Migrating from GCM to Firebase

Since the AppMetrica Push SDK version 0.2.0, it uses the Firebase Cloud Messaging (FCM) service to send push messages on the Android platform.

This section explains the steps for migrating the application from Google Cloud Messaging to Firebase Cloud Messaging.

Step 1. Import a project

Import a Google project (if you used Google APIs to create a project):

  1. Go to the Firebase console.
  2. Click the Add project button.
  3. In the drop-down list, select the name of the project you are planning to run push campaigns for.
  4. Select the country your organization is officially registered in and click Add Firebase.
  5. Click Add Firebase to your Android app and follow the instructions.

Step 2. Configuring your app

Edit the AndroidManifest.xml file:

  1. Rename ymp_gcm_project_number to ymp_gcm_default_sender_id and get the following result:

    <meta-data android:name="ymp_gcm_default_sender_id" android:value="number:SENDER_ID"/>
    Copied to clipboard

    SENDER_ID — The unique ID of the sender in Firebase. You can find it in the Firebase console: go to Project settings → Cloud Messaging and copy the value of the Sender ID field.

  2. Add the following to the application element:

    <meta-data android:name="ymp_firebase_default_app_id" android:value="APP_ID"/>
    Copied to clipboard

    APP_ID — ID of the app in Firebase. You can find it in the Firebase console: go to the Project settings. In the Your application section copy the value of the application ID field.
