I'm trying to authenticate my users using firebase authentication, but this error pops up.
I've already added the SHA1, but it still doesn't work.
E/AuthUI: A sign-in error occurred. com.firebase.ui.auth.FirebaseUiException: Code: 16, message: 16: at com.firebase.ui.auth.data.remote.GoogleSignInHandler.onActivityResult(GoogleSignInHandler.java:110) at com.firebase.ui.auth.ui.idp.SingleSignInActivity.onActivityResult(SingleSignInActivity.java:128) at android.app.Activity.dispatchActivityResult(Activity.java:7454) at android.app.ActivityThread.deliverResults(ActivityThread.java:4353) at android.app.ActivityThread.handleSendResult(ActivityThread.java:4402) at android.app.servertransaction.ActivityResultItem.execute(ActivityResultItem.java:49) at android.app.servertransaction.TransactionExecutor.executeCallbacks(TransactionExecutor.java:108) at android.app.servertransaction.TransactionExecutor.execute(TransactionExecutor.java:68) at android.app.ActivityThread$H.handleMessage(ActivityThread.java:1808) at android.os.Handler.dispatchMessage(Handler.java:106) at android.os.Looper.loop(Looper.java:193) at android.app.ActivityThread.main(ActivityThread.java:6669) at java.lang.reflect.Method.invoke(Native Method) at com.android.internal.os.RuntimeInit$MethodAndArgsCaller.run(RuntimeInit.java:493) at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:858)
