Android Read Status Bar Notification | Android Read all incoming notification | Android Read Incoming Sms | Android Read Incoming Call

Hello Friends,
    Today, I am going to share a small tutorial on android "NotificationListenerService"
    which help us to read the all app notifications. This tutorial covers following
    points.

 

Feature:
1. We can easily read the notification of other android application or read all status bar
     notification,
2. Read|Listen incoming whatsapp messages
3. Read all incoming SMS
4. Read all incoming calls
5. Battery Low

Step1 : Create a Notification Service Class :
                    This class extends NotificationListenerService class which contains
                    two method:
                 a) onNotificationPosted(StatusBarNotification sbn) :
                           Implement this method to learn about new notifications as they are
                           posted by apps.
                 b) onNotificationRemoved(StatusBarNotification sbn) :
                           Implement this method to learn when notifications are removed.                         

 Note: The StatusBarNotifcation object contains extras, app package name and
            ticker name

3. AndroidManifest.xml

<?xml version="1.0" encoding="utf-8"?>

4. Android check Notification Access Setting is enable or not:

//check notification access setting is enabled or not
public static boolean checkNotificationEnabled() {
         try{
       if(Settings.Secure.getString(MainActivity.mActivity.getContentResolver(),
                 "enabled_notification_listeners").contains(App.getContext().getPackageName())) 
      {
    return true;
      } else {
         return false;
      }

 }catch(Exception e) {
  e.printStackTrace();
 }
 return false;
}
