Call Filter

An Android app to reject calls from numbers matching various conditions.

Build

Use Android Studio

Issues

• On Android versions before Q (API v29) the app does not always get notified about a call to reject it before the ringer can start. This is fixed in Q with the CallScreeningService API.
• On Android versions before Lollipop (API v21) the app must run as a system app to block calls.
