[Android-development] No more android native style for QtWidgets in 5.12.1?

[Mariella Squillante]

Hello everyone,

I've used until now Qt 5.6.2 for my QtWidgets (multiplatform) android 
app, and widgets were automatically styled with native android style.

Now I've updated to Qt 5.12.1, to be able to compile for arm64, and now 
widgets are no longer styled, they appear like desktop app and are too 
small for a touch system.
I've already searched the web with no luck, so I'm asking here...

What happened?
