loops - Android fixed delta time still choppy? -


below game loop , logcat output. game runs bit choppy , noticed in logcat gc running every often. i'm not quite sure if gc or delta time causing this? can try point me in right direction based on info provided?

@override public void run() {      canvas canvas;     while (isrunning) {         if (!gamepanel.paused) {             canvas = null;             try {                 startdraw = system.currenttimemillis();                 canvas = surfaceholder.lockcanvas();                 synchronized (surfaceholder) {                     gamepanel.update(deltatime);                     gamepanel.draw(canvas);                 }             } {                 if (canvas != null) {                     surfaceholder.unlockcanvasandpost(canvas);                     enddraw = system.currenttimemillis();                     mylogger.getinstance().log(                             "delta time = " + (enddraw - startdraw)                                     / 1000.f);                 }             }              deltatime = (enddraw - startdraw)                     / 1000.f;          }     } }  -09-04 15:59:29.855: d/dalvikvm(3273): gc_for_alloc freed 4427k, 35% free

shujima pheonix right --- although won't lot, in looping, things can pile up. draw called fast , frequent, , looper too, when this: 

  mylogger.getinstance().log(                              "delta time = " + (enddraw - startdraw) / 1000.f);

what is:

add 2 floats , divide result, take result , convert string. (maybe copy ?) string , append string "delta time = ", (maybe?) copy combined string again parameter passed .log() <- of you've gotten new instance of every time. far amount of overhead when in rapid loop ...
