private MediaPlayer mp;
 
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    mp=new MediaPlayer();
    audioPlayer(context,uri);
}
 
public void audioPlayer(Context context,Uri uri){
    mp= MediaPlayer.create(context, uri);
    mp.start();
}

From the official docs:
"public static MediaPlayer create (Context context, Uri uri)
Convenience method to create a MediaPlayer for a given Uri. On success, prepare() will already have been called and must not be called again.
When done with the MediaPlayer, you should call release(), to free the resources. If not released, too many MediaPlayer instances will result in an exception."

I have yet to get an exception from mediaplayer, but to make sure it won't happen, don't forget to realese(), at least in onDestroy()!

@Override
protected void onPause() {
    super.onPause();
    if(mp.isPlaying()){ //you need to check if it is playing first, or you might get a null pointer exception!
        mp.stop();
    }
}

Depending on your needs, you can put the mp.stop() in the onPause part, so if the activity goes to the background for whatever reason, it will only pause the playback, and it can continue it in onResume(). Just put mp.play() in onResume().

@Override
 public void onDestroy(){
 super.onDestroy();
    mp.release();
 }

As an alternative, you could set up an onCompletionListener, so when the media playback is done, it will release the media player.

mp.setOnCompletionListener(new OnCompletionListener(){
    @Override
    public void onCompletion(MediaPlayer mp) {
        mp.release();
    }
 });
