NullPointerException on Falcon.drawRootToBitmap

[mathroule]

When using Falcon with Spoon for instrumentation tests, this exception appears sporadically :

The stack trace:

java.lang.NullPointerException: Attempt to invoke virtual method 'void android.view.View.draw(android.graphics.Canvas)' on a null object reference

I could add the full Spoon trace if needed.

Hi, thank you for reporting this.
Can you please tell me on which device is this happening. It would be nice if you could include the whole test case and I can try to reproduce it.
Please include the Spoon trace as well.

Should be fixed with 0aac416.
It will log an error when the null View in layout manager occurs.

I'm still not sure how this can be possible and if you could provide full test case it might be handy.

I will close the issue when I release new version.
