As I told, the reason is NOT capture screenshot because it already recycled.
I just know that the reason is: Each call getView(), one instance of convertView is allocated in memory so: flip -> getView() -> create new convertView -> ... -> OOM.

Solution 1: change FlipViewController to use: getViewTypeCount() and getItemViewType() like ListView (more info here http://android.amberfog.com/?p=296)

Solution 2: change YourAdapter to cache some View with different type and reuse View when item have same type.
I'm using solution 2 and when i show log heap size to check the memory, the result is good. And since I used this solution, I have never encountered an OOM error.

Pls try and hope it will help you.

Please refer to #33

Lower the priority of this issue since the memory leak is caused by incorrect handling of adapter in FlipView
