I have defined
<item name="android:statusBarColor">@color/some_color</item>
<item name="android:navigationBarColor">@color/some_color2</item>
and it works well in emulator with API 22 but in my Huawei with the same Android version status bar and navigation bar color not works. It remains the same like before.
I can add that another attributes like android:textApperance
or android:background
works fine there is a problem just with those two.
