In development mode my google signIn work fine but in Production mode I'm not able to SignIn from Google login So I found we have to create Release SHA1 key for Production but I'm Unable to Create It gives me error (noClassDefFoundError). Please help me where I'm Wrong.
Is the password for the .jks file you are trying to sign for correct?
Alternatively you could try generating a new .jks file like below:
In android studio. Build -> Generate Signed APK... and click Next and Generate New

Add your details here and Copy your key store path and key alias.
Traverse to the "bin" folder of the jdk path present in Java.
Open terminal and enter:
keytool -list -v -keystore "key store path" -alias "key alias"
Enter your key password and this will print out your release SHA1.
Check whether this works?
