Media Player start stop start

Question

I am making a new android sound application. I made a clickable button to play sound when I click on it. But I also want it to stop playing sound when I click for the second

Answer 1

You're calling mpButtonClick1.reset() after mpButtonClick1.stop() - don't do that:

if (mpButtonClick1.isPlaying()) {
    mpButtonClick1.stop();
    mpButtonClick1.reset(); //<--------- calling reset(), remove this line
}

The docs for reset() say:

Resets the MediaPlayer to its uninitialized state. After calling this method, you will have to initialize it again by setting the data source and calling prepare().

Remove mpButtonClick1.reset() and it should work.

Keep in mind that MediaPlayer works as a state machine, which means that if you call methods in the wrong order, you'll get problems. Please read about MediaPlayer here and here.

In my experience when I need to play multiple times and I may need to stop one play to start another play, (like in the case of multiple buttons), I just create another player, making sure that I release the resources for the previous one. To stop just use

mediaPlayer.stop(); 

But for play use something like this (adapt the logging to your specific needs) to create/recreate your player:

private boolean createMediaPlayer()
{
    if (mediaPlayer!=null)
    {
        if(mediaPlayer.isPlaying())
        {
            mediaPlayer.stop();
            mediaPlayer.reset();
            mediaPlayer.release();
            mediaPlayer=null;
        }

    }
    mediaPlayer = new MediaPlayer();
    mediaPlayer.setVolume(1f, 1f);
    try
    {
        mediaPlayer.setAudioStreamType(Interop.PRIMARY_STREAM);
        mediaPlayer.setDataSource(m_soundFile);
        mediaPlayer.prepare();
        return true;
        // Interop.logDebug(TAG + "-loadAudio: SUCCESS" + m_soundFile);
    } catch (Exception e)
    {
        Interop.logError(TAG + "-LoadAudio for Clic Sound: audioPlayer prepare failed for current file: " + m_soundFile);
        Interop.logError(TAG + "-Exception: " , e);
        return false;
    }
}

and than use

if (createMediaPlayer())
    mediaPlayer.start();

this will ensure proper release of the resources used by the media player.

Try this: You should use only one mediaplayer object

    public class PlayaudioActivity extends Activity {

    private MediaPlayer mp;

    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);
    Button b = (Button) findViewById(R.id.button1);
    Button b2 = (Button) findViewById(R.id.button2);
    final TextView t = (TextView) findViewById(R.id.textView1);

    b.setOnClickListener(new View.OnClickListener() {

        @Override
        public void onClick(View v) {
        stopPlaying();
        mp = MediaPlayer.create(PlayaudioActivity.this, R.raw.far);
        mp.start();
        }

    });

    b2.setOnClickListener(new View.OnClickListener() {

        @Override
        public void onClick(View v) {
        stopPlaying();
        mp = MediaPlayer.create(PlayaudioActivity.this, R.raw.beet);
        mp.start();
        }
    });
    }

    private void stopPlaying() {
        if (mp != null) {
            mp.stop();
            mp.release();
            mp = null;
       }
    }
}
