创建后台 android 服务以拒绝来电

Question

looking for resources on how to create an ongoing background service started by an android app which declines/silences and logs incoming phone calls. This must not use deprecated APIs/permissions for Android 10.

Answer 1

A way to decline an incoming call is to hang up the call but permissions are needed. Try to follow this (this is the concept):

1. Request Run time permissions(READ_PHONE_STATE, CALL_PHONE)

2. Create a broadcast receiver that waits for incoming calls

3. When incoming call is detected hang it up.
