Hello,
Checkboxes and radiobuttons styles are broken when running on an Android 9 device, using Qt 5.12.3 armV7 or x86 (not tested with armv8). Many errors reported in the console, related I guess to extracting Android style. Same program compiled with GCC/Qt 5.11.1 runs fine. Same program compiled with CLANG/Qt 5.12.3 and running on Android 8.0 runs fine. So the problem is with Android 9 and CLANG/Qt 5.12.3.
I join a small project reproducing the issue, the console log and a screenshot. Note that besides the layout issue, the checked status also does not show anything, for both radiobuttons and checkboxes.
Since we are obliged by Google to support 64 bits builds before August 2019 and only Qt5.12+ supports it, this is clearly important for us.
Thanks for fixing this, clock is ticking.
