callerNameTextView = view.findViewById(R.id.caller_name_text_view); callerNumberTextView = view.findViewById(R.id.caller_number_text_view); callDurationTextView = view.findViewById(R.id.call_duration_text_view); }

One of the most common bugs in custom ROMs and OEM skins is the "Black Screen of Death"—the screen stays black when a call comes in, or you can't hang up.

@Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_in_call); or you can't hang up.

InCallUI is not the same as your dialer’s main activity. Your dialer app contains the call log and contact search, but the in-call screen is a separate activity that only starts when Telecom broadcasts an InCallService intent.
