What steps to take to verify my Android Firebase app is on the cloud

Question

I'm a newbie to the firebase cloud process. I have a commercial a security camera to view my house that I can view on my phone many miles from my home. Getting into IoT, I developed an Android app to turn a porch light on or off. My Android app works with my local internet but now I want to put it into the cloud so I can use it outside of my house internet. To check and see if the app is on the Firebase cloud? I use my security camera several miles away checking to see if OnOff app working on the cloud. As of now it is not working. What am doing wrong? I installed all the required code to for firebase. Sync works with id 'com.google.gms.google-services' and installed it on my phone. Here is my code. build.gradle(app) code

    plugins {
    id 'com.android.application'
    id 'com.google.gms.google-services'
