Not receiving Firebase cloud push notifications in Android app

I am not receiving push notification for my app. I have included the manifest files, the MainActivity file, the MyFireBaseMessagingService file and the build.gradle file and the googl-services.json. I really am stumped on what the issue could be. I go to Firebase composer to write message but nothing is received. I can hard code values in strings file and I receive a notification but I wanted something more dynamic. That is why I am trying to figure out how to send push notifications from FCM but I seem to be missing something or inputting something incorrectly.

I've had a similar issue. I've tried everything - in my opinion the main reason is that all the services are, sooner or later, being killed by the system. The only way is to make sure to deliver the notification to the system tray not to the application. To do that you need to use Data message notifications.
There are 2 types of FCM notifications: Notification message and Data message.
Data messages are delivered to system tray and are always display - even if service is not running.
Notification message looks like:
{
"message":{
"token":"bk3RNwTe3H0:CI2k_HHwgIpoDKCIZvvDMExUdFQ3P1...",
"notification":{
"title":"Portugal vs. Denmark",
"body":"great match!"
}
}
}
and triggers method OnMessageReceaved() of FirebaseMessagingService. Many devices (especially Huawei and Xiaomi) try to do everything to kill background services to prevent battery drain. So the FirebaseMessagingService isn't the best way to handle notifications.
Second type is Data message:
{
"message":{
"token":"bk3RNwTe3H0:CI2k_HHwgIpoDKCIZvvDMExUdFQ3P1...",
"data":{
"Nick" : "Mario",
"body" : "great match!",
"Room" : "PortugalVSDenmark"
}
}
}
This type is handled by the system tray, so you don't need any of service running to get the notification. Its much more convenient method, but as far i know, it can't be achieved with the console.
You would probably need server API to send Data message.

Firebase Push Notifications does not receive

I'm trying firebase push notification. I did everything it said in the tutorial, but it isn't working.
FirebaseMessagingService:
package com.example.firebasenf.firebasenf;
import com.google.firebase.messaging.FirebaseMessagingService;/
public class MyFirebaseMessagingService extends FirebaseMessagingService {
}
FirebaseInstanceIdService:
package com.example.firebasenf.firebasenf;
import com.google.firebase.iid.FirebaseInstanceIdService;
public class MyFirebaseInstanceIDService extends FirebaseInstanceIdService {
}
Manifest:
<service
android:name=".MyFirebaseMessagingService">
<intent-filter>
<action android:name="com.google.firebase.MESSAGING_EVENT"/>
</intent-filter>
</service>
<service
android:name=".MyFirebaseInstanceIDService">
<intent-filter>
<action android:name="com.google.firebase.INSTANCE_ID_EVENT"/>
</intent-filter>
</service>

you need to add some methods to your code :
FirebaseMessagingService:
package com.example.firebasenf.firebasenf;
import android.app.NotificationManager;
import android.app.PendingIntent;
import android.content.Context;
import android.content.Intent;
import android.support.v4.app.NotificationCompat;
import com.google.firebase.messaging.FirebaseMessagingService;
import com.google.firebase.messaging.RemoteMessage;
public class MyFirebaseMessagingService extends FirebaseMessagingService {
#Override
public void onMessageReceived(RemoteMessage remoteMessage){
Intent intent = new Intent(this,MainActivity.class);
intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
PendingIntent pendingIntent = PendingIntent.getActivity(this,0,intent,PendingIntent.FLAG_ONE_SHOT);
NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(this);
notificationBuilder.setContentTitle("Application Title");
notificationBuilder.setContentText(remoteMessage.getNotification().getBody());
notificationBuilder.setAutoCancel(true);
notificationBuilder.setSmallIcon(R.mipmap.ic_launcher);
notificationBuilder.setContentIntent(pendingIntent);
NotificationManager notificationManager = (NotificationManager)getSystemService(Context.NOTIFICATION_SERVICE);
notificationManager.notify(0,notificationBuilder.build());
}
}
FirebaseInstanceIdService :
package com.example.firebasenf.firebasenf;
import android.util.Log;
import com.google.firebase.iid.FirebaseInstanceId;
import com.google.firebase.iid.FirebaseInstanceIdService;
public class MyFirebaseInstanceIDService extends FirebaseInstanceIdService {
private static final String REG_TOKEN = "REG_TOKEN";
#Override
public void onTokenRefresh(){
String recent_token = FirebaseInstanceId.getInstance().getToken();
Log.d(REG_TOKEN,recent_token);
}
}

you need to override onMessageReceived in MyFirebaseMessagingService class to do some actions when notification is pushed.
doc
By overriding the method FirebaseMessagingService.onMessageReceived,
you can perform actions based on the received RemoteMessage object and
get the message data
#Override
public void onMessageReceived(RemoteMessage remoteMessage)
{
Log.d(TAG, "From: " + "Notification Received");
// TODO(developer): Handle FCM messages here.
Log.d(TAG, "From: " + remoteMessage.getFrom());
// Check if message contains a data payload.
if (remoteMessage.getData().size() > 0)
{
Log.d(TAG, "Message data payload: " + remoteMessage.getData());
}
// Check if message contains a notification payload.
if (remoteMessage.getNotification() != null) {
Log.d(TAG, "Message Notification Body: " + remoteMessage.getNotification().getBody());
}
// Also if you intend on generating your own notifications as a result of a received FCM
// message, here is where that should be initiated. See sendNotification method below.
//You may want show notification
}
keep in mind onMessageReceived will only triggered if the app in foreground
When your app is in the background, Android directs notification
messages to the system tray. A user tap on the notification opens the
app launcher by default.

Sending Push Notification From QuickBlox in Android

I've used the quickblox chat sample and it worked fine, But I wanted to use push notifications in it.. So I followed some tutorials and read the sample and just done like it.. But when I push notification from QuickBlox Admin Panel: Messages no thing happens in my application.. No Logs, No Notifications.. No Thing..!
I'm sure that the project number and api key are correct..

}
And I get that registration done successfully.. :S
I've been searching for the solution for 2 days now :/ Any help will be appreciated.. Thanks.

I don't have enough reputation to comment, so I am putting this as a possible answer -
I have been working through the same for the last couple of days, and here are a couple of things to check:
When you set up the GCM API key, did you set any IPs? You should leave this blank to accept all.
When you say the registration is done successfully, do you mean you get the onSuccess Log message from subscribeToPushNotificationsTask? Check your device id; I was getting null for deviceId from:
String deviceId = ((TelephonyManager)getBaseContext().getSystemService(Context.TELEPHONY_SERVICE)).getDeviceId();
So instead I had to use
String deviceId = Secure.getString(this.getContentResolver(), Secure.ANDROID_ID);
What options were you selecting in the Quickblox Admin Panel > Messages? Be sure you are selecting "GCM (Android Push)" under the channel option.
Lastly, make sure you are using all production or all development for your environments (QBEnvironment.DEVELOPMENT). I somehow ended up with a mix, and switched them all to production now.
My push notifications are now working, so perhaps I can help out more if you have specific questions.

Will BroadcastReceiver expend battery?

I know the AlarmManagerBroadcastReceiver will stay system to keep watch over SMS after I installed the .apk
Will the AlarmManagerBroadcastReceiver expend battery even if I never receive s SMS?
Do I need disable the AlarmManagerBroadcastReceiver when I stop watch SMS ?

As discussed here, an incoming SMS belongs to a special group of low-level system events that will cause the CPU to wake from the battery-saving "sleep mode" (this group includes incoming calls, incoming mobile data packets and AlarmManager events). The device's GSM radio will listen to incoming SMS regardless of your broadcast receiver being set or not. When an SMS arrives, the system will choose which receiver(s) will handle it. Thus, having a SMS broadcast receiver registered has no impact in the battery consumption. Besides, energy consumption due to a registered receiver in memory is not significant.
You can unregister the broadcast receiver programmatically if there is a functional requirement to do so.

Because you have fined your AlarmManagerBroadcastReceiver in the android manifest, android will wake up your app and call the AlarmManagerBroadcastReceiver every time an sms is received.
If no SMS are received, your app won't be woken up so there won't be any impact on battery.
If you want control over when to receive those broadcasts, register and unregister your receiver programmatically through the registerReceiver(BroadcastReceiver receiver, IntentFilter filter) method on a Context (e.g. Activity).

Android AlarmManager Randomly Scheduling Notifications?

I'm trying to create a reminder application that pops up a reminder in the status bar. As I understand, the Android NotificationManager is the standard tool to use to schedule notifications however a BootService is needed in order to re-schedule notifications as scheduled events do not survive across boots.
I've pieced together an application below which schedules a single reminder at boot time, and pops up a notification in the status bar. If you click the notification, it launches MainActivity which, in the future, will have options to add more reminders, delete them, or whatever.
The problem I'm having is that the reminder works correctly the first time however it seems to be re-scheduling itself and popping up again at random times for some reason. Should I be launching another activity rather than the one which installs the BootAlarmService?
UPDATE:
So I think I found some clues with logcat. Apparently the Service is crashing and being restarted which is resetting the Notification. Any ideas why this is?
UPDATE II : code changed to working model

In case it helps someone else, I think I needed to check the passed Intent for NULL in the onStartCommand() method both in BootAlarmService.java as well as NotificationAlarmService.java. Only been testing it a couple days but it looks like the Intent is NULL if the system kills/restarts the service. Simply testing for this allowed me to create the notification only when the service is started at Boot-time (when the passed Intent is NOT null).
