addArc
addArc is a method in the Android graphics library that appends an arc segment to an existing Path object. The arc is defined by the bounds of an oval and by two angles that determine its start point and sweep length within that oval.
The method signature commonly appears as addArc(RectF oval, float startAngle, float sweepAngle), with an overloaded form
In use, addArc builds a portion of an ellipse defined by the specified oval and places it
Example: path.addArc(new RectF(0, 0, 100, 100), 0, 90) adds a quarter-circle arc starting at the rightmost point
