[Android-development] QAndroidStyle and qt 5.4.0

Thu Dec 11 20:41:14 CET 2014

Thanks for your reply,

I have tried many sample projects from qt just to be sure it doesn't 
come from mine. For instance Examples/Qt-5.4/widgets/widgets/sliders 
just looks bad (compiled and run out of the box without any change). I 
have uninstall ministro just to make sure it does not interfere, no 
luck. Also tried various android API targets, from 19 to 21, and many 
other desperate ideas...

I will try again tomorrow with a brand new app with just a QPushButton 
and a clean device concerning ministro.

I'm using Android for armeabi-v7a (GCC 4.8, Qt 5.4.0)/Samsung Galaxy 
S4/Android 4.4.2

At least it's good to know it should work :)

Philippe.
