If you haven’t yet compiled any application for Android, now is the best time!

1. First of all, our [documentation how to setup Android tools and build your first Android application](https://castle-engine.io/android) is now much shorter and easier to follow. It properly documents now:

2. Android building now works with latest [Java 17](https://www.oracle.com/java/technologies/downloads/). No need for downgrading to older Java, because older Gradle wrapper couldn’t handle it.

3. The default Android target platform is now 31. Previously we targeted platform 29. Due to [Google Play requirements](https://developer.android.com/google/play/requirements/target-sdk) we had to upgrade to 30, and we decided to take it one step further to 31. (required by latest `androidx.core`).
