FireBase stuck on "Run your app to verify installation" for android

Question

I'm new to android development, since a long time, I'm stuck in one error that is Run your app to verify installation (Checking if the app has communicated with our servers. You may need to uninstall and reinstall your app.)

build.gradle(Module:app)     dependencies {         implementation fileTree(dir: 'libs', include: ['*.jar'])         implementation 'com.android.support:appcompat-v7:26.1.0'         implementation 'com.android.support.constraint:constraint-layout:1.1.3'         testImplementation 'junit:junit:4.12'         androidTestImplementation 'com.android.support.test:runner:1.0.2'         androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.2'         implementation 'com.google.firebase:firebase-core:16.0.1'     }       dependencies {             classpath 'com.android.tools.build:gradle:3.3.2'             classpath 'com.google.gms:google-services:4.0.1'             // NOTE: Do not place your application dependencies here; they belong             // in the individual module build.gradle files         } 

Answer 1

You have to do nothing for your question but run the app on the android emulator or a real android device. If you have made your app and later added the dependencies, then you need to delete the app from the device/emulator and install the app again.

By doing this, when the app runs, it passes variables from the google-services.json file to the firebase servers and checks if the same app is communicating or not.

This step is to verify the correct installation of firebase dependencies in the app. If you find it difficult, you can skip the process anyway.
