Erasing via circle

[engrnawaz]

I want when i touch on screen then a colored circle will appear in the erasing point and when a move or start erasing then the circle will also move with the finger and erasing will also perform using this library.
Give me any suggestion or relevant example.

One Idea is use the native Android feature...

Enable

Settings.System.putInt(context.getContentResolver(),"show_touches", 1);
Disable

Settings.System.putInt(context.getContentResolver(), "show_touches", 0);
