XML-RPC錯誤，org.xmlpull.v1.XmlPullParserException

Question

我試着在Android中創建一個應用程序chatbot。我使用Pandorabots作爲Chatbot服務器。 Device Android與服務器之間的連接。我使用pandorabot XML-RPC API，並使用android-xmlrpc中的xml-rpc庫。所以這個我的代碼：

public class MainActivity extends Activity { 
private EditText editOne; 
private TextView textOne; 
private Button ButtonOne; 
private XMLRPCClient server; 
private URI uri; 

@Override 
protected void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.activity_main); 

    if (android.os.Build.VERSION.SDK_INT > 9) { 
     StrictMode.ThreadPolicy policy = new StrictMode.ThreadPolicy.Builder().permitAll().build(); 
     StrictMode.setThreadPolicy(policy); 
    } 

    uri = URI.create("http://www.pandorabots.com/pandora/talk-xml?botid=e80e92407e341007"); 
    server = new XMLRPCClient(uri); 
    editOne = (EditText) findViewById(R.id.editText1); 
    textOne = (TextView) findViewById(R.id.textView1); 
    ButtonOne = (Button) findViewById(R.id.button1); 

    textSatu.setText(getDataMethod("hi")); 
} 

@Override 
public boolean onCreateOptionsMenu(Menu menu) { 
    // Inflate the menu; this adds items to the action bar if it is present. 
    getMenuInflater().inflate(R.menu.main, menu); 
    return true; 
} 


private String getDataMethod(String num) { 
    String text = ""; 
    try { 
     Log.w("Running server.call", "prosess"); 
     Object[] data = (Object[]) server.call("input", num); 
     Log.w("server.call Run", "finish"); 
     Log.w("Run HashMap", "prosess"); 
     for(Object o: data) { 
      HashMap map = (HashMap) o; 
      Log.w("HashMap Berjalan", "Error"); 
      text = text + "'that' => " + map.get("that") + "\n\n"; 
     } 
    } catch (XMLRPCException e) { 
     Log.w("XMLRPC Test", "Error", e); 
     text = "XMLRPC error"; 
    }  
    return text; 
} 


} 

但我得到錯誤。這就是說：org.xmlpull.v1.XmlPullParserException：expected：START_TAG {null} methodResponse（position：START_TAG @ 1：45 in java.io.InputStreamReader@41174280）

任何人都可以幫助我嗎？請。

這裏是一個不需要XMLRPCClient的解決方案。重要的是在與bot首次交互時捕獲客戶ID，然後將custid的值與每個後續事務一起發回。機器人所使用的客戶ID記住與會話線程相關聯的局部變量，如姓名，年齡，性別，主題等
