I have a custom view which is simulating the rotation of a ball with some text.

To achieve this, my custom view( which extends RelativeLayout) is overriding the onDraw method:

protected void onDraw(Canvas canvas) {

    super.onDraw(canvas);

    mCirclePath.reset();

    mCirclePath.addCircle(canvas.getWidth() / 2, canvas.getHeight() / 2, mRadious, Path.Direction.CW);

    canvas.drawCircle(canvas.getWidth() / 2, canvas.getHeight() / 2, mRadious, mBackGroundPaint);

    canvas.drawPath(mCirclePath, mBackGroundPaint);

    canvas.clipPath(mCirclePath);

    canvas.drawColor(Color.TRANSPARENT);

}

This way I'm cropping everything outside of the bitmap circumference, allowing me to move the text inside the layout. this + rotating the text simulates the ball rotation in fake 3d.

My solution works fine in Android 4,5,6 and 9, but somehow it's not working in 7 and 8.

Here is a very simplify version of my animation with just the view rotation part:

ObjectAnimator anim =  ObjectAnimator.ofFloat(this, View.ROTATION, 0, 190);

anim.setDuration(6000);

In Android 7 and 8 it seems like the bitmap and the text view are rotating but the container remains static. this works perfectly in other android versions...

I already tried moving the camera position wit no success.

Edit1: So after messing around for a while i found that the culprit is clipPath, somehow this conflicts with the Object animator rotation. the "solution" i found for now, is setting the LayerType to View.LAYER_TYPE_SOFTWARE. But i'm not happy with this solution because since this is a composite view, and I'm animating the text at the same time, the layer is going to keep invalidating...
