I faced and win this problem!

In case if you are using AndriodAnnotations here the problem is that I filled the lists in the method onCreate(). I used to get View via findViewById(R.id...) and worked with them.

Now, as it turned out during debugging, all Views is not created in onCreate() yet! The problem was solved when I found an annotation @AfterViews in the docs, and the method under this annotation now fills all my actions and does initialization of fields.

So, anyway, check your code on NullPointerException caused by invoking empty view object.
