I'm new to android development. I've downloaded facebook sdk 3.0.1, and using the sample code to log in. The problem is, that if facebook app is installed the authentication fails. (otherwise it works just fine) after pressing the log in button I get to onActivityResult with status CLOSED_LOGIN_FAILED. of course I'm not typing the password, it's done automatically through facebook's app, and the facebook app is logged in and works properly. I couldn't find a solution.. please help me :)

this is my code:

@Override
protected void onCreate(Bundle savedInstanceState) {
    instance = this;
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    buttonLoginToFacebook = (Button) findViewById(R.id.buttonLoginToFacebook);
    tvWellcome = (TextView) findViewById(R.id.tvWellcome);

    Settings.addLoggingBehavior(LoggingBehavior.INCLUDE_ACCESS_TOKENS);

    Session session = Session.getActiveSession();
    if (session == null) {
        if (savedInstanceState != null) {
            session = Session.restoreSession(this, null, statusCallback,
                    savedInstanceState);
        }
        if (session == null) {
            session = new Session(this);
        }
        Session.setActiveSession(session);
        if (session.getState().equals(SessionState.CREATED_TOKEN_LOADED)) {
            session.openForRead(new Session.OpenRequest(this)
                    .setCallback(statusCallback));
        }
    }

    updateView();
}

@Override
public void onStart() {
    super.onStart();
    Session.getActiveSession().addCallback(statusCallback);
}

@Override
public void onStop() {
    super.onStop();
    Session.getActiveSession().removeCallback(statusCallback);
}

@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    Session.getActiveSession().onActivityResult(this, requestCode,
            resultCode, data);
    updateView();
}

@Override
protected void onSaveInstanceState(Bundle outState) {
    super.onSaveInstanceState(outState);
    Session session = Session.getActiveSession();
    Session.saveSession(session, outState);
}

private void updateView() {
    Session session = Session.getActiveSession();
    if (session.isOpened()) {
        Intent intent = new Intent(this, ScreenStartPage.class);
        startActivity(intent);
    } else {
        buttonLoginToFacebook.setOnClickListener(new OnClickListener() {
            public void onClick(View view) {
                onClickLogin();
            }
        });
    }
}

private void onClickLogin() {
    Session session = Session.getActiveSession();
    if (!session.isOpened() && !session.isClosed()) {
        session.openForRead(new Session.OpenRequest(this)
                .setCallback(statusCallback));
        updateView();
    } else {
        Session.openActiveSession(this, true, statusCallback);
    }
}


public void onClickLogout() {
    Session session = Session.getActiveSession();
    if (!session.isClosed()) {
        session.closeAndClearTokenInformation();
    }
}

private class SessionStatusCallback implements Session.StatusCallback {
    @Override
    public void call(Session session, SessionState state,
            Exception exception) {
        updateView();
    }
}

您是否在 Facebook 的应用设置仪表板中设置了调试密钥哈希和完整的类名？请参阅Android 版 Facebook SDK 入门文档中的步骤 5 和 6 。
