Qt for Android examples

Make sure current examples compile, are relevant and updated.

Create examples that their main target is mobile.

• Filtering Qt Creator list of examples by Android keyword provides examples that don't look and feel like mobile applications but rather desktop ports.

Create more complex examples. Some ideas:

• Maybe create 3 or 4 hero apps
  • Flutter: https://gallery.flutter.dev/
  • Jetpack compose: https://github.com/android/compose-samples

• How to integrate Android native views (e.g. Google Maps)

• Create some applications that showcase multiple Qt solutions at the same time (3D + sensors, efficient lists + networking,...).

• example that showcases how Qt can adapt to different devices. For example, same UI adapts to a laptop, mobile, tablet. (For example, an smart home panel in tablet vs mobile)
