Hi all,

I'm trying to catch notifications of other apps in my project (like 'floating notifications'
playstore Link: https://play.google.com/store/apps/details?id=robj.floating.notifications
compiled a java/B4A-library successfull with snippets from Stackoverflow:

java code:
B4X: 
package de.esolutions4you.bubblelauncher.notificationservice;

import anywheresoftware.b4a.BA.Author;
import anywheresoftware.b4a.BA.Permissions;
import anywheresoftware.b4a.BA.ShortName;
import anywheresoftware.b4a.BA.Version;
import anywheresoftware.b4a.BA;

import android.accessibilityservice.AccessibilityService;
import android.accessibilityservice.AccessibilityServiceInfo;
import android.view.accessibility.AccessibilityEvent;

@Version(1.6f)
//@Permissions(values={"android.permission.INTERNET"})
@ShortName("NotificationService")
@Permissions(values = {"android.permission.BIND_ACCESSIBILITY_SERVICE"})
//@DependsOn(values={"some java library "})
//@ActivityObject

public class NotificationService extends AccessibilityService {
  
  

    @Override
    public void onAccessibilityEvent(AccessibilityEvent event) {
       System.out.println("onAccessibilityEvent");
       if (event.getEventType() == AccessibilityEvent.TYPE_NOTIFICATION_STATE_CHANGED) {
           System.out.println("notification: " + event.getText());
       }
    }


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


    @Override
    public void onInterrupt() {
      System.out.println("onInterrupt");
    }

}

created an accessibilitymetadata.xml file:

XML:
B4X: 
<?xml version="1.0" encoding="utf-8"?>
<accessibility-service xmlns:android="http://Schemas.android.com/apk/res/android"
    android:accessibilityEventTypes="typeNotificationStateChanged"
    android:accessibilityFeedbackType="feedbackAllMask"
    android:notificationTimeout="100" />

I want to use a service, so I defined the following in manifest.xml:

B4X: 
               <service
                   android:name=".notificationservice"
                   android:permission="android.permission.BIND_ACCESSIBILITY_SERVICE" >
                   <intent-filter>
                       <action android:name="android.accessibilityservice.AccessibilityService" />
                   </intent-filter>
    
                   <meta-data
                       android:name="android.accessibilityservice"
                       android:resource="@xml/accessibilitymetadata" />
               </service>

I can add the coompiled ba4Lib to my Project and can see the voids.

I see now my app under system settings -> accessibility.
and can activate my app...


But I have now idea, how I can initialize / use the lib in my project?
- making a wrapper?
- bind otherwise ?


If somebody could help here please?

thanx and regards

Start with adding some Common.Log messages to this library to see that it is working. Once it is working you should pass a BA object to this service and call ba.raiseEvent to raise events from the service. You can use a static variable to pass the BA object to the service.

Hi Erel,

thank you for giving me a direction to step in...

BTW - is there any option in the commununity Forum - to edit typos in Threads title? :)
