react-native-installed-app-checker is a React Native module that allows you to check if a specific application is installed on the device. This module supports Android platform.

Installation

npm install [email protected]

Android Specific Setup

Permissions In order to check if an app is installed, you'll need to request the QUERY_ALL_PACKAGES permission. Add the following permission to your AndroidManifest.xml:

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

This permission allows the app to query the list of all installed apps on the device. Note that using this permission requires justification, and you should check the Google Play policies if you plan to distribute your app through the Play Store.

Android 11 and Above Starting with Android 11 (API level 30), Google has introduced additional restrictions for accessing installed apps. To handle this properly, you may need to provide a rationale for why your app requires the QUERY_ALL_PACKAGES permission. For more information, see the Google Play policies.

Usage

import React from 'react';
import { View, Button, Alert } from 'react-native';
import RNInstalledAppChecker from 'react-native-installed-app-checker';

const App = () => {
  const checkAppInstalled = (packageName) => {
    RNInstalledAppChecker.isAppInstalled(packageName, (isInstalled) => {
      if (isInstalled) {
        Alert.alert('App Installed', `${packageName} is installed.`);
      } else {
        Alert.alert('App Not Found', `${packageName} is not installed.`);
      }
    });
  };

  return (
    <View style={{ padding: 20 }}>
      <Button title="Check App Installation" onPress={() => checkAppInstalled('com.example.otherapp')} />
    </View>
  );
};

export default App;
