How to include screenshot like "Send Feedback" activity in Google+

I want to create an activity similar to the "Send Feedback/Report and Issue" page on Google+. Is there an api to capture the screenshot, or is this 开发者_JAVA百科manufacturer dependent?

There is currently no exposed API for accessing the screen buffer. You may find some success in using View.getDrawingCache(boolean) which returns a Bitmap of the View which you may then be able to save and use.
