title: Android :What is the difference between app signing certificate and upload certificate?
body: <p>What is the difference between app signing certificate and upload certificate?
  I am having trouble with integrating Google Play Games with my app (I posted about this as another question) and I noticed that the one that is used for client Id that is automatically generated on Google API Console is called signing certificate.<br>
  However, what I can see when I run signing in report on Android Studio is called upload certificate. </p>
  
  <p>Which one is supposed to set for client Id? By the way both didn't solve my problem but I am curious about the difference.</p>
