 You will also need to enable any OAuth APIs that you want, using the

 example, if you want to mimic the behavior of the Google Sign-In example app,

+### Troubleshooting
+
+If you encounter persistent errors, check that you have followed all of the
+registration steps in the instructions above. Common signs of configuration
+errors include:
+* `GoogleSignInException`s with a code of
+  `GoogleSignInExceptionCode.clientConfigurationError`.
+* Unexpected `GoogleSignInException`s with a code of
+  `GoogleSignInExceptionCode.canceled` after selecting an account during the
+  authentication process.
+  * Some configuration errors will cause the underlying
+    Android `CredentialManager` SDK to return a "canceled" error in this flow,
+    and unfortunately the `google_sign_in` plugin has no way to distinguish this
+    case from the user canceling sign-in, so cannot return a more accurate error
+    message.
+* Sign-in working in one build configuration but not another.
+
+Common sources of configuration errors include:
+* Missing or incorrect `serverClientId`.
+* Missing or incorrect signing SHA for one or more build configurations.
+* Incorrect Android package name on the server side.
