[Interest] icons color on Android Wear

[maitai]

Hi all,
I am writing a small QML app for Android Wear (Qt 5.11.1, Android 4.4W 
but I have also tried with 8.0, same issue).

The problem is that all icons appear "inverted", i.e black color become 
white. The same app running on desktop or "regular" Android shows the 
icon as they should. This occurs on a real device or with an ADB 
emulator. This is can be easily reproduced with the Wear app example 
provided with Qt. Icons are in a QML RoundButton.

Can it be somehow a pb with a style, or does someone knows what could 
trigger such a behavior?

Thanks
Philippe.
