Securely Building any Android App from Source

The F-Droid project is automatically building a large number of 3rd party Android applications from source. The various combinations of the Android SDK, NDK and gradle versions as well as app dependencies can easily exceed 60G in size. Therefore, a secure and adaptive caching strategy is needed to share common requirements without exposing the builds to untrusted dependencies.
