카카오 톡 로그인을 했는데. 로그아웃은 어떻게하나요?

로그아웃

private void onClickLogout() {
UserManagement.requestLogout(new LogoutResponseCallback() {
    @Override
    public void onCompleteLogout() {
        redirectLoginActivity();
    }
});

}

앱연결해제

private void onClickUnlink() {
final String appendMessage = getString(R.string.com_kakao_confirm_unlink);
    new AlertDialog.Builder(this)
        .setMessage(appendMessage)
        .setPositiveButton(getString(R.string.com_kakao_ok_button),
            new DialogInterface.OnClickListener() {
                @Override
                public void onClick(DialogInterface dialog, int which) {
                    UserManagement.requestUnlink(new UnLinkResponseCallback() {
                        @Override
                        public void onFailure(ErrorResult errorResult) {
                            Logger.e(errorResult.toString());
                        }

                        @Override
                        public void onSessionClosed(ErrorResult errorResult) {
                            redirectLoginActivity();
                        }

                        @Override
                        public void onNotSignedUp() {
                            redirectSignupActivity();
                        }

                        @Override
                        public void onSuccess(Long userId) {
                            redirectLoginActivity();
                        }
                    });
                    dialog.dismiss();
                }
            })
        .setNegativeButton(getString(R.string.com_kakao_cancel_button),
            new DialogInterface.OnClickListener() {
                @Override
                public void onClick(DialogInterface dialog, int which) {
                    dialog.dismiss();
                }
            }).show();

}

가이드 사용자관리에 보시면 있어용ㅎㅎ
redirectLoginActivity(); 는 로그아웃하고 나타낼액티비티에요 ㅎㅎ
