GoogleSIgnInClient автоматически регистрируется после выхода

Question

Ниже мой код, пожалуйста, помогите мне с ним. Всякий раз, когда я выхожу из приложения и пытаюсь войти снова, он входит в систему автоматически с помощью предыдущих учетных данных, но я хочу ограничить то же самое, я хочу, чтобы GoogleSignIn попросил меня входить в систему всякий раз, когда я нажимаю на него

Пожалуйста, помогите мне !!!! Я хочу выполнить вход из другой учетной записи, когда нажимаю кнопку GoogleSignIn. Заранее спасибо

Answer 1

Пожалуйста, попробуйте это:

 sign_out_app.setOnClickListener {
            signInClient.signOut()
            fAuth.signOut()//add this line     
            sign_out_app.visibility = View.GONE
            Toast.makeText(applicationContext, "Signed Out!!!", Toast.LENGTH_LONG).show()
 }

Это может быть полезно !!!

protected void onActivityResult(int requestCode, int resultCode, Intent data) {
            super.onActivityResult(requestCode, resultCode, data);
            if (requestCode == 2) {
                GoogleSignInResult result = Auth.GoogleSignInApi.getSignInResultFromIntent(data);
                if (result.isSuccess()) {
                    GoogleSignInAccount acct = result.getSignInAccount();
                    if(acct!=null) {            
                        //Take all data You Want
                        String identifier = acct.getId()+"";                 
                        String displayName = acct.getDisplayName()+"";
                        //After You got your data add this to clear the priviously selected mail
                        mGoogleApiClient.clearDefaultAccountAndReconnect();
                    }
                }else Log.e("handleSignInResult","Failed ; "+result.getStatus());
            }
