android java mediaplayer Service - how can I know if mediaPlayer is prepared?

问题

I made a binded service with MediaPlayer controls which loads and play back audio. But as it happens, sometimes mediaPlayer.prepare(); is not fast enough and it's not always prepared to playback.

So how can I make such method , something like myService.prepare() where I can ask for MediaPlayer to prepare and wait for it?

回答1:

You may wait for the OnPrepared event to be triggered by the MediaPlayer.

Edit : prepare() is blocking only for files, so if you're working with something else, that might be the cause.
