質問：
問題は、これが goDaddy がホストするオンライン データベースに投稿されないことです。だから私の質問はなぜですか、そしてそれを投稿するように修正するにはどうすればよいですか?
問題: PHP ページは、渡された名前と値のペアを受け取りません。

HttpURLConnection を使用するように提案されたコードを修正しました... fbid を取得しないという問題に絞り込みました。
お分かりのように、私はここで多くの宿題をしました... これが、postthread クラスに設定されている内容のログキャットです。投稿を行う私のクラスは次のとおりです。
07-02 16:41:45.108: I/PROJECTCARUSO(12308): response: {"posts":[null]}

public HttpPostThread(URL sERVICE_URL, ArrayList<NameValuePair> pairs, final Handler handler)
{
Log.i("PROJECTCARUSO", "Posting to URL: " + sERVICE_URL);
this.url =sERVICE_URL;
this.pairs = pairs;
if(pairs==null){
Log.i("PROJECTCARUSO", "URL parms were null");
this.pairs = new ArrayList<NameValuePair>();
}
}
@Override
public void run()
{
try {

String param="";

//you need to encode ONLY the values of the parameters
if (param == "") {
param=nvp.getName() + "=" + URLEncoder.encode(nvp.getValue(),"UTF-8");

}
}
Log.i("PROJECTCARUSO", "param: " + param.toString());
// Create connection
conn=(HttpURLConnection)url.openConnection();
//set the output to true, indicating you are outputting(uploading) POST data
conn.setDoOutput(true);
//once you set the output to true, you don't really need to set the request method to post, but I'm doing it anyway
conn.setRequestMethod("POST");
//Android documentation suggested that you set the length of the data you are sending to the server, BUT
// do NOT specify this length in the header by using conn.setRequestProperty("Content-Length", length);
//use this instead.

これがphpです：

} else {

私もJavaを試しました：

try {
HttpURLConnection conn = (HttpURLConnection) url.openConnection();
conn.setReadTimeout(10000);
conn.setConnectTimeout(15000);
conn.setRequestMethod("POST");
conn.setDoInput(true);
conn.setDoOutput(true);
List<NameValuePair> params = new ArrayList<NameValuePair>();
for (NameValuePair nvp : pairs) {
//you need to encode ONLY the values of the parameters
params.add(new BasicNameValuePair(nvp.getName(), nvp.getValue()));
Log.i("PROJECTCARUSO", "NVP: " + nvp.getName() + " - " + nvp.getValue());
}
OutputStream os = conn.getOutputStream();
BufferedWriter writer = new BufferedWriter(
new OutputStreamWriter(os, "UTF-8"));
writer.write(getQuery(params));
writer.close();
os.close();
conn.connect();
//build the string to store the response text from the server
String response= "";
//start listening to the stream
Scanner inStream = new Scanner(conn.getInputStream());
//process the stream and store it in StringBuilder
while(inStream.hasNextLine())
response+=(inStream.nextLine());
Log.i("PROJECTCARUSO","response: " + response);
} catch (ProtocolException e) {
