问题
I want to play device ringtones with MediaPlayer yet it seems when the metadata tag
ANDROID_LOOP = true
is set MediaPlayer is ignoring the call of the method setLooping
mMediaPlayer.setLooping(false);
and loops the audio in any case. Also the onCompletionListener method is not called.
I noticed that even audio apps like ES Media Player loop audios with this tag set to true regardless if looping is enabled or not.
So my question is if I can
- make MediaPlayer ignoring this tag
- temporary modify the tag so that MediaPlayer does not loop the audio
This question arose around ringtones yet it is of course not ringtone specific. Funnily the tutorials I found on how to play ringtones all set mMediaPlayer.setLooping(true); so that they dont have to handle this problem it seems ...
Thanks

Might not be a satisfactory answer, but it seems the engineers are not inclined to change the behavior of MediaPlayer and the metadata tag ANDROID_LOOP=true for ogg files. See issue: http://code.google.com/p/android/issues/detail?id=1314
As for temporarily modifying the tag, I don't know how you could go about doing that.
I haven't tested it but I believe other sound formats don't exhibit this behavior (e.g. mp3 or wav). Perhaps you could convert the ogg files to a different format and keep them as temp data (might help with this: Java - Convert ogg to mp3) This of course seems like a lot of overhead to play back some files, but at least they're usually small files.
