How to observe Android's Clipboard, really ?

Question

I need to detect Android Clipboard's content changes, and register the changes, but I can't really understand how to achieve such result.

There are a lot of clipboard managers around, but I found none open source, and it's difficult to believe they work by checking the clipboard every 15 seconds.

Is there a good method to observe clipboard changes ?

Thanks in advance !

Answer 1

According to this thread, at least for the Clipper program, they do indeed poll the clipboard - every 5 seconds. There doesn't seem to be anything in the API to do it any other way.
