As part of the Android 8.0 (API level 26) Background Execution Limits, apps that target the API level 26 or higher can no longer register broadcast receivers for implicit broadcasts in their manifest. you can register your receiver dynamically in Activity by calling registerReceiver(new CallReceiver(), new IntentFilter().addAction("android.intent.action.PHONE_STATE")); also, a bad thing about this approach is your receiver will only work when your app is in the foreground. If you close your app then you don't trigger any broadcasts in background. also, refer this if you are looking for call log data.
