title: how to find in ionic project (<android>/<app>/build.gradle)
body: <p>I'm trying to add Firebase to my android app builded with ionic, the firebase's documentation <a href="https://firebase.google.com/docs/android/setup" rel="nofollow noreferrer">https://firebase.google.com/docs/android/setup</a> says to add this line on my root-level build.gradle.</p>
  
  <p>Here's my Project-level build.gradle (/build.gradle):</p>
  
  <pre><code>buildscript {
    dependencies {
      // Add this line
      classpath 'com.google.gms:google-services:4.0.1'
   }
  }
  </code></pre>
  
  <p>App-level build.gradle (//build.gradle):</p>
  
  <pre><code>dependencies {
    // Add this line
    implementation 'com.google.firebase:firebase-core:16.0.1'
  }
  ...
  // Add to the bottom of the file
  apply plugin: 'com.google.gms.google-services'
  </code></pre>
