AnimationDrawable lagging

Question

I'm using two voids to make animation because i need diffrent animations in same screen. And this animations for different ImageViews. When i add this two ImageViews at the same time to main screen. They start but lagging. But if i use same animation for diffrent ImageViews there is no problem. Why this lagging happens I use threads to call. Just 2 ImageViews and bitmaps is very tiny and just 3 frames.

EDIT: it was an exported project from eclipse to android studio. I just open new empty project in android studio and copy paste all codes and resources manualy than it just works without any problem.

final RelativeLayout btt = (RelativeLayout) findViewById(R.id.bottomlinear); 

 class MyThread implements Runnable {

                          public MyThread() {
                              ImageView myImage3 ;
                              myImage3 = getimage( 0,btt.getHeight(),700);
                  startAnimation(myImage3);
                              btt.addView(myImage3);
                          }

                          public void run() {
                          }
                      }
