Try to integrate NDK builds or follow up on the continuous suggestions given at any major Android conference about how to speed up builds.
That basic boilerplate is no longer enough and tricks change with each release.

My Android projects are mostly private stuff but I don't remember any project that would require any kind of custom build. There is whole plethora of tools. My own calculators for various stuff, app to communicate with my family, apps to manage my electronics (bluetooth, wifi, cloud), apps to manage stuff in my Drive. My changes are mostly adding dependencies.
