## Installation

Using npm:

```shell
npm install --save react-native-device-info
```

or using yarn:

```shell
yarn add react-native-device-info
```

> ⚠️ As of version 2.1.1 the package can be loaded async to improve start up time on Android [Refer to this PR for more information](https://github.com/react-native-community/react-native-device-info/pull/680)
```java
    @Override
    public List<ReactPackage> createAdditionalReactPackages() {
        return Arrays.<ReactPackage>asList(
            new RNDeviceInfo(true), // Pass true to load the constants asynchronously on start up, default is false
        );
    }
```

> ⚠️ If you are on React Native > 0.47, you must use version 0.11.0 of this library or higher

## Linking

### Automatic

```shell
react-native link react-native-device-info
```
(or using [`rnpm`](https://github.com/rnpm/rnpm) for versions of React Native < 0.27)

```shell
rnpm link react-native-device-info
```
*For iOS users using Pods*
You still need to run `pod install` after running the above link command inside your `IOS` folder.

### Manual

<details>
    <summary>iOS (via CocoaPods)</summary>

Add the following lines to your build targets in your `Podfile`

```
pod 'React', :path => '../node_modules/react-native'

# Explicitly include Yoga if you are using RN >= 0.42.0
pod 'yoga', :path => '../node_modules/react-native/ReactCommon/yoga'

pod 'RNDeviceInfo', :path => '../node_modules/react-native-device-info'
  
# React-Native is not great about React double-including from the Podfile
post_install do |installer|
  installer.pods_project.targets.each do |target|
    if target.name == "React"
      target.remove_from_project
    end

    # It removes React & Yoga from the Pods project, as it is already included in the main project.
    targets_to_ignore = %w(React yoga)
    if targets_to_ignore.include? target.name
      target.remove_from_project
    end
  end
end
```

Then run `pod install`

</details>

<details>
    <summary>iOS (without CocoaPods)</summary>

In XCode, in the project navigator:

* Right click _Libraries_
* Add Files to _[your project's name]_
* Go to `node_modules/react-native-device-info/ios`
* Add the file `RNDeviceInfo.xcodeproj`

In XCode, in the project navigator, select your project.

* Add the `libRNDeviceInfo.a` from the _deviceinfo_ project to your project's _Build Phases ➜ Link Binary With Libraries_
* Click `.xcodeproj` file you added before in the project navigator and go the _Build Settings_ tab. Make sure _All_ is toggled on (instead of _Basic_).
* Look for _Header Search Paths_ and make sure it contains both `$(SRCROOT)/../react-native/React` and `$(SRCROOT)/../../React`
* Mark both as recursive (should be OK by default).

Run your project (Cmd+R)

<details>
    <summary>Android</summary>

* **_optional_** in `android/build.gradle`:

```gradle
...
  ext {
    // dependency versions
    googlePlayServicesVersion = "<Your play services version>" // default: "+"
    compileSdkVersion = "<Your compile SDK version>" // default: 23
    buildToolsVersion = "<Your build tools version>" // default: "25.0.2"
    targetSdkVersion = "<Your target SDK version>" // default: 22
  }
...
```

* in `android/app/build.gradle`:

```diff
dependencies {
    ...
    implementation "com.facebook.react:react-native:+"  // From node_modules
+   implementation project(':react-native-device-info')
}
```

* in `android/settings.gradle`:

```diff
...
include ':app'
+ include ':react-native-device-info'
+ project(':react-native-device-info').projectDir = new File(rootProject.projectDir, '../node_modules/react-native-device-info/android')
```

#### With React Native 0.29+

* in `MainApplication.java`:

```diff
+ import com.learnium.RNDeviceInfo.RNDeviceInfo;

  public class MainApplication extends Application implements ReactApplication {
    //......

    @Override
    protected List<ReactPackage> getPackages() {
      return Arrays.<ReactPackage>asList(
+         new RNDeviceInfo(),
          new MainReactPackage()
      );
    }

    ......
  }
```

#### With older versions of React Native:

* in `MainActivity.java`:

```diff
+ import com.learnium.RNDeviceInfo.RNDeviceInfo;

  public class MainActivity extends ReactActivity {
    ......

    @Override
    protected List<ReactPackage> getPackages() {
      return Arrays.<ReactPackage>asList(
+       new RNDeviceInfo(),
        new MainReactPackage()
      );
    }
  }
```

NOTE: If you faced with this error: `Could not resolve all files for configuration ':react-native-device-info:debugCompileClasspath'.`, in `build.gradle` put `google()` in the first line (according to https://stackoverflow.com/a/50748249)

* in `android/build.gradle`:

```diff
allprojects {
    repositories {
+       google()
        ...
    }
}
```

    <summary>Windows</summary>

* Open the solution in Visual Studio for your Windows apps
* right click your in the Explorer and click Add > Existing Project...
* Navigate to `./<app-name>/node_modules/react-native-device-info/windows/RNDeviceInfo` and add `RNDeviceInfo.csproj`
* this time right click on your React Native Windows app under your solutions directory and click Add > Reference...
* check the `RNDeviceInfo` you just added and press ok
* open up `MainReactNativeHost.cs` for your app and edit the file like so:

```diff
+ using RNDeviceInfo;
......
        protected override List<IReactPackage> Packages => new List<IReactPackage>
        {
            new MainReactPackage(),
+           new RNDeviceInfoPackage(),
        };
```

### getAPILevel()

Gets the API level.

**Examples**

```js
const apiLevel = DeviceInfo.getAPILevel();

// iOS: ?
// Android: 25
// Windows: ?
```

**Notes**

> See [API Levels](https://developer.android.com/guide/topics/manifest/uses-sdk-element.html#ApiLevels)

---

### getApplicationName()

Gets the application name.

**Examples**

```js
const appName = DeviceInfo.getApplicationName(); // "Learnium Mobile"
```

---

### getBatteryLevel()

Gets the battery level of the device as a float comprised between 0 and 1.

**Examples**

```js
DeviceInfo.getBatteryLevel().then(batteryLevel => {
  // 0.759999
});
```

**Notes**

> To be able to get actual battery level enable battery monitoring mode for application.
> Add this code:

```objective-c
[UIDevice currentDevice].batteryMonitoringEnabled = true;
```

> to AppDelegate.m application:didFinishLaunchingWithOptions:
>
> Returns -1 on the iOS Simulator

---

### getBrand()

Gets the device brand.

**Examples**

```js
const brand = DeviceInfo.getBrand();

// iOS: "Apple"
// Android: "Xiaomi"
// Windows: ?
```

---

### getBuildNumber()

Gets the application build number.

**Examples**

```js
const buildNumber = DeviceInfo.getBuildNumber();

// iOS: "89"
// Android: 4
// Windows: ?
```

**Notes**

> There is a type inconsistency: Android return an integer instead of the documented string.

---

### getBundleId()

Gets the application bundle identifier.

**Examples**

```js
const bundleId = DeviceInfo.getBundleId(); // "com.learnium.mobile"
```

---

### getCameraPresence()

Tells if the device have any camera now. 

**Examples**

```js
DeviceInfo.getCameraPresence()
  .then(isCameraPresent => {
    // true or false
  })
  .catch(cameraAccessException => {
    // is thrown if a camera device could not be queried or opened by the CameraManager on Android
  });
```

**Notes**

> * Hot add/remove of camera is supported.
> * Returns the status of the physical presence of the camera. If camera present but your app don't have permissions to use it, getCameraPresence will still return the true

---

### getCarrier()

Gets the carrier name (network operator).

**Examples**

```js
const carrier = DeviceInfo.getCarrier(); // "SOFTBANK"
```

---

### getDeviceCountry()

Gets the device country based on the locale information.

**Examples**

```js
const deviceCountry = DeviceInfo.getDeviceCountry(); // "US"
```

---

### getDeviceId()

Gets the device ID.

**Examples**

```js
const deviceId = DeviceInfo.getDeviceId();

// iOS: "iPhone7,2"
// Android: "goldfish"
// Windows: ?
```

---

### getDeviceLocale()

Gets the device locale.

**Examples**

```js
const deviceLocale = DeviceInfo.getDeviceLocale();

// iOS: "en"
// Android: "en-US"
// Windows: ?
```

---

### getPreferredLocales()

Gets the preferred locales defined by the user.

**Examples**

```js
const preferredLocales = DeviceInfo.getPreferredLocales();

// iOS: "[es-ES, en-US]"
// Android: "[es-ES, en-US]"
// Windows: ?
```

---

### getDeviceName()

Gets the device name.

**Examples**

```js
const deviceName = DeviceInfo.getDeviceName();

// iOS: "Becca's iPhone 6"
// Android: ?
// Windows: ?
```

**Android Permissions**

* [android.permission.BLUETOOTH](https://developer.android.com/reference/android/Manifest.permission.html#BLUETOOTH)

---

### getFirstInstallTime()

Gets the time at which the app was first installed, in milliseconds.

**Examples**

```js
const firstInstallTime = DeviceInfo.getFirstInstallTime();

// Android: 1517681764528
```

---

### getFontScale()

Gets the device font scale.
The font scale is the ratio of the current system font to the "normal" font size, so if normal text is 10pt and the system font is currently 15pt, the font scale would be 1.5
This can be used to determine if accessability settings has been changed for the device; you may want to re-layout certain views if the font scale is significantly larger ( > 2.0 )

In iOS App Extensions this call always returns 1.0, see #625.

**Examples**

```js
const fontScale = DeviceInfo.getFontScale(); // 1.2
```

---

### getFreeDiskStorage()

Gets available storage size, in bytes.

**Examples**

const freeDiskStorage = DeviceInfo.getFreeDiskStorage();

// Android: 17179869184
// iOS: 17179869184
```

**Notes**

> From [developer.android.com](<https://developer.android.com/reference/android/os/Environment.html#getExternalStorageDirectory()>):
>
> Return the primary shared/external storage directory.
>
> Note: don't be confused by the word "external" here. This directory can better be thought as
> media/shared storage. It is a filesystem that can hold a relatively large amount of data and
> that is shared across all applications (does not enforce permissions). Traditionally this is
> an SD card, but it may also be implemented as built-in storage in a device that is distinct
> from the protected internal storage and can be mounted as a filesystem on a computer.

## Troubleshooting

When installing or using `react-native-device-info`, you may encounter the following problems:

<details>
  <summary>[android] - Unable to merge dex / Multiple dex files / Problems with `com.google.android.gms`</summary>

`react-native-device-info` uses `com.google.android.gms:play-services-gcm` to provide [getInstance()][#getinstance].
This can lead to conflicts when building the Android application.

If you're using a different version of `com.google.android.gms:play-services-gcm` in your app, you can define the
`googlePlayServicesVersion` gradle variable in your `build.gradle` file to tell `react-native-device-info` what version
it should require. See the example project included here for a sample.

If you're using a different library that conflicts with `com.google.android.gms:play-services-gcm`, and you are certain you know what you are doing such that you will avoid version conflicts, you can simply
ignore this dependency in your gradle file:

```groovy
 compile(project(':react-native-device-info')) {
    exclude group: 'com.google.android.gms'
}
```

</details>

<details>
  <summary>[ios] - ld: library not found for -lRNDeviceInfo-tvOS</summary>

Seems to be a bug caused by `react-native link`. You can manually delete `libRNDeviceInfo-tvOS.a` in `Xcode -> [Your iOS build target] -> Build Phrases -> Link Binary with Libraries`.

</details>

<details>
  <summary>[ios] - [NetworkInfo] Descriptors query returned error: Error Domain=NSCocoaErrorDomain Code=4099
 “The connection to service named com.apple.commcenter.coretelephony.xpc was invalidated.”</summary>

This is a system level log that may be turned off by executing:
```xcrun simctl spawn booted log config --mode "level:off"  --subsystem com.apple.CoreTelephony```.
To undo the command, you can execute:
```xcrun simctl spawn booted log config --mode "level:info"  --subsystem com.apple.CoreTelephony```

</details>

<details>
  <summary>[ios] - Multiple versions of React when using CocoaPods
  "tries to require 'react-native' but there are several files providing this module"</summary>

#### You may need to adjust your Podfile like this if you use Cocoapods and have undefined symbols or duplicate React definitions

```ruby
target 'yourTargetName' do
  # See http://facebook.github.io/react-native/docs/integration-with-existing-apps.html#configuring-cocoapods-dependencies
  pod 'React', :path => '../node_modules/react-native', :subspecs => [
    'Core',
    'CxxBridge', # Include this for RN >= 0.47
    'DevSupport', # Include this to enable In-App Devmenu if RN >= 0.43
    'RCTText',
    'RCTNetwork',
    'RCTWebSocket', # Needed for debugging
    'RCTAnimation', # Needed for FlatList and animations running on native UI thread
    # Add any other subspecs you want to use in your project
  ]

  # Explicitly include Yoga if you are using RN >= 0.42.0
  pod 'yoga', :path => '../node_modules/react-native/ReactCommon/yoga'

  # Third party deps podspec link - you may have multiple pods here, just an example
  pod 'RNDeviceInfo', path: '../node_modules/react-native-device-info'

end

# if you see errors about React duplicate definitions, this fixes it. The same works for yoga.
post_install do |installer|
  installer.pods_project.targets.each do |target|
    if target.name == "React"
      target.remove_from_project
    end
  end
end
```

</details>

<details>
  <summary>[tests] - Cannot run my test suite when using this library</summary>

`react-native-device-info` contains native code, and needs to be mocked. Jest Snapshot support may work though.

Here's how to do it with jest for example:

```
// in your package.json:
"jest": {
  "setupFiles": [
    "./testenv.js"
  ],


// testenv.js:
jest.mock('react-native-device-info', () => {
  return {
    getModel: jest.fn(),
  };
});
```

</details>
<details>
    <summary>[warnings] - I get too many warnings (battery state, etc)</summary>
    
Some of the APIs (like getBatteryState) will throw warnings in certain conditions like on tvOS or the iOS emulator. This won't be visible in production but even in development it may be irritating. It is useful to have the warnings because these devices return no state, and that can be surprising, leading to github support issues. The warnings is intended to educate you as a developer. If the warnings are troublesome you may try this in your code to suppress them:
    
```javascript
import { YellowBox } from 'react-native';
YellowBox.ignoreWarnings(['Battery state']);
```
</details>

## Release Notes

See the [CHANGELOG.md](https://github.com/react-native-community/react-native-device-info/blob/master/CHANGELOG.md).

## Contributing

Please see the [`contributing guide`](/CONTRIBUTING.md).

## react-native-dom

As a courtesy to developers, this library was made compatible in v0.21.6 with [react-native-dom](https://github.com/vincentriemer/react-native-dom) and [react-native-web](https://github.com/necolas/react-native-web) by providing an empty polyfill in order to avoid breaking builds.

Only [getUserAgent()](#getuseragent) will return a correct value. All other API methods will return an "empty" value of its documented return type: `0` for numbers, `''` for strings, `false` for booleans.
