I don't like the android style plugin, can I switch back to the old one?
Yes you can. There are two options way to do it:
- if you want to use the old plugin with the android palette and fonts, then AFTER you create the application object set the style to plastique: QApplication::setStyle(new QPlastiqueStyle);
- if you want to disable the new plugin completely (no palette and fonts) then you have edit the QtActivity.java and set QT_USE_ANDROID_NATIVE_STYLE environment variable to 0.
