react-native-device-info
Device Information for React Native.
TOC
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:
npm install --save react-native-device-info
or using yarn:
yarn 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
-keepclassmembers 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
Android
...
ext {
// dependency versions
We have 3 options for deviceId:
//Option 1 (latest):
firebaseIidVersion = "19.0.1" // default: "19.0.1"
//Option 2 (legacy GooglePlay dependency but using AndroidX):
googlePlayServicesIidVersion = "17.0.0" // default: "17.0.0" - AndroidX
//Option 3 (legacy GooglePlay dependency before AndroidX):
googlePlayServicesIidVersion = "16.0.1"
//include as needed:
compileSdkVersion = "28" // default: 28 (28 is required for AndroidX)
targetSdkVersion = "28" // default: 28 (28 is required for AndroidX)
supportLibVersion = '1.0.2' // Use '28.0.0' or don't specify for old libraries, '1.0.2' or similar for AndroidX
mediaCompatVersion = '1.0.1' // Do not specify if using old libraries, specify '1.0.1' or similar for androidx.media:media dependency
supportV4Version = '1.0.0' // Do not specify if using old libraries, specify '1.0.0' or similar for androidx.legacy:legacy-support-v4 dependency
}
...
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
import DeviceInfo from 'react-native-device-info';
import { 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.
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
DeviceInfo.getApiLevel().then((apiLevel) => {
});
Notes
See API Levels
getAndroidId()
Gets the ANDROID_ID. See API documentation for appropriate use.
Examples
DeviceInfo.getAndroidId().then((androidId) => {
});
getApplicationName()
Gets the application name.
Examples
let appName = DeviceInfo.getApplicationName();

The base OS build the product is based on.
Examples
DeviceInfo.getBaseOs().then((baseOs) => {
});
getBatteryLevel()
Gets the battery level of the device as a float comprised between 0 and 1.
Examples
DeviceInfo.getBatteryLevel().then((batteryLevel) => {
});
Notes
To be able to get actual battery level enable battery monitoring mode for application.
Add this code:
[UIDevice currentDevice].batteryMonitoringEnabled = true;
to AppDelegate.m application:didFinishLaunchingWithOptions:
Returns -1 on the iOS Simulator
getBootloader()
The system bootloader version number.
Examples
DeviceInfo.getBootloader().then((bootloader) => {
});

Gets the device brand.
Examples
let brand = DeviceInfo.getBrand();
getBuildNumber()
Gets the application build number.
Examples
let buildNumber = DeviceInfo.getBuildNumber();
getBundleId()
Gets the application bundle identifier.
Examples
let bundleId = DeviceInfo.getBundleId();
isCameraPresent()
Tells if the device has any camera now.
Examples
DeviceInfo.isCameraPresent()
.then((isCameraPresent) => {
})
.catch((cameraAccessException) => {
});
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
DeviceInfo.getCarrier().then((carrier) => {
});
getCodename()
The current development codename, or the string "REL" if this is a release build.
Examples

Examples
DeviceInfo.getDevice().then((device) => {
});
getDeviceId()
Gets the device ID.
Examples
let deviceId = DeviceInfo.getDeviceId();

Examples
DeviceInfo.getDisplay().then((display) => {
});
getDeviceName()
Gets the device name.
Examples
DeviceInfo.getDeviceName().then((deviceName) => {
});
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.
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
DeviceInfo.getDeviceToken().then((deviceToken) => {
});
getFirstInstallTime()
Gets the time at which the app was first installed, in milliseconds.
Examples
DeviceInfo.getFirstInstallTime().then((firstInstallTime) => {
});
getFingerprint()
A string that uniquely identifies this build.
Examples
DeviceInfo.getFingerprint().then((fingerprint) => {
});
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
DeviceInfo.getFontScale().then((fontScale) => {
});
getFreeDiskStorage()
Method that gets available storage size, in bytes, taking into account both root and data file systems calculation.
Examples
DeviceInfo.getFreeDiskStorage().then((freeDiskStorage) => {
});
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
DeviceInfo.getFreeDiskStorageOld().then((freeDiskStorage) => {
});
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
DeviceInfo.getHardware().then(hardware => {
};
getHost()
Hostname
Examples
DeviceInfo.getHost().then((host) => {
});

Deprecated Gets the device current IP address. (of wifi only)
Switch to react-native-netinfo/netinfo or react-native-network-info
Examples
DeviceInfo.getIpAddress().then((ip) => {
});

Gets the application instance ID.
Examples
DeviceInfo.getInstanceId().then((instanceId) => {
});
Notes
See https://developers.google.com/instance-id/

Gets the time at which the app was last updated, in milliseconds.
Examples
DeviceInfo.getLastUpdateTime().then((lastUpdateTime) => {
});
getMacAddress()
Gets the network adapter MAC address.
Examples
DeviceInfo.getMacAddress().then((mac) => {
});

});
getMaxMemory()
Returns the maximum amount of memory that the VM will attempt to use, in bytes.
Examples
DeviceInfo.getMaxMemory().then((maxMemory) => {
});
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
let model = DeviceInfo.getModel();
getPhoneNumber()
Gets the device phone number.
Examples
DeviceInfo.getPhoneNumber().then((phoneNumber) => {
});
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
getPowerState()
Gets the power state of the device including the battery level, whether it is plugged in, and if the system is currently operating in low power mode.
Displays a warning on iOS if battery monitoring not enabled, or if attempted on an emulator (where monitoring is not possible)
Examples
DeviceInfo.getPowerState().then((state) => {
});
getProduct()
The name of the overall product.
Examples
DeviceInfo.getProduct().then((product) => {

Examples
DeviceInfo.getSerialNumber().then((serialNumber) => {
});
Notes
capability smbios
If you want to use this method in windows, you have to add smbios capability in your aplication. Please following this documentation for add the capability in your manifest file.

});
getTotalDiskCapacity()
Method that gets full disk storage size, in bytes, taking into account both root and data file systems calculation.
Examples
DeviceInfo.getTotalDiskCapacity().then((capacity) => {
});
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
DeviceInfo.getTotalDiskCapacityOld().then((capacity) => {
});
getTotalMemory()
Gets the device total memory, in bytes.
Examples
DeviceInfo.getTotalMemory().then((totalMemory) => {
});
getUniqueId()
This identifier is considered sensitive information in some app stores (e.g. Huawei or Google Play) and may lead to your app being removed or rejected, if used without user consent or for unapproved purposes. Refer to store policies for more information (see notes below).
Gets the device unique ID.
On Android it is currently identical to getAndroidId()
in this module.
On iOS it uses the DeviceUID
uid identifier.
On Windows it uses Windows.Security.ExchangeActiveSyncProvisioning.EasClientDeviceInformation.id
.
Examples
DeviceInfo.getUniqueId().then((uniqueId) => {
});
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
DeviceInfo.syncUniqueId().then((uniqueId) => {
});
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
DeviceInfo.getUsedMemory().then((usedMemory) => {
});
getUserAgent()
Gets the device User Agent.
Examples
DeviceInfo.getUserAgent().then((userAgent) => {
});
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
let version = DeviceInfo.getVersion();

Native interoperatibily
If you need to check for device type from the native side, you can use the following:
import com.learnium.resolver.DeviceTypeResolver
...
deviceTypeResolver = new DeviceTypeResolver(context);
...
if(deviceTypeResolver.isTablet){
...
}else{
...
}
Troubleshooting
When installing or using react-native-device-info
, you may encounter the following problems:
[android] - Unable to merge dex / Multiple dex files / Problems with `com.google.android.gms`
react-native-device-info
uses com.google.android.gms:play-services-gcm
to provide getInstanceId().
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:
compile(project(':react-native-device-info')) {
exclude group: 'com.google.android.gms'
}
[ios] - ld: library not found for -lRNDeviceInfo-tvOS
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
.
[ios] - [NetworkInfo] Descriptors query returned error: Error Domain=NSCocoaErrorDomain Code=4099
“The connection to service named com.apple.commcenter.coretelephony.xpc was invalidated.”
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
[ios] - Multiple versions of React when using CocoaPods
"tries to require 'react-native' but there are several files providing this module"
RN<=59 You may need to adjust your Podfile like this if you use Cocoapods and have undefined symbols or duplicate React definitions
target 'yourTargetName' do
pod 'React', :path => '../node_modules/react-native', :subspecs => [
'Core',
'CxxBridge',
'DevSupport',
'RCTText',
'RCTNetwork',
'RCTWebSocket',
'RCTAnimation',
]
pod 'yoga', :path => '../node_modules/react-native/ReactCommon/yoga'
pod 'RNDeviceInfo', path: '../node_modules/react-native-device-info'
end
post_install do |installer|
installer.pods_project.targets.each do |target|
if target.name == "React"
target.remove_from_project
end
end
end
[tests] - Cannot run my test suite when using this library
react-native-device-info
contains native code, and needs to be mocked. Jest Snapshot support may work though.
If you do not have a Jest Setup file configured, you should add the following to your Jest settings and create the jest.setup.js file in project root:
setupFiles: ['<rootDir>/jest.setup.js'];
You should then add the following to your Jest setup file to mock the DeviceInfo Native Module:
import mockRNDeviceInfo from 'react-native-device-info/jest/react-native-device-info-mock';
jest.mock('react-native-device-info', () => mockRNDeviceInfo);
Checkout the example project for more information.
[warnings] - I get too many warnings (battery state, etc)
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:
import { YellowBox } from 'react-native';
YellowBox.ignoreWarnings(['Battery state']);
Release Notes

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.
