Inside the project, select "Add Firebase to your Android app" (make sure to enter the right package name of your app).
google-services.json file to your computer and
copy it in your project
3. In your project
android/app/build.gradle make sure that your
compileSdkVersion is at least 26 and to add the following at the end of the file:
apply plugin: 'com.google.gms.google-services' // Include at the BOTTOM of file
4. Copy your project FCM Cloud Messaging Server Key from Google Firebase Console
(See the screenshot below and make sure to use the right api key)
5. Open NearIT web interface, select your app and navigate to “Settings > Push Settings”.
Paste your project FCM Key under the “Setup Android push notifications” block.
WARNING: Do not follow any further FCM-specific instructions: we automatically handle all the other part of the process inside the SDK code.
