I\'ve got the problem that I need the height of the android tablet system bar. It\'s the same problem as over here, but I cant use this answer, because it gives me the same size
Chris Banes mentioned this in a recent Droidcon talk. The whole talk is super relevant, but here's a link to the part that answers your question (for all form factors, including tablet).

This is the correct way to get status bar and navigation bar sizes: setOnApplyWindowListener
I hope this helps!
