Android Read Status Bar Notification | Android Read all incoming notification | Android Read Incoming Sms | Android Read Incoming Call

Hello Friends,
    Today, I am going to share a small tutorial on android "NotificationListenerService"
    which help us to read the all app notifications. This tutorial covers following
    points.

 




Feature:
1. We can easily read the notification of other android application or read all status bar
     notification,
2. Read|Listen incoming whatsapp messages
3. Read all incoming SMS
4. Read all incoming calls
5. Battery Low

Step1 : Create a Notification Service Class :
                    This class extends NotificationListenerService class which contains
                    two method:
                 a) onNotificationPosted(StatusBarNotification sbn) :
                           Implement this method to learn about new notifications as they are
                           posted by apps.
                 b) onNotificationRemoved(StatusBarNotification sbn) :
                           Implement this method to learn when notifications are removed.                         

 Note: The StatusBarNotifcation object contains extras, app package name and
            ticker name

1. NotificationService.java

package android.notifications;

import android.app.Notification;
import android.content.Context;
import android.content.Intent;
import android.graphics.Bitmap;
import android.os.Bundle;
import android.service.notification.NotificationListenerService;
import android.service.notification.StatusBarNotification;
import android.util.Log;
import android.support.v4.content.LocalBroadcastManager;

import java.io.ByteArrayOutputStream;

    Context context;

    @Override

    public void onCreate() {

        super.onCreate();
        context = getApplicationContext();

    }
    @Override

    public void onNotificationPosted(StatusBarNotification sbn) {
        String pack = sbn.getPackageName();
        String ticker ="";
        if(sbn.getNotification().tickerText !=null) {
            ticker = sbn.getNotification().tickerText.toString();
        }
        Bundle extras = sbn.getNotification().extras;
        String title = extras.getString("android.title");
        String text = extras.getCharSequence("android.text").toString();
        int id1 = extras.getInt(Notification.EXTRA_SMALL_ICON);
        Bitmap id = sbn.getNotification().largeIcon;


        Log.i("Package",pack);
        Log.i("Ticker",ticker);
        Log.i("Title",title);
        Log.i("Text",text);

        Intent msgrcv = new Intent("Msg");
        msgrcv.putExtra("package", pack);
        msgrcv.putExtra("ticker", ticker);
        msgrcv.putExtra("title", title);
        msgrcv.putExtra("text", text);
        if(id != null) {
            ByteArrayOutputStream stream = new ByteArrayOutputStream();
            id.compress(Bitmap.CompressFormat.PNG, 100, stream);
            byte[] byteArray = stream.toByteArray();
            msgrcv.putExtra("icon",byteArray);
        }
        LocalBroadcastManager.getInstance(context).sendBroadcast(msgrcv);


    }

    @Override

    public void onNotificationRemoved(StatusBarNotification sbn) {
        Log.i("Msg","Notification Removed");

    whole day spent on this n finally got your post

    thanx for this post.


    but if i want to store these notifications in array or a varaible instead of listview, will it be possible, if yes kindly share the answer plz...

    ReplyDelete
    Replies
    1. Yes you can make Arraylist of Model class where you can store the data. I don't know your exact requirement but what i suggest is storing the model class data in DB is a best way.
