In my app (with AppCompat-v7) it happens sometimes that, after the sliding touch to request the Navigation Drawer, the drawer locks at the beginning of the passage: it appears only partially and DrowerToggle's animated icon remains crooked. What may be due? Thanks
EDIT 1: it seems that this behavior of the drawer happens in coincidence with the simultaneous request to execute a AsyncTask which will then update the UI from onPostExecute. Does anyone have an explanation?
EDIT 2: I found this Why does DrawerLayout sometimes glitch upon opening? very similar question.
I tried the suggested solution with android:clickable="true" on the main parent ViewGroup, except the DrawerLayout, of Activity: it works for the majority of cases but not all, and I can not explain how the frequency of the problem is directly related to the intensity of the updates on the UI.
Perhaps both affect: android:clickable="true" on the main parent ViewGroup accelerates the response upwards with respect to the management of TouchEvent by Navigation Drawer, while a lower activity of updating the UI promotes proper cancellation of PostDelayed sent to the UI from the same Navigation Drawer in case of crossing the touch slop.
