我有我的應用程序的按鈕，我希望當我按下按鈕的應用程序發送一個字符串到websrvice和得到的結果，這是我的代碼：安卓：在按下按鈕獲得java.io.EOFException的
btn = (Button) findViewById(R.id.button_add_to_cart);
btn.setTypeface(typeface);
btn.setEnabled(false);
btn.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
try {
env = new SoapSerializationEnvelope(SoapEnvelope.VER11);
env.dotNet = false;
env.xsd = SoapSerializationEnvelope.XSD;
env.enc = SoapSerializationEnvelope.ENC;
env.encodingStyle="utf-8";
request = new SoapObject("customWebService",
"add");
request.addProperty("sessionID", sessionId);
env.setOutputSoapObject(request);
androidHttpTransport = new HttpTransportSE(
"http://mywebsiteee.com/WebService/server.php?wsdl/",
60000);
androidHttpTransport.debug = true;
androidHttpTransport.setXmlVersionTag("<?xml version=\"1.0\" encoding=\"UTF-8\"?>");
androidHttpTransport.call("", env);
SoapObject result = (SoapObject)env.bodyIn;
String Test1 = result.getPropertyAsString(0);
String str = env.bodyIn.toString();
String s = Test1;
byte[] b = s.getBytes("UTF-8");
s = new String(b, "UTF-8");
try {
JSONObject jsonObject = new JSONObject(Test1);
s = jsonObject.getString("result");
} catch (JSONException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
} catch (IOException e) {
e.printStackTrace();
} catch (XmlPullParserException e) {
e.printStackTrace();
}
我的問題是，當我按下按鈕，我第一次得到這個錯誤：
java.io.EOFException的
這是完整的日誌：

但過了一段時間我按下按鈕或當我長時間按下它時，它的工作正常！ 任何機構可以幫助我知道爲什麼會發生這種情況？
