Android Code Snippet Draw arc with rounded line cap

Using ABExtDrawing lib by @alwaysbusy to draw arc with rounded cap. Android and this lib provides sweep gradient. However the sweep starts from 3:00 direction so may need rotation for certain angles.
Erel has one based on BitmapCreator which is nice as it is B4X, this one is B4A only (B4J version here). Hope it is still useful for someone to make progress bar or knob control view.
