Question

我正在开发一个与facebook集成的Android应用程序（我非常新）。我可以成功实现登录/注销部分。现在我需要我的Android应用程序在特定页面上发布（文本）。我不知道如何处理这个问题。我试着阅读所有类似的帖子。我使用＆＃34; facebook.request（page_id + / feed，参数，＆＃34; POST＆＃34;）＆＃34; ，这总是返回一个空指针异常，因为不推荐request(feed,parameters,"POST")方法（下面写的代码）。我试图按照facebook sdk教程，其中涉及access_tokens和graph apis，这让我更加困惑。我甚至不知道如何处理这个问题。如果有人可以指导我，那么对我来说这将是一件非常有帮助的事情。谢谢。

try{
  Tring response = facebook.request("me");
  Bundle parameters = new Bundle();
    parameters.putString("message", msg);
    parameters.putString("description", "test test test");
    // parameters.putByteArray("message", msg);
    response = facebook.request("me/feed", parameters, "POST");
    Log.d("Tests", "got response: " + response);
    if (response == null || response.equals("")
            || response.equals("false")) {
        Log.v("Error", "Blank response");
     }else{


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

}

}
