I am not getting FCM message probably FirebaseMessagingService is not running

I am using FCM for notification. Due to some issue, i am not getting notification when i am sending using FCM Cloud console.

<service android:name=".MyInstanceIDService"
android:exported="true">
<intent-filter>
<action android:name="com.google.firebase.MESSAGING_EVENT" />
</intent-filter>
</service>
<service android:name=".MyMessagingService">
<intent-filter>
<action android:name="com.google.firebase.INSTANCE_ID_EVENT" />
</intent-filter>
</service>


This is my both classes.

public class MyInstanceIDService extends FirebaseInstanceIdService {

private static final String TAG = "MyInstanceIDService";

@Override
public void onTokenRefresh() {
String refreshedToken = FirebaseInstanceId.getInstance().getToken();
System.out.println("Refreshed token: " + refreshedToken);
// Util.getInstance().saveDeviceID(UniversalImageLoaderConfigurationApplication.getContext(), refreshedToken);
// sendRegistrationToServer(refreshedToken);
}

}

public class MyMessagingService extends FirebaseMessagingService {

private static final String TAG = "MyMessagingService";

@Override
public void onMessageReceived(RemoteMessage remoteMessage) {
//Displaying data in log
//It is optional
// if(LOG)
Log.d(TAG, "From: " + remoteMessage.getFrom());
// Log.d(TAG, "Notification Message Body: " + remoteMessage.getNotification().getBody());

Map<String, String> data = remoteMessage.getData();
int id = Integer.parseInt(data.get("id"));
if (id == (Constants.NOTI_NOTIFCATION)) {
String title = data.get("title");
String body = data.get("body");
sendNotification(id, title, body, "");
} else {
sendNotification(1, "", "", "");
}

}

}


I noted that public void onTokenRefresh() never called. So i used it

String refreshedToken = FirebaseInstanceId.getInstance().getToken();

in my MainActivity and i am getting tokenID. probably FirebaseInstanceIdService and FirebaseMessagingService is not running. below is my gradle

implementation 'com.google.firebase:firebase-messaging:17.0.0'
implementation 'com.google.firebase:firebase-core:16.0.1'


and i also used

apply plugin: 'com.google.gms.google-services'


this is my root level gradle

buildscript {
repositories {
// google()
maven { url "https://maven.google.com" }
jcenter()
// mavenCentral()
google()
}
dependencies {
classpath 'com.android.tools.build:gradle:3.1.3'
classpath 'com.google.gms:google-services:4.0.1' // google-services plugin

}

}

allprojects {
repositories {
// google()
mavenLocal()
maven { url "https://maven.google.com" }
jcenter()
mavenCentral()
google()
}
}


onTokenRefresh() is called only once when the app is installed first time or when reinstalled. Uninstall the app and put a log in onTokenRefresh() and install it again and check in the logcat.

The actions are reversed for your service declarations. Change to this:

<service android:name=".MyInstanceIDService"
android:exported="true">
<intent-filter>
<action android:name="com.google.firebase.INSTANCE_ID_EVENT" />
</intent-filter>
</service>
<service android:name=".MyMessagingService">
<intent-filter>
<action android:name="com.google.firebase.MESSAGING_EVENT" />
</intent-filter>
</service>


See the example in the documentation.
