I have added the Google Sign in in my application and made it work by following all the steps in the official documentation. Everything worked fine, until I generated a signed apk for publishing. The app could not sign in , the

Log.d(TAG, "handleSignInResult:" + result.isSuccess());

in SignInActivity.java's handleSignInResult() gives the value as false.

I have registered the app on the developer console and provided the SHA1 key for they debug key as well as the release key. I am unable to solve this and couldn't find anything related in the documentation either.

When you upload an apk to the play store then play store creates a new SHA1 key called "App signing certificate". You get that SHA1 and save in your console or firebase account (as you need).

New SHA1 will be found at Released Management->App Sigining on your play console.

or

when you build signed apk with your filename.jks it has different SHA than your debug apk, put these SHA which is generated by signed apk in Firebase nd update it and again download json from firebase and override existing json from your android studio.

Before publishing app you should read Google Play launch checklist
