How to get notified when a notification is notified

Question

I want to read/access/log the notifications fired on notification bar by other applications.

I searched Intents and PendingIntents a lot, but couldn't get a solution.

Does my application need to be notified when any notification is fired?

Or Does android system provide something to read notifications by the user-level applications?

Starting with api 18 (android 4.3) it's possible: http://developer.android.com/reference/android/service/notification/NotificationListenerService.html

Very easy to use, but the user have to give permission to the app manually.

Finally got the answer.!!! Using AccessibilityService

public class NotificationService extends AccessibilityService {

@Override
public void onAccessibilityEvent(AccessibilityEvent event) {
    // TODO Auto-generated method stub.
//Code when the event is caught 
   }
@Override
public void onInterrupt() {
    // TODO Auto-generated method stub.

}

@Override
protected void onServiceConnected() {
    AccessibilityServiceInfo info = new AccessibilityServiceInfo();
      info.feedbackType = 1;
          info.eventTypes = AccessibilityEvent.TYPE_NOTIFICATION_STATE_CHANGED;
      info.notificationTimeout = 100; 
      setServiceInfo(info);
     }
}

And my Manifest is:

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="org.test.notify"
android:versionCode="1"
android:versionName="1.0" >
<uses-sdk android:minSdkVersion="8" />
<application
    android:icon="@drawable/ic_launcher"
    android:label="@string/app_name" >
     <service android:name=".NotificationService" android:enabled="true">
            <intent-filter >
           <action android:name="android.intent.action.MAIN" />
           <category android:name="android.intent.category.LAUNCHER" />
           <action android:name="android.accessibilityservice.AccessibilityService"/>
        </intent-filter>
     </service>
   </application>
 </manifest>

Enjoy Coding.!!! :)

The code is only to catch events related to notifications. On changing `info.eventTypes = ` we can catch different type of events. — Kishore, Jul 13 '12 at 12:27
i am trying to get log in on service connected method, but it fails, does it require any permissions — Calvin, Feb 21 '14 at 12:36
@Calvin : You need to turn the Accessibility service manually from Settings (Settings -> Acccessibility ) — Kushal, Mar 16 '15 at 13:02

There is not any API for access any notification. At least it would be hole in security. Only thing you can is catching some events, that causes notifications (like sms).

A Notification is raised by sending an Intent.

Intent intent = new Intent(this, NotificationReceiver.class);

The NotificationReceiver catches the Intent and pops up a Notification.

It is perfectly possible to catch the same Intent in one of your applications using a BroadCastReceiver and filter on the Intent you want.

There is no intent for "notification bar state change" or "notification fired". – Kishore Jul 11 '12 at 10:30
That is true, but the notifications are fired using Intents.. And Intents can be caught with a BroadCastReceiver. Afcourse, this all depends on what kind of Nofication you want to access. – DroidBender Jul 11 '12 at 11:15
Actually i want to log all the notifications. So i'm searching for a generic method to catch all the notifications. – Kishore Jul 12 '12 at 11:11

@MartijnVanMierloo : this is not true. notifications are added to the notificationManager, which uses a System service, not a broadcast. – njzk2 Jul 24 '13 at 09:05
