switch does nothing on Decompiled Android Source

switch(paramMotionEvent.getAction())
{
}
do
{
   for(;;)
   {
      return super.onInterceptTouchEvent(paramMotionEvent);
      this.prevX = MotionEvent.obtain(paramMotionEvent).getX();
   }
}while(Math.abs(paramMotionEvent.getX() - this.prevX) <=this.touchSlop);
return false;
}
}

Hi, I decompiled a few APK files. While analyzing those source code, I found weird lines similar to above code.

Why does the switch do nothing? In addition, I don't know why there is such use for those do - for - while statement. Please tell me something.

Solution

  • Based only on the code posted, it's impossible to say. Most likely you're using a bad decompiler and it gave incorrect output. A lot of the older decompilers aren't very good. Have you tried Procyon or Krakatau?

    Also, if possible, please post the apk you're trying to analyze.
