facebook墙上的java帖子总是显示登录页面。。问题机器人

Question

我正在使用youtube上的graph api，我遇到了一些麻烦

我可以把味精发到墙上，效果很好。问题是，每次都会显示登录页面，用户必须单击ok按钮才能发送。我想在不显示页面的情况下发送，它应该只在第一次显示。我使用 共享偏好，但如果我不把这种方法称为facebook。autorize显示登录页面，在尝试发送视频之前，它不起作用

我做错了吗？谢谢你的帮助

我的代码：

protected void onCreate(Bundle savedInstanceState) {

    super.onCreate(savedInstanceState);
    setContentView(R.layout.facebook_lay);

    init();

    acessToken = loadAccessToken();
    Log.i("teste","Acesstoken depois do load : " + acessToken);

    if(acessToken == null || acessToken.equals("")){
        login();
    }else{
        Log.i("teste","Session valid com token salva ? " + mFacebook.isSessionValid());
        sendVideo();
    }


}

private void init(){
    mFacebook = new Facebook(APP_ID);
    videoUrl = getIntent().getExtras().getString("videoUrl");
    preferences = this.getSharedPreferences(APPLICATION_PREFERENCES,
            Context.MODE_PRIVATE);
}

private void login(){
    mFacebook.authorize(this, new String[] {"publish_stream","offline_access"},new AuthorizeListener());

}

public void postOnWall(String msg) {
  Log.i("teste", "Testing graph API wall post");
   try {
          Bundle parameters = new Bundle();
          parameters.putString("message", AUTO_MSG);
          parameters.putString("link", msg);
          mFacebook.request("me/feed", parameters, 
          "POST");

   } catch(Exception e) {
       e.printStackTrace();
   }
}

private void storeToken(String token){
    Log.i("teste","storeToken: " + token);
    Editor editor = preferences.edit();
    editor.putString(ACESS_TOKEN, token);
    editor.commit();
}

private String loadAccessToken() {
    String token = preferences.getString(ACESS_TOKEN, null);
    if (token != null && !token.equals("")  ) {
        return token;
    } else {
        return null;
    }
}

private void sendVideo(){
    dialog = ProgressDialog.show(FacebookView.this, "Sending","Enviando video ...");
    new Thread(){
        public void run() {
            postOnWall(videoUrl);
            dialog.dismiss();
            finish();
        };
    }.start();
}

class AuthorizeListener implements DialogListener{

    @Override
    public void onCancel() {
        Log.i("teste","Logou candelado!");
        finish();
    }

    @Override
    public void onComplete(Bundle values) {
        Log.i("teste","Logou com sucesso!");
        Log.i("teste", "AcessToken : " + mFacebook.getAccessToken());
        Log.i("teste", "AcessToken expires : " + mFacebook.getAccessExpires());
        Log.i("teste", "Session valid : " + mFacebook.isSessionValid());

        storeToken(mFacebook.getAccessToken());
        sendVideo();
    }

    @Override
    public void onError(DialogError e) {
        Log.i("teste","Erro ao logar: " + e.getMessage());
        finish();
    }

    @Override
    public void onFacebookError(FacebookError e) {
        Log.i("teste","FacebookError ao logar: " + e.getMessage());
        Log.i("teste","FacebookError ao logar Causa: " + e.getCause());
        e.printStackTrace();            
        finish();
    }

}

@Override

已经找到了答案。只需在facebook对象上设置令牌

acessToken=loadAccessToken（）； 日志i（“teste”，“Acesstoken deposis do load:”+Acesstoken）

if(acessToken == null || acessToken.equals("")){
    login();
}else{
   mFacebook.setAccessToken(acessToken); 
   Log.i("teste","Session valid com token salva ? " + mFacebook.isSessionValid());
   sendVideo();
}
