I installed Android L today and checked it. Everything seems working to me. I had no exceptions. You know L is not reliable yet. So this problem may not be library's problem, may be caused by L.

[capur16]

On nexus 5 with stable android L, I have same exception.

[eluleci]

Since that L Preview is not a stable version these kind of errors may happen and it is not the problem of the library. I am closing this issue because Lollipop is released and there is no such error in that stable version.

[michalbrz]

I have the same problem with official Lollipop 5.0.1. Just created a sample app to try if this is really a problem with Android L or my own project. Only creating auto-generated app and adding FlatUI's SeekBar works. BUT when you change project's theme to some theme from latest AppCompat (v7), for example Theme.AppCompat.Light.NoActionBar, then exception occurs. So FlatUI doesn't play well with AppCompat.

There is the same issue on Xperia Z3 with android L. Do you have any idea how to fix that ?

The same issue on sony z3 android 5.0.2
