We got the app with Navigation Drawer from support.v4 library. We automating UI testing with Robotium and everything is ok, but Navigation Drawer can freeze randomly so some tests can fail randomly.
This is definitely not a Robotium problem, because I saw how Navigation Drawer gets freezed in some other apps on my device, also in my own apps.
I already tried fix for Navigation Drawer from this question's anwer: Why does DrawerLayout sometimes glitch upon opening?
It helped and random freezes decreased from 90% to about 10%, but 10% of test runs can fail and this is very bad, especially for Continuous Integration...
May be someone already fixed this problem?
