NotificationListenerService not connecting to notification manager

Question

I'm having trouble creating a service which extends android.service.notification.NotificationListenerService

As per https://developer.android.com/reference/android/service/notification/NotificationListenerService.html I have added the following to the manifest:

<service android:name=".NotificationListener"
 android:label="@string/service_name"
 android:permission="android.permission.BIND_NOTIFICATION_LISTENER_SERVICE">
        <intent-filter>
            <action android:name="android.service.notification.NotificationListenerService" />
        </intent-filter>
</service>

I override Service#onStartCommand:

@Override
public int onStartCommand(Intent intent, int flags, int startId) {
    Log.d(TAG, "Got onStartCommand");
    return super.onStartCommand(intent, flags, startId);
}

and NotificationListenerService#onListenerConnected:

@Override
public void onListenerConnected() {
    Log.d(TAG, "Got onListenerConnected");
}

When I run, though, starting the service with an explicit intent, I see that onStartCommand runs but not onListenerConnected. If I try and run requestInterruptionFilter(NotificationListenerService.INTERRUPTION_FILTER_NONE), from onStartCommand (which is what I want to do) I get W/NotificationListenerService[NotificationListener]: Notification listener service not yet bound.

Any idea why I'm not getting onListenerConnected () (and thus can't send requestInterruptionFilter)?

This is on Lollipop 5.1.1 on Xperia Z1 compact.

Answer 1

1. Open Settings app
2. Sound & notification
3. Notification access
4. Your service name should be listed in this screen.
5. Check mark beside your service name
