v6 to v7 upgrade

Your iOS Podfile will need to move to an iOS 10 minimum. v7 of this module no longer supports iOS9.

Installation

Using npm:

1npm install --save react-native-device-info

or using yarn:

1yarn add react-native-device-info

Proguard

If you want to use Install Referrer tracking, you will need to add this config to your Proguard config

-keep class com.android.installreferrer.api.** {
  *;
}

If you are experiencing issues with hasGms() on your release apks, please add the following rule to your Proguard config

-keep class com.google.android.gms.common.** {*;}

AndroidX Support

This module defaults to AndroidX you should configure your library versions similar to this in your android/build.gradle file's "ext" block

1...
2  ext {
3    // dependency versions
4
5    We have 3 options for deviceId:
6    //Option 1 (latest):
7    firebaseIidVersion = "19.0.1" // default: "19.0.1"
8    //Option 2 (legacy GooglePlay dependency but using AndroidX):
9    googlePlayServicesIidVersion = "17.0.0" // default: "17.0.0" - AndroidX
10    //Option 3 (legacy GooglePlay dependency before AndroidX):
11    googlePlayServicesIidVersion = "16.0.1"
12
13
14    //include as needed:
15    compileSdkVersion = "28" // default: 28 (28 is required for AndroidX)
16    targetSdkVersion = "28" // default: 28 (28 is required for AndroidX)
17    supportLibVersion = '1.0.2' // Use '28.0.0' or don't specify for old libraries, '1.0.2' or similar for AndroidX
18    mediaCompatVersion = '1.0.1' // Do not specify if using old libraries, specify '1.0.1' or similar for androidx.media:media dependency
19    supportV4Version = '1.0.0' // Do not specify if using old libraries, specify '1.0.0' or similar for androidx.legacy:legacy-support-v4 dependency
20  }
21...

If you need non-AndroidX you will need to use the jetifier package in reverse mode, documentation available with that package.

Linking

Linking in native modules is a frequent source of trouble for new react-native developers, resulting in errors like "RNDeviceInfo is null" etc. For this reason automatic linking was implemented, and it should be used in your project.

Automatic linking is supported for all platforms (even windows on React native >= 0.63!)

Previous versions need to do manual linking. No support is offered for these previous react-native versions but you may refer to older versions of this README if you like. Upgrade to modern versions of react-native. Use upgrade-helper tool on the internet if needed.

Usage

1import DeviceInfo from 'react-native-device-info';
2
3// or ES6+ destructured imports
4
5import { getUniqueId, getManufacturer } from 'react-native-device-info';

API

Note that many APIs are platform-specific. If there is no implementation for a platform, then the "default" return values you will receive are "unknown" for string, -1 for number, and false for boolean. Arrays and Objects will be empty ([] and {} respectively).

Most APIs return a Promise but also have a corresponding API with Sync on the end that operates synchronously. For example, you may prefer to call isCameraPresentSync() during your app bootstrap to avoid async calls during the first parts of app startup.

Note about getUserAgentSync

While the asynchronous method getUserAgent is available on both platforms, getUserAgentSync is only supported on Android.

The example app in this repository shows an example usage of every single API, consult the example app if you have questions, and if you think you see a problem make sure you can reproduce it using the example app before reporting it, thank you.

getApiLevel()

Gets the API level.

Examples

1DeviceInfo.getApiLevel().then((apiLevel) => {
2  // iOS: ?
3  // Android: 25
4  // Windows: ?
5});

Examples

1DeviceInfo.getBaseOs().then((baseOs) => {
2  // "Windows", "Android" etc
3});

getBatteryLevel()

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

Examples

1DeviceInfo.getBatteryLevel().then((batteryLevel) => {
2  // 0.759999
3});

Notes

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

1[UIDevice currentDevice].batteryMonitoringEnabled = true;

to AppDelegate.m application:didFinishLaunchingWithOptions:

Returns -1 on the iOS Simulator

getBootloader()

Examples

1DeviceInfo.getBootloader().then((bootloader) => {
2  // "mw8998-002.0069.00"
3});

getBrand()

Gets the device brand.

Examples

1let brand = DeviceInfo.getBrand();
2// iOS: "Apple"
3// Android: "xiaomi"
4// Windows: ?

getBuildNumber()

Gets the application build number.

Examples

1let buildNumber = DeviceInfo.getBuildNumber();
2// iOS: "89"
3// Android: "4"
4// Windows: ?

getBundleId()

Gets the application bundle identifier.

2  .then((isCameraPresent) => {
3    // true or false
4  })
5  .catch((cameraAccessException) => {
6    // is thrown if a camera device could not be queried or opened by the CameraManager on Android
7  });

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, isCameraPresent will still return the true

getCarrier()

Gets the carrier name (network operator).

Examples

1DeviceInfo.getCarrier().then((carrier) => {
2  // "SOFTBANK"
3});

getCodename()

The current development codename, or the string "REL" if this is a release build.

Examples

1DeviceInfo.getCodename().then((codename) => {

2  // iOS: "Becca's iPhone 6"
3  // Android: ?
4  // Windows: ?
5});

This used to require the android.permission.BLUETOOTH but the new implementation in v3 does not need it. You may remove that from your AndroidManifest.xml if you had it for this API. iOS 16 and greater require entitlements to access user-defined device name, otherwise a generic value is returned (ie. 'iPad', 'iPhone')

getDeviceToken()

Gets the device token (see DeviceCheck). Only available for iOS 11.0+ on real devices. This will reject the promise when getDeviceToken is not supported, be careful with exception handling.

Examples

1DeviceInfo.getDeviceToken().then((deviceToken) => {
2  // iOS: "a2Jqsd0kanz..."
3});

getFirstInstallTime()

3});

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 )

Examples

1DeviceInfo.getFontScale().then((fontScale) => {
2  // 1.2
3});

getFreeDiskStorage()

Method that gets available storage size, in bytes, taking into account both root and data file systems calculation.

Examples

1DeviceInfo.getFreeDiskStorage().then((freeDiskStorage) => {
2  // Android: 17179869184
3  // iOS: 17179869184
4});

Notes

The API used by this method for Android was changed in v6.0.0. The older version has been maintained below as getFreeDiskStorageOld(). On iOS, getFreeDiskStorage() and getFreeDiskStorageOld() return the same value.

getFreeDiskStorageOld()

Old implementation of method that gets available storage size, in bytes.

Examples

1DeviceInfo.getFreeDiskStorageOld().then((freeDiskStorage) => {
2  // Android: 17179869184
3  // iOS: 17179869184
4});

Notes

From developer.android.com:

This method was deprecated in API level 29.

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.

getHardware()

The name of the hardware (from the kernel command line or /proc).

Examples

1DeviceInfo.getHardware().then(hardware => {
2  // "walleye"
3};

getHost()

Hostname

Examples

1DeviceInfo.getHost().then((host) => {
2  // "wprd10.hot.corp.google.com"
3});

getIpAddress()

Deprecated Gets the device current IP address. (of wifi only) Switch to react-native-netinfo/netinfo or react-native-network-info

Examples

1DeviceInfo.getIpAddress().then((ip) => {
2  // "92.168.32.44"
3});

Android Permissions

Notes

Support for iOS was added in 0.22.0

getIncremental()

The internal value used by the underlying source control to represent this build.

Examples

1DeviceInfo.getIncremental().then((incremental) => {
2  // "4820017"
3});

getInstallerPackageName()

The internal value used by the underlying source control to represent this build.

Examples

1DeviceInfo.getInstallerPackageName().then((installerPackageName) => {
2  // Play Store: "com.android.vending"
3  // Amazon: "com.amazon.venezia"
4  // Samsung App Store: "com.sec.android.app.samsungapps"
5  // iOS: "AppStore", "TestFlight", "Other"
6});

getInstallReferrer()

Gets the referrer string upon application installation.

Examples

1DeviceInfo.getInstallReferrer().then((installReferrer) => {
2  // If the app was installed from https://play.google.com/store/apps/details?id=com.myapp&referrer=my_install_referrer
3  // the result will be "my_install_referrer"
4});

getInstanceId()

Gets the application instance ID.

This attempts to get an instance ID from these sources, in this order:

• a value under key instanceId in SharedPreferences file react-native-device-info
• Firebase IID (if firebaseBomVersion or firebaseIidVersion is defined in gradle ext - deprecated)
• GMS IID (if googlePlayServicesIidVersion or googlePlayServicesVersion is defined in gradle ext - deprecated)
• a random UUID generated from java.util.UUID.randomUUID() and stored in SharedPreferences

If you are using the deprecated sources, the instance ID generated is stored in shared preferences so it will be stable during this major version of react-native-device-info.

In a future version of react-native-device-info, the Firebase IID and GMS IID implementations will be removed, and all future values will be the value (if any) stored in SharedPreferences, or a new random UUID that will then be stored and used for that app installation in the future.

Examples

1DeviceInfo.getInstanceId().then((instanceId) => {
2  // Android: da4e0245-5d6c-402a-a07c-0c5349f229e2
3});

Notes

See https://developers.google.com/instance-id/

getLastUpdateTime()

Gets the time at which the app was last updated, in milliseconds.

Examples

2  // 402653183
3});

getModel()

Gets the device model.

iOS warning: The list with device names is maintained by the community and could lag new devices. It is recommended to use getDeviceId() since it's more reliable and always up-to-date with new iOS devices. We do accept pull requests that add new iOS devices to the list with device names.

Examples

1let model = DeviceInfo.getModel();
2// iOS: ?
3// Android: ?
4// Windows: ?

getPhoneNumber()

Gets the device phone number.

Examples

1DeviceInfo.getPhoneNumber().then((phoneNumber) => {

3});

Android Permissions

Please refer to the Android docs for information about which permission you need, depending on which version of Android you are supporting. Read the note below for more information.

Notes

This can return undefined in certain cases and should not be relied on. SO entry on the subject.

If the above permissions do not work, you can try using android.permission.READ_SMS. However, this is not in the Android docs. If you are supporting Android 10 and below: android.permission.READ_PHONE_STATE. If you are supporting Android 11 and up: android.permission.READ_SMS

4});

Notes

The API used by this method for Android was changed in v6.0.0. The older version has been maintained below as getTotalDiskCapacityOld(). On iOS, getTotalDiskCapacity() and getTotalDiskCapacityOld() return the same value.

getTotalDiskCapacityOld()

Old implementation of method that gets full disk storage size, in bytes.

Examples

1DeviceInfo.getTotalDiskCapacityOld().then((capacity) => {
2  // Android: 17179869184

4// Windows: "{2cf7cb3c-da7a-d508-0d7f-696bb51185b4}"
5});

Notes

• iOS: This is IDFV or a random string if IDFV is unavaliable. Once UID is generated it is stored in iOS Keychain and NSUserDefaults. So it would stay the same even if you delete the app or reset IDFV. You can carefully consider it a persistent, cross-install unique ID. It can be changed only in case someone manually override values in Keychain/NSUserDefaults or if Apple would change Keychain and NSUserDefaults implementations. Beware: The IDFV is calculated using your bundle identifier and thus will be different in app extensions.
• android: Prior to Oreo, this id (ANDROID_ID) will always be the same once you set up your phone.
• android: Google Play policy, see "persistent device identifiers". Huawei - AppGallery Review Guidelines see "permanent device identifier" and "obtaining user consent".

syncUniqueId()

This method is intended for iOS.

This synchronizes uniqueId with IDFV or sets new a random string.

On iOS it uses the DeviceUID uid identifier. On other platforms it just call getUniqueId() in this module.

Examples

1DeviceInfo.syncUniqueId().then((uniqueId) => {
2  // iOS: "FCDBD8EF-62FC-4ECB-B2F5-92C9E79AC7F9"
3  // Android: "dd96dec43fb81c97"
4  // Windows: ?
5});

Notes

• If user moved or restored data from one iOS device to second iOS device then he will have two different devices with same uniqueId in Keychain/NSUserDefaults. User can call syncUniqueId() on new iOS device. That will update his uniqueId from IDFV or a random string.

getUsedMemory()

Gets the app memory usage, in bytes.

⚠️ A note from the Android docs.

Note: this method is only intended for debugging or building a user-facing process management UI.

Examples

1DeviceInfo.getUsedMemory().then((usedMemory) => {
2  // 23452345
3});

getSupportedMediaTypeList()

This method gets the list of supported media codecs.

Examples

3  // tvOS: not available
4  // Android: "Mozilla/5.0 (Linux; Android 12; sdk_gphone64_arm64 Build/SE1A.220630.001; wv) AppleWebKit/537.36 (KHTML, like Gecko) Version/4.0 Chrome/91.0.4472.114 Mobile Safari/537.36"
5  // Windows: ?
6});

getVersion()

Gets the application version. Take into account that a version string is device/OS formatted and can contain any additional data (such as build number etc.). If you want to be sure about version format, you can use a regular expression to get the desired portion of the returned version string.

Examples

1let version = DeviceInfo.getVersion();
2// iOS: "1.0"
3// Android: "1.0" or "1.0.2-alpha.12"
4// Windows: ?

isAirplaneMode()

=======

Native interoperatibily

If you need to check for device type from the native side, you can use the following:

1import com.learnium.resolver.DeviceTypeResolver
2
3...
4deviceTypeResolver = new DeviceTypeResolver(context);
5...
6//Check if the device is a Tablet:
7if(deviceTypeResolver.isTablet){
8  ...
9}else{
10  ...
11}

Troubleshooting

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

1 compile(project(':react-native-device-info')) {
2    exclude group: 'com.google.android.gms'
3}

1target 'yourTargetName' do
2  # See http://facebook.github.io/react-native/docs/integration-with-existing-apps.html#configuring-cocoapods-dependencies
3  pod 'React', :path => '../node_modules/react-native', :subspecs => [
4    'Core',
5    'CxxBridge', # Include this for RN >= 0.47
6    'DevSupport', # Include this to enable In-App Devmenu if RN >= 0.43
7    'RCTText',
8    'RCTNetwork',
9    'RCTWebSocket', # Needed for debugging
10    'RCTAnimation', # Needed for FlatList and animations running on native UI thread
11    # Add any other subspecs you want to use in your project
12  ]
13
14  # Explicitly include Yoga if you are using RN >= 0.42.0
15  pod 'yoga', :path => '../node_modules/react-native/ReactCommon/yoga'
16
17  # Third party deps podspec link - you may have multiple pods here, just an example
18  pod 'RNDeviceInfo', path: '../node_modules/react-native-device-info'
19
20end
21
22# if you see errors about React duplicate definitions, this fixes it. The same works for yoga.
23post_install do |installer|
24  installer.pods_project.targets.each do |target|
25    if target.name == "React"
26      target.remove_from_project
27    end
28  end
29end

react-native-dom

As a courtesy to developers, this library was made compatible in v0.21.6 with react-native-dom and react-native-web by providing an empty polyfill in order to avoid breaking builds.

Only 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.
