FirebaseInstanceIdService getToken returning null

Question

Im trying to add FCM notifications to my app, but for some reason

FirebaseInstanceId.getInstance().getToken();

is returning null.

Since im not getting any stacktrace my best guess is that FirebaseInstanceIdService is not working

Google Play Services version: 9.6.1
Firebase-messaging version : 9.6.1
added json config file from FirebaseConsole (Tried single file with 2 clients inside it, one for debug and one for release build) and 2 files each for respective build

Iw applied google services plugin at the bottom of my modules gradle script Included google services in projects root gradle script

Created 2 services from the officail docs:

public class MyFirebaseInsanceIDService  extends FirebaseInstanceIdService {

private static final String TAG = "MyFirebaseIIDService";

@Override
public void onTokenRefresh() {
    // Get updated InstanceID token.
    String refreshedToken = FirebaseInstanceId.getInstance().getToken();
    PreferencesHelper.putSharedPreferencesString(Constants.User.PUSH_NOTIFICATIONS, refreshedToken);

    Log.e("TOKEN", "Token: " + FirebaseInstanceId.getInstance().getToken());
}

}

And the manifest:

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
package="com.fc.test">

<uses-permission android:name="android.permission.DISABLE_KEYGUARD" />

        transitive = true;
    }
}
apply plugin: 'com.google.gms.google-services

Note that im using tools:node="replace" in my root application tag. Is it possible that FirebaseInstanceIdService is not added to the manifest since it has the same intent filter as mine FirebaseInstanceService and thus not being called?

So my question here would be is there something wrong it the official docs or in my implementation that should cause the Instance token to be null?

Is a current version of Google Play Services installed on your device or emulator? — Bob Snyder

Check that the Sender ID shown on the Cloud Messaging tab of the Project Settings at the Firebase Console matches the project_number included in your google-services.json file. — Bob Snyder

I starting to think you are right about tools:node="replace" being the problem, but don't know specifically why. Is it possible to build you app without it? — Bob Snyder

After digging up thru old implementations of FCM and generated manifests, I can now say that manifest merger is the problem.

Solution for this problem is adding these classes to the apps manifest manualy

 <activity
        android:name="com.google.android.gms.common.api.GoogleApiActivity"
        android:exported="false"
        android:theme="@android:style/Theme.Translucent.NoTitleBar" />

    <meta-data
        android:name="com.google.android.gms.version"
        android:value="@integer/google_play_services_version" />

    <service
        android:name="com.google.firebase.messaging.FirebaseMessagingService"
        android:exported="true" >
        <intent-filter android:priority="-500" >
            <action android:name="com.google.firebase.MESSAGING_EVENT" />
        </intent-filter>
    </service>

    <receiver
        android:name="com.google.firebase.iid.FirebaseInstanceIdReceiver"
        android:exported="true"
        android:permission="com.google.android.c2dm.permission.SEND" >
        <intent-filter>
            <action android:name="com.google.android.c2dm.intent.RECEIVE" />
            <action android:name="com.google.android.c2dm.intent.REGISTRATION" />

            <category android:name="com.fc.debug" />
        </intent-filter>
    </receiver>


    <receiver
        android:name="com.google.firebase.iid.FirebaseInstanceIdInternalReceiver"
        android:exported="false" />
    <!--

    -->
    <service
        android:name="com.google.firebase.iid.FirebaseInstanceIdService"
        android:exported="true" >
        <intent-filter android:priority="-500" >
            <action android:name="com.google.firebase.INSTANCE_ID_EVENT" />
        </intent-filter>
    </service>

    <provider
        android:name="com.google.firebase.provider.FirebaseInitProvider"
        android:authorities="com.fc.debug.firebaseinitprovider"
        android:exported="false"
        android:initOrder="100" />

    <receiver
        android:name="com.google.android.gms.measurement.AppMeasurementReceiver"
        android:enabled="true" >
        <intent-filter>
            <action android:name="com.google.android.gms.measurement.UPLOAD" />
        </intent-filter>
    </receiver>

    <service
        android:name="com.google.android.gms.measurement.AppMeasurementService"
        android:enabled="true"
        android:exported="false" />

While I was doing the migration I had a problem, it was that I didn't receive any Notification. To solve this and If you have your GCM working, don't forget to include your sender ID when you get the Firebase Token. To consult this ID you have to navigate to your Firebase project and click Project Name. Click the Setting icon and select "Project Setting" menu Select "Could Messaging" tab and use sender ID on the page.

And when says to code this:

     token = FirebaseInstanceId.getInstance().getToken();

You have to use this:

     token = FirebaseInstanceId.getInstance().getToken("YOUR_SENDER_ID", "FCM");

It works for me, I hope this helps you ;)

This worked for me:

String token = FirebaseInstanceId.getInstance().getInstanceId().getResult().getToken();

First genarate "google-services.json" and Add this file in your android studio Like this projectFolder/APP/google-services.json

Add classpath to top level build.gradle

 dependencies {
        classpath 'com.android.tools.build:gradle:2.1.2'
        classpath 'com.google.gms:google-services:3.0.0'
        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }

Add following plugin and dependencies in app’s build.gradle

apply plugin: 'com.google.gms.google-services'
dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    testCompile 'junit:junit:4.12'
    compile 'com.android.support:appcompat-v7:24.0.0'
    compile 'com.google.firebase:firebase-core:9.4.0'
    compile 'com.google.firebase:firebase-messaging:9.4.0'
}

Add following Firebase services in your java files

FirebaseIDService.java

package com.galleonsoft.firebase.push;

import android.util.Log;

import com.google.firebase.iid.FirebaseInstanceId;
import com.google.firebase.iid.FirebaseInstanceIdService;

public class FirebaseIDService extends FirebaseInstanceIdService {
    private static final String TAG = "FirebaseIDService";

    @Override
    public void onTokenRefresh() {
        // Get updated InstanceID token.
        String refreshedToken = FirebaseInstanceId.getInstance().getToken();
        Log.d(TAG, "Refreshed token: " + refreshedToken);

        // TODO: Implement this method to send any registration to your app's servers.
        sendRegistrationToServer(refreshedToken);
    }

    private void sendRegistrationToServer(String token) {
        // Add custom implementation, as needed.
    }
}

MyFirebaseMessagingService.java

package com.galleonsoft.firebase.push;

import android.util.Log;

import com.google.firebase.messaging.FirebaseMessagingService;
import com.google.firebase.messaging.RemoteMessage;

public class MyFirebaseMEssagingService extends FirebaseMessagingService {
    private static final String TAG = "FCM Service";
    @Override
    public void onMessageReceived(RemoteMessage remoteMessage) {
        // TODO: Handle FCM messages here.
        // If the application is in the foreground handle both data and notification messages here.
        // Also if you intend on generating your own notifications as a result of a received FCM
        // message, here is where that should be initiated.
        Log.d(TAG, "From: " + remoteMessage.getFrom());
        Log.d(TAG, "Notification Message Body: " + remoteMessage.getNotification().getBody());
    }
}

Add service in your AndroidMainifest.xml file

<service android:name=".MyFirebaseMEssagingService">
    <intent-filter>
        <action android:name="com.google.firebase.MESSAGING_EVENT"/>
    </intent-filter>
</service>

<service android:name=".FirebaseIDService">
    <intent-filter>
        <action android:name="com.google.firebase.INSTANCE_ID_EVENT"/>
    </intent-filter>
</service>

Iw done all of this, and btw you have an error in your example 'apply plugin: 'com.google.gms.google-services'' should go on the bottom of the apps module

Jigar Patel Over a year ago

Remember internet permission in mainifest files <uses-permission android:name="android.permission.INTERNET" />

Ivan Milisavljevic Over a year ago

Thank you :) but I have that as well

Jigar Patel Over a year ago

add gradle code in both files. And Get google-services.json files from firebase and put in app folder.
