Hello. I am trying to use MediaPlayer to play background sounds for
my game. I have currently been using as follows, but my application
has been crashing and I can only attribute it to my implementation of
MediaPlayer. I would like to use only 1 MediaPlayer Object, but I'm
starting to think that it's crashing because I'm not releasing the
resources from the MediaPlayer. But, once I call release() on the
mediaplayer object, it doesn't seem like I can play it again. So I'm
stuck in this predicament in how to implement the MediaPlayer to play
background sounds for my game. The current implementation sort works,
but crashes after some indeterminate amount of time, with a native
crash dump (even though I'm writing all java code).
How can I efficiently use the MediaPlayer to play background sounds.
It seems wrong to 'new' a MediaPlayer for each sound that I have. Is
this really the way to go?
How can I do this?
Thanks in advance
