How to read all the coming notifications in android

Question

How to read all the coming notifications in android. Is it possible to use the broadcast receiver to listen the incoming notifications and the ability to read the notifications information.

You can have a look at the AccessibilityService, see http://developer.android.com/training/accessibility/service.html#create or http://stackoverflow.com/questions/14540394/listen-to-incoming-whatsapp-messages-notifications — Robe Elckers, May 26 '13 at 09:30

First you must declare your intent to receive notifications in your manifest, so that you can get the android.permission.BIND_NOTIFICATION_LISTENER_SERVICE permission.

AndroidManifest.xml:

<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>

Then create a NotificationListenerService class and override the onNotificationPosted function.

For more information, read the developer reference here: https://developer.android.com/reference/android/service/notification/NotificationListenerService.html

Also look at this simple example application for implementation guidance: https://github.com/kpbird/NotificationListenerService-Example/

You need to do like this in onNotificationPosted in order to get all messages

if ((Build.VERSION.SDK_INT >= Build.VERSION_CODES.N)){
        Parcelable b[] = (Parcelable[]) extras.get(Notification.EXTRA_MESSAGES);

        if(b != null){

            for (Parcelable tmp : b){

                Bundle msgBundle = (Bundle) tmp;
                content = content + msgBundle.getString("text") + "\n";

            /*Set<String> io = msgBundle.keySet(); // To get the keys available for this bundle*/

            }
        }
    }
