Setup

Expecting you have the React Native development environment in place, are starting with a React Native hello world project and have managed to run it on an actual Android/iOS device:

  1. Install library via npm:

    npm install --save @react-native-community/audio-toolkit
    
  2. Link the library by either:

    1. Linking automatically using:
      react-native link @react-native-community/audio-toolkit
      
    2. Linking manually by following steps 1-3 of the Android/iOS setup below.
  3. Regardless of whether you link automatically or manually in step 2, make sure to check out step 4 of the Android/iOS setup below as some manual changes may be required.

Android setup

  1. Append dependency to end of android/settings.gradle file

    ...
    
    include ':@react-native-community_audio-toolkit'
    project(':@react-native-community_audio-toolkit').projectDir = new File(rootProject.projectDir, '../node_modules/@react-native-community/audio-toolkit/android')
    
  2. Add dependency to android/app/build.gradle

    ...
    
    dependencies {
        ...
        implementation project(':@react-native-community_audio-toolkit')
    }
    
  3. Register the module in android/app/src/main/java/com/<project>/MainApplication.java

    package com.<project>;
    
    import com.facebook.react.ReactActivity;
    import com.facebook.react.ReactPackage;
    import com.facebook.react.shell.MainReactPackage;
    
    import com.reactnativecommunity.rctaudiotoolkit.AudioPackage; // <-------- here
    
    ...
    
    protected List<ReactPackage> getPackages() {
        return Arrays.<ReactPackage>asList(
            ...
            new MainReactPackage(),
            new AudioPackage() // <------------------------------- here
        );
    }
  4. (optional) Doing specific tasks with this library requires adding permissions to your Android manifest file, which can be found at android/app/src/main/AndroidManifest.xml

    <manifest ...>
    
        <!-- If you want to play audio from a SD card (i.e. external storage),
             you need to add this permission -->
        <uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
    
        <!-- If you want to play audio from a URL, you need to add these permissions -->
        <uses-permission android:name="android.permission.INTERNET" />
        <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
    
        <!-- If you want to record audio, you need to add this permission -->
        <uses-permission android:name="android.permission.RECORD_AUDIO" />
    
        <!-- If you want to record audio to a SD card (i.e. external storage),
             you need to add this permission -->
        <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
        ...
    
    </manifest>

    For versions of Android earlier than Android 6.0, the user is asked to agree to permission when installing the app. However, on Android 6.0+ the app developer is responsible for asking for permissions before they are required.

    For an example of this in action, check out the code in the ExampleApp at ExampleApp/src/App.js or check out the documentation for PermissionsAndroid.

iOS setup

React Native 0.59 and earlier:

  1. Right click Libraries, click Add Files to "ExampleApp"

  2. Select node_modules/@react-native-community/audio-toolkit/ios/ReactNativeAudioToolkit/ReactNativeAudioToolkit.xcodeproj

  3. Select your app from the Project Navigator, click on the Build Phases tab. Expand Link Binary With Libraries. Click the plus and add libReactNativeAudioToolkit.a from under Workspace.

  4. Add a usage description to Info.plist.

       <string>This app requires access to your microphone</string>
    

React Native 0.60 and later

  • Follow step 4 above. Steps 1 - 3 are not required.

Play some media!

  • Include the JavaScript library:

    import {
        Player,
        Recorder,
        MediaStates
    } from '@react-native-community/audio-toolkit';
    
    ...
  • Create a button for triggering our example:

    import {
      ...
      TouchableHighlight
    } from 'react-native';
    
    class MyApp extends React.Component {
      constructor() {
        super();
        this.state = {
          disabled: false
        };
      }
    
      _onPress() {
        ...
      }
    
      render() {
        return (
          ...
          <TouchableHighlight disabled={this.state.disabled} onPress={() => this._onPress()}>
            <Text>
              Press me!
            </Text>
          </TouchableHighlight>
          ...
  • Fill in _onPress() handler with example code:

    _onPress() {
      // Disable button while recording and playing back
      this.setState({disabled: true});
    
      // Start recording
      let rec = new Recorder("filename.mp4").record();
    
      // Stop recording after approximately 3 seconds
      setTimeout(() => {
        rec.stop((err) => {
          // NOTE: In a real situation, handle possible errors here
    
          // Play the file after recording has stopped
          new Player("filename.mp4")
          .play()
          .on('ended', () => {
            // Enable button again after playback finishes
            this.setState({disabled: false});
          });
        });
      }, 3000);
    }
  • Run app with react-native run-android or react-native run-ios

Where to go next?

You can’t perform that action at this time.
