React Native – Get Device Information

Building a great React Native app more likely requires retrieving the mobile device details like the operating system, version, bundle ID and much more. You probably would need these information to compare versions, or perhaps check if the current operating system is Android or iOS and so on.

Installation of Dependency

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

Run the following command to install

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

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.

Calling the React Native Device Info Plugin

To start reading the device info, you can call any of the following plugin APIs based on what you need to do in your app.

  1. DeviceInfo.getUniqueID() – to get the device unique ID. This ID will change if the app is uninstalled.
  2. DeviceInfo.getManufacturer() – to get the device manufacturer, for example: Apple.
  3. DeviceInfo.getModel() – to get the device model, for example iPhone X.
  4. DeviceInfo.getSystemVersion() – to get the system version, for example, 12.0 or 9.0.
  5. DeviceInfo.getBundleId() – to get the bundle ID, for example, com.myapp.ReactNativeDeviceInfo
  6. DeviceInfo.getBuildNumber() – to get the build number.
  7. DeviceInfo.getVersion() – to get the app version, for example, 1.0.0.
  8. DeviceInfo.getDeviceName() – to get the device name, for example, John’s iPhone.
  9. DeviceInfo.getUserAgent() – to get the user agent, check the app screenshot above.
  10. DeviceInfo.getDeviceLocale() – to get the device locale, for example, en, to display some content that matches device language.
  11. DeviceInfo.getDeviceCountry() – to get the country, for example, US.

Additional Permission for Android

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

<uses-permission android:name="android.permission.ACCESS_WIFI_STATE"/>

App.js

import React, { Component } from 'react';
import { Platform, StyleSheet, View, Text, TouchableOpacity, ScrollView} from 'react-native';

});

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).

Every API returns a Promise but also has 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.
