问题
I'm working in React Native Application. I'm trying hard in Android to make use of Notification Services & BIND_NOTIFICATION_LISTENER_SERVICE. I'm trying to read the incoming notifications using NotificationListenerService.
I'm using One Plus 5T (Android Oreo) for debugging.
I've seen lots of duplicate questions and I've tried the following solutions which I got from those questions.
1.Restarting the phone (Sounds silly and it doesn't work)
2.Re-install/Re-build the application
- Renaming the NotificationListenerService class file and run Etc..
Problems I've been facing,
1.Cannot see my application in 'Notification Access' settings.
2.onCreate / onNotificationPosted is not getting called when I receive any Notification
3.Checked whether my application is having Notification permisson or not using the below code and it returned 'false' (Obviously, that's my problem)
ComponentName cn = new ComponentName(getReactApplicationContext(), NotificationListener.class);
String flat = Settings.Secure.getString(getReactApplicationContext()
.getContentResolver(), "enabled_notification_listeners");
final boolean hasPermission = flat != null && flat.contains(cn.flattenToString());
// hasPermission - false
Since BIND_NOTIFICATION_LISTENER_SERVICE is not listed Dangerous permissions list, I thought defining it in Manifest (Source is given below for your reference) is enough instead of asking run time permission.
I've followed this tutorial and referred other tutorials also. I can't find out where I'm doing wrong. Everything looks perfect. After scratching my mind for the whole day, I thought I'd ask your help.
Find my source code below.
Your time and patience are appreciated. (:

AndroidManifest.xml

String pack = sbn.getPackageName();
String ticker ="";
if(sbn.getNotification().tickerText !=null) {

}

}

Log.i(TAG, "********** onNOtificationRemoved");

// Registering Receiver
LocalBroadcastManager.getInstance(mainContext).registerReceiver(myReceiver, new IntentFilter("NOTIFICATION_POSTED_KBT"));
// Check Notification Permission in our app

This is weird but I've got it successfully running the next day after doing the following things very carefully (Without skipping any steps)
Uninstall the Application
Stop/Close react native server
Renaming the
NotificationListenerServiceclass fileReconnect the USB cable (If not simulator) and change Connect type from
Charge onlytoMedia TransferBuild your android code
Execute
react-native run-androidPray God _/\_ (Just kidding, but it helps though)
Best of luck.
