Google sign-in fragment returning RESULT_CANCELED

Question

I am trying to integrate Google sign-in into my android app using Firebase, but I am running into issues. I am following the tutorial here, and I believe that I have followed it to the word. I added Firebase to my app, added my SHA-1 fingerprint, enabled Google sign-in, and added the dependencies to my grade files. Then, I copied the code in the github project linked to in the tutorial. However, when I run the application, and my code is below, I get an error when the sign-in fragment returns, and the result code is RESULT_CANCELED. This is the error output:

W/GoogleSignInActivity: Google sign in failed, resultCode: 0
                    com.google.android.gms.common.api.ApiException: 10:

                        at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:767)

When I created the SHA-1 fingerprint, I did have to remake the debug keystore at ~/.android/debug.keystore using the command

keytool -genkey -v -keystore ~/.android/debug.keystore -storepass android -alias androiddebugkey -keypass android -dname "CN=Android Debug,O=Android,C=US"

and then I converted the keystore to pkcs12 using the command

keytool -importkeystore -srckeystore ~/.android/debug.keystore -destkeystore ~/.android/debug.keystore -deststoretype pkcs12

I have never used Firebase or Google sign-in for authentication, so I am very lost. I think the keystore might be the problem, and when I look in File > Project Structure > Signings nothing is shown in the left panel, and in File > Project Structure > Build Types the Signing Config box is empty. Again, I am very new to Firebase and Google authentication, so please excuse me if I'm forgetting something simple. Thank you in advance for your help.

This is the code for my main activity. The layout is simply a Google sign-in button and the action bar.

com.google.android.gms.common.api.ApiException: 10 is explained by the following blockquote.

DEVELOPER ERROR The application is misconfigured. This error is not recoverable and will be treated as fatal. The developer should look at the logs after this to determine more actionable information.

This means that you could either have something wrong with your SHA-1 fingerprint or your OAuth 2.0 client ID. I doubt that there's anything wrong with your SHA-1 configuration since you followed the tutorial. The only thing left is to get your proper client ID. You first go to https://console.cloud.google.com/apis/credentials.

1. Look for anything related to Android and is under OAuth 2.0 client IDs.

2. Replace part of your codes with the following:

   GoogleSignInOptions gso = new GoogleSignInOptions.Builder(GoogleSignInOptions.DEFAULT_SIGN_IN)
           .requestIdToken(webClientId)
           .requestEmail()
           .build();
   

The variable webClientId holds the Client ID you previously got from https://console.cloud.google.com/apis/credentials. Then, there you go.

1. Create New Project using Firebase developer Account. And Put your google-services.json within Your ProjectName/App.
2. Then Go to the Firebase developer console --> Select your project --> Click Project Overview(Left Side)--> Select your project Settings.
3. Go to Your app section ---> update SHA certificate fingerprints How to get debuger SHA1 Key?
4. Go to the android studio --> Click Gradle on the right Pannel.
5. Click on your Project Name(root). ---> click Tasks -->signing Report
6. Click on Gradle Console in Buttom Panel.
7. Then you got your SHA1 key.

Next: 1. Go to the Firebase developer console and select your project. 2. Click Authetication in left side panel. 3. Click SIGN IN METHOD and enable Google As true.

Answer 3

Make sure you have the pre-requisites set up correctly :-

1. You have added your SHA-1 debug key to your Project's configuration setting on Google or Firebase Account.
2. Downloaded and added google-services.json to your android project after adding the debug SHA1 key in your account.
3. Package name (on Firebase account) and Application Id (on android) must be same .. Android's package name might be different, no problems with that.

After that, simply edit the existing debug signing config in your android project's setting as mentioned here https://stackoverflow.com/a/17992232/9747826

MAKE SURE YOU IMPLEMENT BOTH THE STEPS AS MENTIONED HERE

This will setup project's default signing configuration to debug with your debug-keystore SHA1 and you are good to go!

Answer 4

Another reason why RESULT_CANCELED might be returned is when the activity from which you launch the authentication has android:launchMode="singleTask" configured in AndroidManifest.xml, in which case it will always get RESULT_CANCELED on its onActivityResult() method.

Changing it to android:launchMode="singleTop" fixed the issue.
