Rotation calling Garbage Collector Too Often Android MatrixMultiply -

-

good day,

i writing open gl app on android. have 100 game objects execute fine when update position, velocity or acceleration. in game loop, want able call "yaw" (or pitch, or roll) method every iteration of update game object. problem causing the garbage collector go crazy gc_concurrent printout statements logcat.

in yaw method, have following calls...

realignvectors(); //no heap allocations in method wrote matrix.rotatem(rotationarray,0,angle,0,1,0); //rotationarray float[16] matrix.setidentitym(rotationalcomputearray,0); //another float[16] matrix.rotatem(rotationalcomputearray,0,angle,upvector.x, upvector.y, upvector.z); matrix.multiplymv(lookvector... matrix.multiplymv(rightvector..

i've commented out code call yaw method , have no calls garbage collector (gc), , 100 objects move through out world out noticable difference. when uncomment out yaw call, significant decrease in performance. objects move choppy , gc calls.

does know if matrix.multiplymv or matrix.rotatem reallocate memory in heap? seams thing guess? if so, know way prevent or fix situation in?

thanks help.

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. 03-07 13:23:43.820: i/actionlogger(21435): gentest_info_test #0 created. 03-07 13:23:43.830: i/actionlogger(21435): gente
