android: play media in app

During my research in the possibilities of playing audio and video from app, I found several ways of playing media.
The simplest one is to use external player. It was described in the post “Android: how to play audio and video from app“.

Here are some examples how to play media in app.

import android.app.Activity;
import android.media.MediaPlayer;
import android.os.Bundle;
import android.os.Handler;
import android.util.Log;

import android.media.MediaPlayer.OnPreparedListener;
import android.view.MotionEvent;
import android.widget.MediaController;
import android.widget.TextView;

import java.io.IOException;

public class AudioPlayer extends Activity implements OnPreparedListener, MediaController.MediaPlayerControl{
  private static final String TAG = "AudioPlayer";

  public static final String AUDIO_FILE_NAME = "audioFileName";

  private MediaPlayer mediaPlayer;
  private MediaController mediaController;
  private String audioFile;

  private Handler handler = new Handler();

  public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.audio_player);

    audioFile = this.getIntent().getStringExtra(AUDIO_FILE_NAME);
    ((TextView)findViewById(R.id.now_playing_text)).setText(audioFile);

    mediaPlayer = new MediaPlayer();
    mediaPlayer.setOnPreparedListener(this);

    mediaController = new MediaController(this);

    try {
      mediaPlayer.setDataSource(audioFile);
      mediaPlayer.prepare();
      mediaPlayer.start();
    } catch (IOException e) {
      Log.e(TAG, "Could not open file " + audioFile + " for playback.", e);
    }

  }

  @Override
  protected void onStop() {
    super.onStop();
    mediaPlayer.stop();
    mediaPlayer.release();
  }

  @Override
  public boolean onTouchEvent(MotionEvent event) {
    //the MediaController will hide after 3 seconds - tap the screen to make it appear again
    mediaController.show();
    return false;
  }

  //--MediaPlayerControl methods----------------------------------------------------
  public void start() {
    mediaPlayer.start();
  }

  public void pause() {
    mediaPlayer.pause();
  }

  public int getDuration() {
    return mediaPlayer.getDuration();
  }

  public int getCurrentPosition() {
    return mediaPlayer.getCurrentPosition();
  }

  public void seekTo(int i) {
    mediaPlayer.seekTo(i);
  }

  public boolean isPlaying() {
    return mediaPlayer.isPlaying();
  }

  public int getBufferPercentage() {
    return 0;
  }

  public boolean canPause() {
    return true;
  }

  public boolean canSeekBackward() {
    return true;
  }

  public boolean canSeekForward() {
    return true;
  }
  //--------------------------------------------------------------------------------

  public void onPrepared(MediaPlayer mediaPlayer) {
    Log.d(TAG, "onPrepared");
    mediaController.setMediaPlayer(this);
    mediaController.setAnchorView(findViewById(R.id.main_audio_view));

    handler.post(new Runnable() {
      public void run() {
        mediaController.setEnabled(true);
        mediaController.show();
      }
    });
  }
}

Then you need to add xml layout file audio_player.xml

Video can be played in the following Activity:

import android.app.Activity;
import android.media.MediaPlayer;
import android.media.MediaPlayer.OnCompletionListener;
import android.media.MediaPlayer.OnPreparedListener;
import android.net.Uri;
import android.os.Bundle;
import android.util.Log;
import android.view.MotionEvent;
import android.widget.MediaController;
import android.widget.VideoView;

public class VideoPlayer extends Activity implements OnPreparedListener{
	protected VideoView mine;
    protected boolean done = false;
    public static final String AUDIO_FILE_NAME = "audioFileName";
    public static final String DEBUG_TAG = "videoPlay";
    private MediaController mediaController;

    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.video_player);  
        mine = (VideoView) findViewById(R.id.VideoView);   // Save the VideoView for touch event processing
        
        mediaController = new MediaController(this);
        try {
            String myURI = this.getIntent().getStringExtra(AUDIO_FILE_NAME);
            Uri video = Uri.parse(myURI); 
            mine.setVideoURI(video);
            mine.setMediaController(mediaController);
            mine.start();
            mine.setOnCompletionListener(new OnCompletionListener() {

                public void onCompletion(MediaPlayer mp) {  
                    //result.putExtra("com.ejf.convincer01.Finished", true);
                	Log.d(DEBUG_TAG, "Video finished" );
                    done = true;
                }
            });
        } catch (Exception ex) {
            Log.d(DEBUG_TAG, "Video failed: '" + ex + "'" );
        }
    }
    @Override
    public boolean onTouchEvent(MotionEvent event) {
      //the MediaController will hide after 3 seconds - tap the screen to make it appear again
      mediaController.show();
      return false;
    }
	@Override
	public void onPrepared(MediaPlayer mediaPlayer) {
	   
	  }
}

Layout video_player.xml
