With Android P - Api Level 28: You need to get READ_CALL_LOG permission

Restricted access to call logs

Android P moves the CALL_LOG, READ_CALL_LOG, WRITE_CALL_LOG, and PROCESS_OUTGOING_CALLS permissions from the PHONE permission group to the new CALL_LOG permission group. This group gives users better control and visibility to apps that need access to sensitive information about phone calls, such as reading phone call records and identifying phone numbers.

To read numbers from the PHONE_STATE intent action, you need both the READ_CALL_LOG permission and the READ_PHONE_STATE permission. To read numbers from onCallStateChanged(), you now need the READ_CALL_LOG permission only. You no longer need the READ_PHONE_STATE permission.
