      When using the Material style on Android, if you update the enabled state of a Button in the onPressed handler the application will crash with:

      F libc : /Volumes/Android/buildbot/src/android/ndk-release-r21/external/libcxx/../../external/libcxxabi/src/abort_message.cpp:72: abort_message: assertion "Pure virtual function called!" failed

      This only seems to happen for the Android target. If you use the Material style on the macOS target it works ok.

      I have attached a sample project that reproduces the issue. To run:

      1. Build and run using Qt 5.15.0 for Android
      2. Tap multiple times on the "Press Me" button.
