google-signin: Getting Developer Error even after putting everything in place in release mode (Android)

Maybe you turned on Google Play Signature in Play Market. This feature replaces your certificate by auto-generated by Google. You can find it at the Play Console on the page ‘App signature’. You can download deployment certificate or just copy-paste fingerprints MD5, SHA1, etc. Copy SHA1 to Firebase Console App settings Android app.

PS. Also, it works for Facebook sign in. Download the certificate and do something like this:

cat ~/Downloads/deployment_cert.der | openssl sha1 -binary | openssl base64

to get hash to use with Facebook application settings

PS. I’m not a contributor. I’m also dev. 😃

I use this package every year and every year I have to come back here. Lol

If you’re still having this problem try this solution https://github.com/react-native-community/google-signin/issues/706#issuecomment-656126219

I’m having same problem.

I’m having the same problem

If you are using firebase & still looking for solutions:

1. Please match your key fingerprint in firebase console.

2. Do not initialize the configuration with keys, I repeat, do not provide any configuration object in the .configure() function Do this GoogleSignIn.configure().

3. Point 2 will resolve the issue. 😃

Is there currently any solution to this problem? As many of you, I am struggling with the same problem. Everything is in place but I still get DEVELOPER_ERROR.

I am facing same developer_error since I am using android React native app to complete google singin. Also, I am not using Firebase to login I created both OauthCilent android and Web client 2 and giving same id here to signin

GoogleSignin.configure ({
      webClientId: '***.apps.googleusercontent.com',
})

also to create SHA-1 for android used this command to C:\Users\satailor\Documents\ReactNative_workspace\App>keytool -list -v -alias androiddebugkey -keystore C:\Users\satailor\Documents\ReactNative_workspace\app\android\app\debug.keystore and copied SHA-1 and added in google cloud console for same.

Inside Android folder following changes are added: settings.gradle file include ':react-native-google-signin', ':app'

android/build.gradle file included following lines:

buildscript {
 ext {
     googlePlayServicesAuthVersion = "17.0.0"
}

dependencies { 
classpath 'com.google.gms:google-services:4.3.2'} 

Help me to resolve an issue. Let me know any other information required.

Can’t seem to solve this issue. I have two custom keystores setup. What I did:

1. Exported the SHA-1 with keytool -exportcert -alias KEYSTORE_ALIAS -keystore KEYSTORE_PATH and inserted this to my dev and prod app in Firebase
2. Also on https://console.developers.google.com/ I have two OAuth 2.0-client-ID’s with the correct package names and SHA-1 fingerprints
3. Copied the webClientId from Firebase Console > Authentication > GoogleSignIn and added it before the signin with Google.Configure
4. My Android build buildTypes are as following:

    buildTypes {
        debug {
            debuggable true
            productFlavors.dev.signingConfig signingConfigs.dev
            productFlavors.prod.signingConfig signingConfigs.prod
        }
        release {
            debuggable false
            minifyEnabled enableProguardInReleaseBuilds
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
            proguardFiles fileTree(dir: "${project.rootDir}/proguard_libs", include: ["*.pro"]).asList().toArray()
            productFlavors.dev.signingConfig signingConfigs.dev
            productFlavors.prod.signingConfig signingConfigs.prod
        }
    }

1. Downloaded my latest google-services.json
2. Ran ./gradlew clean and adb uninstall com.packagename
3. npm run android

Still the same DEVELOPER_ERROR. I’m really out of options… Anyone suggestions?

Following this tutorial fixed the problem for me.
