IllegalStateException for MediaPlayer.prepareAsync

Question

05-19 11:52:51.622: ERROR/MediaPlayer(1291): prepareAsync called in state 8 05-19 11:52:51.622: WARN/System.err(1291): java.lang.IllegalStateException 

try {     mp = MediaPlayer.create(             Main.this,             Uri.parse("http://codejanitor.us/good.mp3"));     mp.setOnPreparedListener(new OnPreparedListener() {         @Override         public void onPrepared(MediaPlayer mp) {             mp.start();         }     });     try {         mp.prepareAsync();     } catch (IllegalStateException e) {         e.printStackTrace();     } } finally {     if (mp != null) {         mp.release();         mp = null;     } } 

ALTERNATELY

If I do:

try {     mp = MediaPlayer.create(             AmazonClipActivity.this,             Uri.parse("http://codejanitor.us/good.mp3"));     mp.setOnPreparedListener(new OnPreparedListener() {         @Override         public void onPrepared(MediaPlayer mp) {             mp.start();         }     }); } finally {     if (mp != null) {         mp.release();         mp = null;     } } 

I get:

05-19 12:22:57.472: DEBUG/MediaPlayer(1635): Couldn't open file on client side, trying server side 05-19 12:22:57.472: INFO/StagefrightPlayer(68): setDataSource('http://codejanitor.us/good.mp3') 05-19 12:22:57.482: INFO/NuHTTPDataSource(68): connect to codejanitor.us:80/good.mp3 @0 05-19 12:23:00.632: INFO/NuCachedSource2(68): ERROR_END_OF_STREAM 

Answer 1

mp = MediaPlayer.create(...); is already preparing the MediaPlayer returned, so you cannot call prepare (or its variants) again (and there is no need for onPreparedListener as well).
