Android MediaPlayer error(-1, 4) on prepare()

Question

I have a MediaPlayer instance for local audio files. It worked, but after some changes (bad for me, can't figure out what exactly it was) this error began to appear: //message

Prepare failed.: status=0xFFFFFFFC

//in LogCat

error(-1, 4)
MEDIA_ERROR(mPreparySync) signal application thread

So, what are possible reasons? File to play exists.

Out of the blue i would guess the file format does not fit

I 've gotten this error evertime I've tried to play a non supported file format like wmv. So I'd check that first Check these links: Android MediaPlayer not preparing. Error (1, -4) and MediaPlayer.setDataSource causes IOException for valid file?

Tried .mp3 and .ogg, no luck. Both are supported. – Pavel Oganesyan Oct 22 '12 at 18:56

Check the file path first, make sure you have a valid Uri. An other reason would be that you instanciate to many players.
