java - Android: get all the notifications by code

Question

I am using some home replacement that allow me to hide the notification Bar and that's something I really like.

All the informations can be replaced by some widgets, but I would like to display the notifications too.

As I already developed some applications, I would like to know if there is a command line that allow an application to get all the notifications. I plan to add this to a widget or a toast.

Thank a lot for any clue or help.

Since Android API Level 18 (Android 4.3) there is a class NotificationListenerService. You must set the Permission BIND_NOTIFICATION_LISTENER_SERVICE and use a intent-filter with the action NotificationListenerService.

 <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>
