That in deed is a nice approach. I wasn't aware that android has such a drawable. To abd this is more a 'ring' shape than a filled circle, but I guess a ring is also acceptable. But can you give me a hint how to control the 'progress' in the java code? So that I can i.e. increase it fluently in a timer or indicate a progress in downloading a file.
