Add example for modern Android

[r-bird]

The current examples are based on outdated Android code or at least code that hardly anybody is writing in 2021.
There should be at least one example using:

• Kotlin
• Jetpack Compose
  • LiveData
  • a ViewModel
  • a navigation graph
• mavenCentral instead of jcenter
• SDK > 30

And optionally another layout for android smart phones or tablets, so that the app can be used on these devices too.
