Firebase into framework7 integration

I’m trying to integrate Firebase into Framework7
In the creation of the proyect into Firebase console it said i must add some code in 2 build.gradle files; i’ve find some build.gradle files in my project, not only 2… so i don’t know where files are the ones to add these code-lines:

I’ve these folder and files:

C:\myAPP\cordova\platforms\android\build.gradle
C:\myAPP\cordova\platforms\android\app\build.gradle
C:\myAPP\cordova\platforms\android\CordovaLib\build.gradle

C:\myAPP\cordova\node_modules\cordova-android\bin\templates\project\build.gradle
C:\myAPP\cordova\node_modules\cordova-android\bin\templates\project\app\build.gradle

C:\myAPP\cordova\node_modules\cordova-android\framework\build.gradle

C:\myAPP\cordova\node_modules\cordova-android\bin\templates\cordova\lib\plugin-build.gradle
C:\myAPP\cordova\platforms\android\cordova\lib\plugin-build.gradle

In the firebase proyect configuration it said i must add these lines:

/*
Code to add in build.gradle proyect level (<proyect>/build.gradle):
*/

buildscript {
  repositories {
    // Check that you have the following line (if not, add it):
    google()  // Google's Maven repository
  }
  dependencies {
    ...
    // Add this line
    classpath 'com.google.gms:google-services:4.3.4'
  }
}

allprojects {
  ...
  repositories {
    // Check that you have the following line (if not, add it):
    google()  // Google's Maven repository
    ...
  }
}



/*
Code to add in build.gradle app level (<proyect>/<app-module>/build.gradle):
*/

apply plugin: 'com.android.application'
// Add this line
apply plugin: 'com.google.gms.google-services'

dependencies {
  // Import the Firebase BoM
  implementation platform('com.google.firebase:firebase-bom:26.2.0')

  // Add the dependencies for the desired Firebase products
  // https://firebase.google.com/docs/android/setup#available-libraries
}

I’ve added the google-services.json inside myAPP folder as said by firebase console

I’ve navigate throw the forum post without finding the answer… i’ve try the npm install --save firebase command but it send me errors

Thanks in advance…
