FirebaseInstanceIdService getToken returning null

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

<application

    android:theme="@style/AppTheme"
    tools:node="replace">

        </intent-filter>
    </service>

    <service
        android:name="com.fc.test.MyFirebaseMessagingService"
        android:enabled="true"
        android:exported="true">

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

    <activity
        android:name="com.fc.test.view.splash.Splash"
        android:screenOrientation="portrait"
        android:theme="@style/AppTheme.CenterAnimation">

        </intent-filter>
    </activity>

</application>

root Gradle:

buildscript {
    repositories {
        jcenter()
        maven { url 'https://maven.fabric.io/public' }
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:2.1.2'

    compileSdkVersion = 24
    minSdkVersion = 15
    targetSdkVersion = 24
    supportLibraryVersion = '24.2.1'
}

and the main part of the modules Gradle

    def jUnit = "junit:junit:4.12"
    def mockito = "org.mockito:mockito-core:1.10.19"
    // App Dependencies
    compile "com.google.android.gms:play-services-gcm:$PLAY_SERVICES_VERSION"

    compile "com.squareup.retrofit2:adapter-rxjava:$RETROFIT_VERSION"
    compile "com.jakewharton:butterknife:$BUTTERKNIFE_VERSION"
    compile('com.crashlytics.sdk.android:crashlytics:2.6.5@aar') {
        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?

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" />
