Possible Solution

I had this same issue. I setup an animation and in onAnimationEnd I was removing the object that had been animated which is when problems started. What I did was setup an asynchronous Runnable to wait 100 milliseconds after the animation had stopped before removing the animated object:

the object previously animated is this._loader

private void removeLoader() {    final ContentContainer self = this; // "CustomContainer" needs to match the type of `this`    Handler h = new Handler();    h.postAtTime(new Runnable() {        @Override        public void run() {            MainActivity.instance.runOnUiThread(new Runnable() {                 @Override                public void run() {                    try {                        if(self._loader == null) {                            // there is no loader. quit now while you still have the chance!!                            return;                        }                        while(self._loader.getParent() != null) {                            removeView(self._loader);                        }                    } catch(Exception e) {                        Crashlytics.logException(e);                        e.printStackTrace();                    }                    self._loader = null;                }            });        }    }, 100);}

Cheers

I was facing same problem. I resolved with Handler.

new Handler(Looper.getMainLooper()).post(new Runnable() {                @Override                public void run() {                   // remove fragment from here                }            });

The problem is in the ViewGroup's dispatchDraw() method. This method tries to draw all the ViewGroup's children. When a child is null, you get an exception, which most likely comes from this line: if ((child.mViewFlags & VISIBILITY_MASK) == VISIBLE) { (notice the mViewFlags).

So the problem is that one of your views, somewhere, is not properly initialized. I'm afraid that's the best I can do.
