How does the app work?

We attach to the onCallStateChanged event provided by the Android System. If the incoming phone number matches an entry you've saved as part of a group, we'll play the ringtone attached to the group. The way we do this:

• Receive Incoming call
• If incoming number is in your contacts list and has a custom ringtone, we play that instead!
• If no custom ringtone, we continue checking for a match
• If match found, we'll play ringtone associated with the Phone Group you've configured
• If no match, we end execution and let Android handle ringtone audio

If we found a match, we actually mute the Ringer audio stream, and use the Alarm audio stream to play the ringtone on repeat. Once the call has ended, we reset the ringer audio stream & alarm audio stream back to their original volume levels and phone resumes normal operation.
