Cordova Android Push Plugin

I am trying to create push notification for my cordova project. I followed the tutorial from this link http://devgirl.org/2012/10/25/tutorial-android-push-notifications-with-phonegap/ and created the plugin and I see the FCM is not sending back the registration id. I have added sender id in my application. Please help me to get this done. Thanks in advance.

BroadCast Receiver makes slowly works to other services

when I listen push message from BroadcastReceiver I can take message but it makes slow other services for example I am sending "Message is taken" to my web service when I take push message but I can't send to my webservice it works very slowly when I listen to BroadcastReceiver for take message and when I delete BroadcastReceiver I can send message to my webservice very fastly

Problem is: The broadcast receiver that you are registering is implemented on the Main thread. The broadcast receiver handler is ALWAYS EXECUTED ON THE MAIN THREAD, thus, making your entire process slower. To implement receiver's own thread, you can explicitly do so by providing it's own Handler thread.
Register your broadcast receiver like this:
HandlerThread receiverHandlerThread = new HandlerThread("threadName");
receiverHandlerThread.start();
Looper looper = receiverHandlerThread.getLooper();
Handler handler = new Handler(looper);
context.registerReceiver(mHandleMessageReceiver,newIntentFilter(DISPLAY_MESSAGE_ACTION),null,handler);

How to make notification appear only in top?

So I have this code
public class notif extends Activity {
private static final int NOTIFY_ME_ID=1337;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
final NotificationManager mgr=(NotificationManager)this.getSystemService(Context.NOTIFICATION_SERVICE);
Notification note=new Notification(R.drawable.icon,"New Problem ",System.currentTimeMillis());
note.flags|=Notification.FLAG_AUTO_CANCEL;
PendingIntent i=PendingIntent.getActivity(this, 0,new Intent(this,list.class), 0);
note.setLatestEventInfo(this,"Problem Occured","Click to see the problem",i);
mgr.notify(NOTIFY_ME_ID,note);
}
This code is about making notifications but i want it to just appear on my notification on top an not opening any page at first so it's like the notification can appear in the main menu without opening any page at first like.the sms notification that appear on top only without having to see the entire sms until we click the notification so can someone help me with this? :)

Create a class NotificationAlert and paste the code below there:
import android.os.Bundle;
import android.app.Activity;
import android.app.Notification;
import android.app.NotificationManager;
import android.app.PendingIntent;
import android.content.Context;
import android.content.Intent;
public class NotificationAlert extends Activity {
private static final int NOTIFY_ME_ID=1337;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.notification_alert);
/*********** Create notification ***********/
final NotificationManager mgr=
(NotificationManager)this.getSystemService(Context.NOTIFICATION_SERVICE);
Notification note=new Notification(R.drawable.stat_notify_chat,
"Android Example Status message!",
System.currentTimeMillis());
// This pending intent will open after notification click
PendingIntent i=PendingIntent.getActivity(this, 0,
new Intent(this, NotifyMessage.class),
0);
note.setLatestEventInfo(this, "Android Example Notification Title",
"This is the android example notification message", i);
//After uncomment this line you will see number of notification arrived
//note.number=2;
mgr.notify(NOTIFY_ME_ID, note);
}
}
Create a class NotifyMessage and paste the code below there:
import android.app.Activity;
import android.os.Bundle;
import android.widget.TextView;
public class NotifyMessage extends Activity {
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
TextView txt=new TextView(this);

Why isn't it working?

Probably the most common source of binding silently failing is not having the service listed in the manifest. This does not raise an exception, so your app does not crash, but there should be a message (warning, IIRC) in LogCat pointing out your issue.
