setShadowLayer Android API differences

Question

I develop a custom view component for my application and I am struggling with adding a shadow to a circle.

Here is the code of my class extending View

Answer 1

setShadowLayer() is only supported on text when hardware acceleration is on. Hardware acceleration is on by default when targetSdk=14 or higher. An easy workaround is to put your View in a software layer: myView.setLayerType(View.LAYER_TYPE_SOFTWARE, null).
