I've implemented the new Navigation Drawer pattern in an Android app and for some reason it will stick with the 20dp tab preview probably close to 10% of the time.
I've implemented it with a complete copy paste of the demo app so I was surprised not to find anyone else having this issue on SO. Is nobody else seeing this? It happens on both my test devices and I cannot recreate it at all on any of the google apps that have a drawer.
Any ideas of what might cause this? I can paste my code but it's the same as the demo app. The only difference is what I have in my drawer layout (two ListViews and a spinner, but I'm only populating one of the ListViews like the demo app does).
EDIT: This can be recreated consistently in the official demo app.
