I'm trying to implement the restart of MediaPlayer in Android, when errors happen (connection with server lost, network is unreachable and other). I've seen many code examples, but all are somewhat non-standard. I think there must be the standard way to restart corresponding to the developer.android.com, but it's not clear from here, how to set the listener which would restart player on such errors.
Here are the parts of my code:
public class PlayerService extends Service implements OnErrorListener {
....
////////////////////
this.mplayer = MediaPlayer.create(c, Uri.parse(url));
mplayer.setOnErrorListener(onErrorListener);
////////////////////
MediaPlayer.OnErrorListener onErrorListener = new MediaPlayer.OnErrorListener()
{
@Override
public boolean onError(MediaPlayer mp, int what, int extra)
{
Log.e(getPackageName(), String.format("Error(%s%s)", what, extra));
playlist="ERROR";
restart();
return true;
}
};
@Override
public boolean onError(MediaPlayer player, int what, int extra) {
restart();
return true;
};
public void restart()
{
try
{
playlist="RELOADING";
for (int u=1; u<=5; u++)
{
Thread.sleep(5000);
mplayer.stop();
mplayer.release();
mplayer=null;
playSong(getApplicationContext(),currenturl);
};
}
catch (Exception e)
{
playlist="RELOADING ERROR";
}
}
//////////////
....
}
Am I setting the listener right? I'm not sure where to put onError function so I have 2 of them. When I emulate the error by setting the phone to the flight mode, the listener fires "RELOADING" and "RELOADING ERROR" title. But after the network is on, no restart of the player happens. There is no sound.
What's wrong here? The player cannot restart.
Please help to make the code workable. Also can be connection skips and IO Exception.
Overview
I ran into a similar issue and based on the documentation it indicates that all you need to do is reset your media player:
What you are currently doing is stopping and releasing (
mplayer.stop()
andmplayer.release()
) a media player that is in the Error state. This should be causing something like an IllegalStateException to be raised. If it's not throwing an error you would still be trying to start a song in a null object. Instead of calling stop and release then setting the variable to null you should be using themplayer.reset()
function.Another option would be to initiate a new media player but the documentation details the subtle difference between a newly instantiated MediaPlayer object and one that has had
reset()
called on it.Reset after Error
Based on this information something like the following should fix your issue:
See media player constant documentation for a list of potential errors.
Setting Error Listener
As for setting the error listener, here is how I've implemented it in the past:
I then handle loading up the media player in another function initiated by onResume().
