Broadcast Receiver, Notification Android

Question

I have an application using broadcast receiver.

I want to send a notification to the user but sometimes it works, sometimes not. The following code above its my implementation.

MANIFEST.XML

<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED" />      
<application>
    <receiver android:name="com.polifrete.polifreteFunctions.MyReceiver" >
        <intent-filter>
            <action android:name="android.intent.action.BOOT_COMPLETED" />
            <action android:name="android.intent.action.QUICKBOOT_POWERON"/>
        </intent-filter>
    </receiver>
    <service
        android:name="com.polifrete.polifreteFunctions.NotificationService"
        android:launchMode="singleTask" >
    </service>
</application>

SERVICE

package com.polifrete.polifreteFunctions;

import com.polifrete.polifreteandroid.MainActivity;

import android.app.NotificationManager;
import android.app.PendingIntent;
import android.app.Service;
import android.content.Intent;
import android.os.IBinder;
import android.support.v4.app.NotificationCompat;
import android.util.Log;

public class NotificationService extends Service {

public static final int time = 60 * 1000;

@Override
public IBinder onBind(Intent arg0) {
    // TODO Auto-generated method stub
    return null;
}

@Override
public void onCreate() {
    Log.i("Script", "Passou SERVICE CREATE");
    super.onCreate();
}

@Override
public void onStart(Intent intent, int startId) {
    Log.i("Script", "Passou SERVICE START");
}

@Override
public void onDestroy() {
    Log.i("Script", "Passou SERVICE DESTROY");
    super.onDestroy();
}

@Override
public int onStartCommand(Intent intent, int flags, int startId) {
    Log.i("Script", "Passou SERVICE COMMAND");
    final Thread t = new Thread() {
        @Override
        public void run() {
            try {
                while(true){
                    Thread.sleep(time);
                    showNotification();
                }
            } catch (InterruptedException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }
        }
    };
    t.start();
    return Service.START_STICKY;
}

public void showNotification() {

    Intent intent = new Intent(this, MainActivity.class);
    PendingIntent pIntent = PendingIntent.getActivity(this, 0, intent,
            PendingIntent.FLAG_UPDATE_CURRENT);

    NotificationCompat.Builder n = new NotificationCompat.Builder(this)
            .setContentTitle("Test Notification")
            .setContentText("Test Notification.")
            .setSmallIcon(
                    com.polifrete.polifreteandroid.R.drawable.ic_actionbar)
            .setContentIntent(pIntent);

    NotificationManager notificationManager = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);

    notificationManager.notify((int)(Math.random()*10000), n.build());

}

}

BROADCAST

package com.polifrete.polifreteFunctions;

import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.util.Log;

public class MyReceiver extends BroadcastReceiver {

@Override
public void onReceive(Context context, Intent intent) {
    // TODO Auto-generated method stub
    Log.i("Script", "Passou RECEIVER");
    Intent i = new Intent(context, NotificationService.class);
    context.startService(i);
}
}

For the first time after installing the application it will be in disabled state unless it is manually opened by user. So until the application is in disabled state all of the component like service, broadcast receiver and activities will also be in disabled state. Hence your application will not be opened from any external events other then manual intervention. So you need to open the application at least once manually to receive these boot completed intents.
