or more other applications running simultaneously, use of one or more functions of the device simultaneously by the first application, or the first application and one or more other applications, and/or a resource utilization overload based on simultaneous use of a plurality of sensors on the device. Next, action may be taken to correct the performance issue of the first application.
FIG. 2 shows an example information flow according to an implementation of the disclosed subject matter. An application provider may receive an indication that an application is experiencing a performance issue from one or more devices, at 201. The application provider may determine that the performance issue is caused by a resource utilization event, at 202. Next, the application provider may take action to correct the performance issue of the application.
In general, several actions may be taken to correct the performance issue of an application. These various actions may be taken automatically by a system that provides, stores, or executes the applications, as described in further detail below. A device may take corrective action automatically, such as by upgrading, downgrading, or suspending execution of one or both of the applications. For example, a device may reallocate resources, prioritize the use of resources by applications, implement a delay for use of a function by an application, implement a delay for use of a sensor by an application, and the like. Further, an application provider may stop providing the application to users, notify the application developer of the cause of the performance problem, refund the cost of the application to a user, issue an application store credit to a user, and the like. For example, where the applications are installed on a mobile computing device such as a smartphone, the device may automatically provide a notification to a user or a developer that there is a conflict between the applications, by identifying the performance issue and one or both of the applications, or the like. Additionally, an application provider may pause sales of the application to users, notify users that the application may be available soon, warn a user that the application may not work on his hardware, and/or notify a user of the version of the OS on which the application will work.
In an implementation, upon identifying that an application is experiencing a performance issue caused by a resource utilization event, an action to correct the performance issue of the application may be taken by an application provider, an application developer, and/or a device. For example, taking action to correct the performance issue of an application may include notifying a user who previously downloaded the application of the performance issue, and performing one or more actions including automatically removing the first application from the user's device, automatically providing a refund to the user, and/or automatically providing an updated version of the first application to the user. The updated version may correct the performance issue.
In some instances, an application may experience performance issues because of an overload associated with resources being used while running the application. For example, a gaming application may use multiple sensors on a device, such as a touch screen, an accelerometer, and a tilt sensor. The gaming application may crash and/or have performance issues based on an overload caused by simultaneous use of these multiple sensors. The application may not be able to process the data received from the multiple sensors at the rate the sensors provide data, leading to a failure of the application or other performance issue. As another example, the application may receive sensor data at a rate exceeding the storage space allocated for the data by the application, leading to a failure or other performance issue. As a result, an application provider may take action to correct the performance issue such as notify users who previously downloaded the gaming application of the performance issue, removing the gaming application from devices, and/or providing a refund to all users who previously downloaded the gaming application. Additionally, it may be the case that the gaming application is experiencing this performance issue while running on devices with OS version 1.0 and not with OS version 2.0. In this case, the application provider may notify users with OS version 1.0 of the performance issue associated with the gaming application, and recommend that users of OS version 1.0 upgrade to OS version 2.0 to correct the performance issue. In some instances, the upgraded OS version 2.0 may not be available on a user's device based on a restriction imposed by his particular wireless carrier. In this case, the application provider may notify the user that OS version 2.0 may correct the performance issue associated with the gaming application but that his particular wireless carrier is not currently supporting the upgrade.
Taking action to correct the performance issue of an application may also include notifying an application provider of the performance issue. In this case, an updated version of the application may be received and the updated version may correct the performance issue. Additionally, the updated version of the application may be provided to a user who previously downloaded the application. In some instances, an application provider may automatically provide a refund to a user who previously purchased the application.
Additionally, taking action to correct the performance issue of an application may include notifying an application developer of the performance issue. In this case, an updated version of the application may be received and the updated version may correct the performance issue. This updated version of the application may be provided to an application provider. For example, an application provider may receive performance criteria indicating that a weather application is crashing when running in combination with a specific stock ticker and city guide applications. As a result, several actions may be taken. One action may be that the application provider notifies the application developer of the weather application of the performance issue caused while running in combination with the stock ticker and city guide applications. The application developer may correct the performance issue with a new version of the weather application, which may be provided to the application provider. The application provider may provide this new version of the weather application to all users who previously downloaded the weather application or to only those users who previously downloaded the weather, stock ticker, and city guide applications.
Other actions may be taken to correct the performance issue of an application. For example, preventing the application from running simultaneously with one or more other applications, prioritizing use of the one or more functions of the device by the application or between the application and one or more other applications, prioritizing use of a sensor from among multiple sensors by the application, implementing a delay for use of the one or more functions between the application and one or more other applications, implementing a delay for use of a sensor from among multiple sensors by the application, and the like. Additionally, application data permissions may be different for particular applications running simultaneously. For example, a photo editing application and a social networking application may be running simultaneously and each may be attempting to use a mobile device's camera function at the same time, resulting in either one or both applications failing and/or crashing. As a result, a device may take several actions such as preventing the social networking application from running simultaneously with the photo editing application, prioritizing use of the camera function by the photo editing application over the social networking application, implementing a delay for use of the camera function by the social networking application while the photo editing application is running, and the like.
In some instances, a particular demographic of users may be experiencing a performance issue associated with an application which is caused by a resource utilization event. In this case, an action to correct the performance issue may be targeted to the particular demographic. For example, a gaming application may be experiencing performance issues only when running on “Smartphone 3” devices (i.e., a particular brand and/or hardware model device) but not on other device types. An action to correct this performance issue may be taken only with regard to Smartphone 3 devices. A demographic may refer to any segment of the population running an application and may refer to a device, a device manufacturer, OS version, locale, carrier, cellular standard, geographic region, and any other demographic having the at least one performance issue. For example, a demographic may be based on the particular device running an application such as Smartphone 4 devices, a specific brand of devices, the OS version on the device and/or any other device characteristic that may affect application performance. As another example, a demographic may be based on a specific wireless carrier of a device and/or a cellular standard offered by a wireless carrier, such as, CDMA, GSM, 3G, 4G, 4G LTE, and the like. A demographic may also be based on the locale and/or geographic region associated with a device and/or user. For example, a locale or geographic region may refer to a zip code, area code, city, county, state, country, continent, and/or a region of the world. Further, a demographic may include any combination of the above-described characteristics of a device, a carrier, and location and may further include any other characteristics that may affect application performance.
In an implementation, the communication between devices and an application provider may be across one or more bridges between the interfaces. For example, the communications between the devices and the application provider may be managed or assisted by a third device, such as a coordinating device, a local coordinator, a remote server, etc. In such cases, the third device may, for example, receive an indication that an application is experiencing a performance issue and determine that the performance issue is caused by a resource utilization event on a device. The third device may then provide the performance issue and the resource utilization event to the application provider, in which case, the application provider may take action to correct the performance issue. Alternatively, the third device may receive performance criteria from one or more devices and provide an indication that an application is experiencing a performance issue to the application provider. The application provider may determine that the performance issue is caused by a resource utilization event on a device. Accordingly, the application provider may take action to correct the performance issue. In an embodiment, the third device may also act as a bridge between the application provider and the devices when taking action to correct the performance issue. Furthermore, more than one intermediate device may be implemented to facilitate communication between devices and an application provider.
Although described in the examples above as being taken with respect to a single application, it will be clear to one of skill in the art that techniques for identifying and/or correcting performance issues may apply equally to multiple applications sequentially or concurrently. For example, in a case where a performance issue arises due to execution of two applications on a single device, the developer of each application may be notified of the performance issue. Similarly, where an action is taken to correct the performance issue, such as providing an updated version of an application, the same or different actions may be performed for each application. As a specific example, where a performance issue is identified due to a weather application and a GPS mapping application being installed or executing on a single device, an updated version of the weather application and an updated version of the GPS mapping application may be provided to the device, to an application provider, or the like as previously described. Similarly, different actions may be taken for each application based upon the other factors disclosed herein.
