Android Fatal signal 11 (SIGSEGV) at 0x636f7d89 (code=1). How can it be tracked down?

Question

I\'ve been reading the other posts on tracking down the reasons for getting a SIGSEGV in an Android app. I plan to scour my app for possible NullPointers relate

Answer 1

I got this error when I used ViewTreeObserver inside onDraw() function.

@Override
protected void onDraw(Canvas canvas) {
    // super.onDraw(canvas);
    ViewTreeObserver vto = mTextView.getViewTreeObserver();
    vto.addOnGlobalLayoutListener(new ViewTreeObserver.OnGlobalLayoutListener() {
        @Override
        public void onGlobalLayout() {
            // some animation        
        }
    });
 }
