gh-116622: Add Android testbed (GH-117878)

Browse source 
Add code and config for a minimal Android app, and instructions to build and run it.
Improve Android build instructions in general.
Add a tool subcommand to download the Gradle wrapper (with its binary blob). Android
studio must be downloaded manually (due to the license).
