Capture users signature in an Android app [closed]

It's difficult to tell what is being asked here. This question is ambiguous, vague, incomplete, overly broad, or rhetorical and cannot be reasonably answered in its current form. For help clarifying this question so that it can be reopened, visit the help center开发者_C百科. Closed 9 years ago.

My requirement is to make an activity which provides user with a screen in which user can input his signs. I want these signs to be then saved as an image in database. Is there any default activity which does similar task.

There is no "default activity" designed to capture a signature, sorry.
