Feature Tutorial

Using the Firebase Remote Config in Construct 3 is straightforward using this addon.

The only requirements are a Firebase account with an Android application, parameters declared in the Firebase Remote Config console, which will be retrieved by your Android application. And finally, matching the app id.

Kindly follow the steps below for the feature integration process walkthrough.


The first step is making a Firebase account, with an Android application.

Then, include the values you want your Construct 3 application to fetch, activate and retrieve.

Step 2 - Application ID

The second step is to match the application id of your Construct 3 mobile android application with the one in the Firebase Console.
This is the basis for the synchronization.
