Migrating to FCM and Teak 2.0

GCM was deprecated April 10, 2018, and will be removed “as soon as April 11, 2019” according to Google.


The Teak SDK no longer supports GCM, but we’re going to make your migration to FCM as painless as possible.

Don’t Panic

  • It’s going to be ok
  • All of the push tokens Teak has collected will keep working
  • You don’t have to let Google collect analytics
  • You can always ask us for help

Import your GCM project as a Firebase project

Follow Google’s instructions to import your project to Firebase.


You only need to perform the Import your GCM project as a Firebase project step of those instructions.

This doc describes everything else you need to do.

Your live game will continue to work after this step, this step just adds Firebase, so there will not be a disruption in service.

Simplify your AndroidManifest.xml

Deleted code is debugged code, and we get to delete code!

Remove these permissions from your AndroidManifest.xml:

<permission android:name="<your-package-name>.permission.C2D_MESSAGE"
            android:protectionLevel="signature" />
<uses-permission android:name="<your-package-name>.permission.C2D_MESSAGE" />

Remove the Teak receiver from your AndroidManifest.xml:

<receiver android:name="io.teak.sdk.Teak" android:exported="false">
        <action android:name="YOUR_ANDROID_BUNDLE_ID.intent.TEAK_NOTIFICATION_OPENED" />
        <action android:name="YOUR_ANDROID_BUNDLE_ID.intent.TEAK_NOTIFICATION_CLEARED" />
        <category android:name="YOUR_ANDROID_BUNDLE_ID" />

Remove the Teak GCM Instance ID Listener Service from your AndroidManifest.xml:

<service android:name="io.teak.sdk.InstanceIDListenerService" android:exported="false" >
        <action android:name="com.google.android.gms.iid.InstanceID" />


Add the FCM dependency, remove the GCM dependency

If you use the Play Services Resolver plugin for Unity, these dependencies should be taken care of automatically.

We tested using version 1.2.95 of the Play Services Resolver plugin.


If you use other SDKs (Upsight, Leanplum, et. al.) they could be relying on GCM. You will need to make sure they support FCM, or remove them, since GCM and FCM can not live side-by-side.

If you do not currently use the Play Services Resolver plugin, we strongly suggest that you start. It turns your Android dependancies from AARs and JARs that have been copy-pasted into your repository into code.

If you really cannot use the Play Services Resolver plugin, make sure your dependencies are updated to Dependencies.


You must use Firebase’s Unity SDK, which uses google-services.json and an accompanying Gradle plugin to configure your Firebase App.

Optionally Disable Google’s Automatic Analytics Collection

Don’t want to send your purchase and session data to Google? You don’t have to!

Add this line to your AndroidManifest.xml:

<meta-data android:name="firebase_analytics_collection_deactivated" android:value="true" />
