title: google signIn not working in release mode apk android
body: <p>In release mode, my google sign-in is not working, but it works fine in debug mode. I got a similar question from SO <a href="https://stackoverflow.com/questions/35561657/sign-in-with-google-for-android-not-working-in-release-apk">here</a>, but I didn't get perfect solutions.</p>
  <p>My <code>handleSignInResult</code> is coming <code>false</code> - How can this be fixed?</p>
