Question

I have following code to play small audio files

private void playVoice() {

     if (mPlayVoice != null) {
         if (mPlayVoice.isPlaying()) {
             mPlayVoice.release();
             mPlayVoice = null;
         }
     }
     mPlayVoice = 
         MediaPlayer.create(BirdsActivity.this, mSoundIds[getCurrentIndex()]);
     mPlayVoice.start();
 }

It works fine in Samsung galaxy tab but gives below error in small device(I Checked in Sony xperia mini pro my project)

Answer 1

You’re doing this:

 PlayVoice.release(); 

Do you not mean

 mPlayVoice.release(); 

If you have other issues this is the best document to consult:

Android MediaPlayer

EDIT

Ok if you are here: isPlaying() Invalid States it show’s you’re trying to call isPlaying() while the player is in the error state. So you need to work out why it is already in the error state.

In general, some playback control operation may fail due to various reasons, such as unsupported audio/video format, poorly interleaved audio/video, resolution too high, streaming timeout, and the like.

Have a look at adding an error listener: setOnErrorListener()
