media player - Android: mediaplayer went away with unhandled events -

i need duration of audio file series of voice announcements need play app. have added audio files resources , play fine. sample code below works perfect intended purpose: return duration of audio files.

here code:

float getdurationofaudioresource(locationenum loc, context context){     float  duration = 0;     try {         mediaplayer mp;          mp = mediaplayer.create(context, getaudioresource(loc));         duration = mp.getduration();         mp.release();         mp = null;     }     catch (illegalstateexception e) {e.printstacktrace(); logerror(25, "testdescitem:fault::could not open mediaplayer object audio resource.");}      return duration; } 

here's weird thing. code called in main activity prepares set of audio instructions given test. there no errors within activity. second activity called, long string of errors on logcat.

i've single-stepped upto end of main activity (no errors) , first line of second activity. errors thrown between activities.
also, if comment out 8 lines of try block (thus returning zero) logcat errors avoided. when restore 8 lines errors come back. i've dug through documentation , searched web, , believe correctly constructing, releasing , destroying mediaplayer object, can't see why getting error. said, must doing wrong. ideas?

thanks,

kevin

just put mp.reset(); before mp.release();.
