React Native Get Unique ID of Device

Every mobile device in the world has its unique ID which is a combination of Alphabetic and Numeric characters. To get the device’s Unique ID and we can use the react-native-device-info library.

The unique device ID is used to identify a device uniquely. For example, if you are making an application which requires a unique device dependent login mechanism like WhatsApp where you want the user to log in from a single device at a time then you can use device unique ID to track the single device login.

So let’s get started with the example to Get Unique ID of Device.

To Make a React Native App

Getting started with React Native will help you to know more about the way you can make a React Native project. We are going to use react-native init to make our React Native App. Assuming that you have node installed, you can use npm to install the react-native-cli command line utility. Open the terminal and go to the workspace and run

npm install -g react-native-cli

Run the following commands to create a new React Native project

react-native init ProjectName

If you want to start a new project with a specific React Native version, you can use the --version argument:

react-native init ProjectName --version X.XX.X
react-native init ProjectName --version react-native@next

This will make a project structure with an index file named App.js in your project directory.

Installation of Dependency

To use DeviceInfo we need to install react-native-device-info package. To install this

Open the terminal and jump into your project

Run the following command

This command will copy all the dependencies into your node_module directory. –save is optional, it is just to update the react-native-device-info dependancy in your package.json file.

CocoaPods Installation

After the updation of React Native 0.60, they have introduced autolinking so we do not require to link the library but need to install pods. So to install pods use

Now Open App.js in any code editor and replace the code with the following code.

App.js

To Run the React Native App

Open the terminal again and jump into your project using.
cd ProjectName
To run the project on an Android Virtual Device or on real debugging device
react-native run-android
or on the iOS Simulator by running
react-native run-ios (macOS only).

      

This is how you can get the Unique ID of Device. If you have any doubt or you want to share something about the topic you can comment below or contact us here. There will be more posts coming soon. Stay tuned!

  1. Firstly thanks for this fabulous website, it helps me a lot.
    I have created one new react native project with version 0.61.4, and then run this example, it is working fine.
    I have run the same example on new react native project with version number ^0.59.10, But it is not working, I have configured all linking changes (for React Native <= 0.59) needed to run react-native-device-info library as suggested in react-native-device-info official github page.

    I didn't understand this line, in official doc…..
    "If you need non-AndroidX you will need to use the jetifier package in reverse mode, documentation available with that package."
    i try to fix this by adding following lines in gradle.properties file
    android.useAndroidX=false
    android.enableJetifier=false

    but it is not working.

    • Hi,
      I was able to resolve this issue and get it working.
      I wanted the non-AndroidX version of this npm module. I used the jetifier package in reverse mode.
      Following were the steps I followed
      1.npm install –save-dev jetifier
      2. npx jetify -r
      and then
      npx react-native run-android
      your code will compile properly

      If you are facing merge dex / Multiple dex files / Problems with com.google.android.gms
      Use this in your build.gradle
      compile(project(‘:react-native-device-info’)) {
      exclude group: ‘com.google.android.gms’
      }
      instead of implementation project(‘:react-native-device-info’)

      @Snehal Agrawal correct me if I am wrong
