Android SDK

The website currently states the Java SDK is currently not available due to the Java 8 dependency.
This now no longer seems to be true due to the Java 8 desugaring support

The current SDK seems to work correctly with Android though (using SDK 26+)

It might be helpful to add some integration docs though for Android defining the ProGuard / R8 rules required to run the project plus the minimum required Android version (and other helpful info?).

Having a dedicated Android SDK as some point in the future like Swift / iOS has would be even better as that could take care of stuff like storing the access token(s) on device for a persistent sessions or handing of anonymous sessions which now seems to be something that has to be configured manually.

Beginnen Sie mit der Überprüfung der Aussage auf der Website zur Android-Verfügbarkeit von Java SDK sowie der verlinkten Dokumentation zu Java-8-Desugaring und SDK. Ermitteln Sie die unterstützte Android-Version und alle erforderlichen ProGuard- oder R8-Konfigurationen. Aktualisieren Sie anschließend die Integrationsanleitung, sodass die dokumentierte Android-Unterstützung dem aktuellen SDK-Verhalten entspricht.
