An Android app that rejects calls from numbers matching various conditions.

Issues

- On Android versions before Q (API 29), the app does not always get notified about incoming calls in time to reject them before the ringer starts. This is fixed in Q with the CallScreeningService API.
- On Android versions before Lollipop (API 21), the app must run as a system app to block calls.
