Example to Get Device Information in React Native

Example to Get Device Information in React Native

This is an Example to Get Device Information in React Native. To get the device information in React Native will use the react-native-device-info library.

In this example, we will show you how to get all the information about the device using a single library. We will get the following details in this example.

So let’s get started with the example to Get Device Info.

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 dependency.

To install this open the terminal and jump into your project using

Run the following command to install

This command will copy all the dependencies into your node_module directory, You can find the directory in node_module directory named react-native-device-info.

–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

Additional Permission for Android

To use getIPAddress in Android you need to get the permission in Android. So to get the permission, add the blow line into your AndroidManifest.xml

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).

IOS

   

Android

      

This is how you can get the Device Info. 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!

Hope you liked it. 🙂

  1. First of all, thanks a lot for the tutorial, such tutorials really help for beginners.

    Secondly, when I tried to implement the code, it doesn’t show the information for me. It just shows [object Object] in place of the info. Any clue how to solve this?
