What is the expected behavior? I expect it to take and save the screenshot Any other comments?

What versions of software are you using?

Looks like your view is null when you are trying to take the screenshot. Make sure you have the view available of which you take the screenshot of.

java.lang.NullPointerException: Attempt to invoke virtual method 'void android.view.View.measure(int, int)' on a null object reference
at github.nisrulz.screenshott.ScreenShott.takeScreenShotOfJustView(ScreenShott.java:98)

I don't think it's a problem of the fragment itself. Could you share a barebone implementation where the lib crashes because its been called inside a fragment? I would make sure that its being called once the view is created and then try to take the screenshot.
