  <blockquote>
    <p>GoogleService failed to initialize, status: 10, Missing an expected resource: 'R.string.google_app_id' for initializing Google services.  Possible causes are missing google-services.json or com.google.gms.google-services gradle plugin.</p>

  <p>when I run the same code with Dubug.APK it's working fine.</p>
  
  <p>below is build.gradle file</p>
