Facebook統合アプリケーションを作成しました。問題なく正しくログインおよびログアウトでき、ログインしてアプリを閉じてから再度開くと、正しくログアウトできます。しかし、私の問題は、ログインしてEclipseからアプリケーションを実行すると、ログアウトできないことです。エラーが表示されます。

  @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
           facebook = new Facebook(APP_ID);
           mAsyncRunner = new AsyncFacebookRunner(facebook);

        sharePref = getPreferences(MODE_PRIVATE);
        facebook.setAccessToken(sharePref.getString(ACCESS_TOKEN, null));
        facebook.setAccessExpires(sharePref.getLong(EXPIRE_SESSION, 0));

    buttonLogin.setOnClickListener(new OnClickListener() {
            @Override
            public void onClick(View v) {
                loginToFacebook();
            }
        });

buttonLogout.setOnClickListener(new OnClickListener() {
            @Override
            public void onClick(View v) {
                logoutFacebook();
            }
        });
}

public void loginToFacebook() {


        if (!facebook.isSessionValid()) {
            facebook.authorize(this, PERMISSIONS, Facebook.FORCE_DIALOG_AUTH,
                    new DialogListener() {
                        @Override
                        public void onFacebookError(FacebookError e) {
                        }

                        @Override

                            SharedPreferences.Editor editor = sharePref.edit();
                            editor.putString(ACCESS_TOKEN,
                                    facebook.getAccessToken());
                            editor.putLong(EXPIRE_SESSION,
                                    facebook.getAccessExpires());
                            editor.commit();
                        }

                        @Override

                                Log.e("Logout from Facebook", "Great");
                            }
                        }

これを試して..

以下の行を mainactivity.. から削除します。

sharePref = getPreferences(MODE_PRIVATE);
        facebook.setAccessToken(sharePref.getString(ACCESS_TOKEN, null));
        facebook.setAccessExpires(sharePref.getLong(EXPIRE_SESSION, 0));

ログイン機能の内部に以下の行を追加します

  mPrefs = getPreferences(MODE_PRIVATE);
            String access_token = mPrefs.getString("access_token", null);
            long expires = mPrefs.getLong("access_expires", 0);

            if (access_token != null) {
                facebook.setAccessToken(access_token);
Toast.makeText(getApplicationContext(), "You Already Login",
                    Toast.LENGTH_SHORT).show();
            }

            if (expires != 0) {
                facebook.setAccessExpires(expires);
Toast.makeText(getApplicationContext(), "You Already Login",
                    Toast.LENGTH_SHORT).show();
            }
