Play audio file (.mp3) from asset folder in android.

import java.io.IOException;
import android.content.Context;
import android.content.res.AssetFileDescriptor;
import android.media.MediaPlayer;

public class AudioPlayer {
  
    String fileName;
    Context contex;
    MediaPlayer mp;

    //Constructor
    public AudioPlayer(String name, Context context) {
        fileName = name;
        contex = context;
        playAudio();
    }

    //Play Audio
    public void playAudio() {
        mp = new MediaPlayer();
        try {
            AssetFileDescriptor descriptor = contex.getAssets()
                    .openFd(fileName);
            mp.setDataSource(descriptor.getFileDescriptor(),
                    descriptor.getStartOffset(), descriptor.getLength());
            descriptor.close();
            mp.prepare();
            mp.setLooping(true);
            mp.start();
            mp.setVolume(3, 3);

        } catch (IllegalArgumentException e) {
            e.printStackTrace();
        } catch (IllegalStateException e) {
            e.printStackTrace();
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
    //Stop Audio
    public void stop() {
        mp.stop();
    }
}


Call this class from any activity like as new AudioPlayer(file_name, mContext);

Hello Francois,

Code snippet to input file name in each coding.

String ringtoneFileName = "Ringtone1.mp3";

AudioPlayer audioPlayer = new AudioPlayer(ringtoneFileName,context);

audioPlayer.playAudio();
