Listen to incoming Whatsapp messages/notifications

Question

I\'m working on a notification based app, for which I need to listen to incoming notifications. I\'ve been able to listen to incoming calls, SMS, mail etc. I have no clue ho

Answer 1

See below example to catch whatsapp notifications:

public class Notifier extends AccessibilityService {


@Override
public void onCreate(){
    //Toast.makeText(this,"Oncreate", Toast.LENGTH_LONG).show();

}

@Override
protected void onServiceConnected() {
    // Set the type of events that this service wants to listen to.  Others
    // won't be passed to this service.
    Toast.makeText(this,"Service connected", Toast.LENGTH_LONG).show();
    AccessibilityServiceInfo info = new AccessibilityServiceInfo();
    info.feedbackType = AccessibilityServiceInfo.FEEDBACK_ALL_MASK;;
    info.eventTypes = AccessibilityEvent.TYPE_NOTIFICATION_STATE_CHANGED ;

    // If you only want this service to work with specific applications, set their
    // package names here.  Otherwise, when the service is activated, it will listen
    // to events from all applications.
    info.packageNames = new String[] {"com.whatsapp"};
    info.notificationTimeout = 100;

    setServiceInfo(info);

}

@Override
public void onAccessibilityEvent(AccessibilityEvent event) {

    if(event.getEventType() == AccessibilityEvent.TYPE_NOTIFICATION_STATE_CHANGED) {

            Toast.makeText(this,"Notification Catched", Toast.LENGTH_LONG).show();
        }

    }
}

And don't forget to set permission from settings>Accessibility in order to access the system events. Allow permission from settings .
