Could not get google_app_id in google services file from build environment

Explanation:

In Android development, the google_app_id refers to the unique identifier for your Firebase project. This error occurs when the Google Services plugin is unable to find the google_app_id value specified in your project’s Google Services file.

To resolve this issue, follow these steps:

1. Make sure you have properly set up Firebase in your project.
2. Check if you have the google-services.json file in your app module’s root directory. This file contains important configuration information, including the google_app_id value.
3. If you don’t have the google-services.json file, you need to download it from the Firebase console. Go to your project settings in the Firebase console and click on the “Download google-services.json” button. Place this file in your app module’s root directory.
4. Ensure that the google-services plugin is applied correctly in your app-level build.gradle file. It should be added as a dependency and should be placed as the last line in the file. For example:

// Example build.gradle file
  dependencies {
    // other dependencies
    implementation 'com.google.firebase:firebase-analytics:17.3.0'
    implementation 'com.google.firebase:firebase-auth:19.2.0'
    // other dependencies
  }
  
  apply plugin: 'com.android.application'
  apply plugin: 'com.google.gms.google-services'
  

After following these steps, clean and rebuild your project to ensure that all the dependencies are resolved properly. This should fix the error and enable you to retrieve the google_app_id from the Google Services file in the build environment.
