you cannot use library that use native code with expo see caveats if you want to use native code you need to create your project with native code at getting started doc basically

  1. install pre request apps (node - Java Development Kit - android studio - xcode - react native cli )
  2. run command react-native init MyProjectName
  3. cd your project folder cd MyProjectName
  4. run react-native run-android or react-native run-ios

if you want to convert expo project to native code project you can do ejecting-from-create-react-native-app

  1. install native code requirement as above
  2. run npm run eject

after that you can use third party libraries that use native code and run react-native link

react-native-device-info, Unique Id of Device. Every mobile device in the world has its unique ID which is a combination of Alphabetic and Numeric characters.

Instead of expo you can create a project using react-native CLI.

Create a new project using command :

cd Myproject

Run the project using the following command :

react-native run-android

I tried with following versions and it worked for me.

  "react": "16.0.0",
  "react-native": "0.50.4",
  "react-native-device-info": "^0.12.1",

I installed it with command :

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

Then I link it with command :

react-native link react-native-device-info

If you are facing any issue while linking the package then you can do the manual link or you can cross check the packages is successfully link or not.

  1. in android/app/build.gradle:
 dependencies {
        compile "com.facebook.react:react-native:+"  // From node_modules
    +   compile project(':react-native-device-info')
  1. in android/settings.gradle:


include ':app'

include ':react-native-device-info'

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

  1. in
+ import com.learnium.RNDeviceInfo.RNDeviceInfo;

  public class MainApplication extends Application implements ReactApplication {

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



Add the appropriate, optional permissions to your AndroidManifest.xml:

<uses-permission android:name="android.permission.BLUETOOTH"/>         <!-- for Device Name -->
<uses-permission android:name="android.permission.READ_PHONE_STATE"/>  <!-- for Phone Number -->


var DeviceInfo = require('react-native-device-info');
// or import DeviceInfo from 'react-native-device-info';

var deviceId = DeviceInfo.getUniqueID();
