title: Google Signin:Error signing in the specified account. Please choose a different account
body: <p>This question already asked but I did not find any satisfactory answer.</p>
  
  <p>I followed each and every step of <a href="https://developers.google.com/+/mobile/android/samples/quickstart-android#credentials-screenshot" rel="nofollow">https://developers.google.com/+/mobile/android/samples/quickstart-android#credentials-screenshot</a> but instead of their package name I am using mine.</p>
  
  <p>There are two cases one is direct testing and one after signin the apk with keystore.</p>
  
  <p>When I am <strong>testing</strong> my app in that case signin with any google account working fine but after I generate my <code>signed apk</code> it is giving me <code>Error signing in the specified account. Please choose a different account</code>.</p>
  
  <p>If everything is same then why it is not working with <code>signed apk</code>?</p>
