Reading enter link description here, it looks like fb0 has restricted permissions for security reasons -- were permission not closed an app could spy on user activities outside a given app. Your app won't programmatic have access to it, on non-rooted phones anyway. If you need screen shots of your app, the usual approach is to get a bitmap from a parent layout in your app using this pattern. That is allowed.
