我是一个Android开发的新手,我测试时通过http连接发送短信并得到一个返回字符串时有这个错误消息。下面是HTTP API:我想通过android的http连接
http://server:port/CreditCheck/checkcredits?username=xxxxx&password=xxxx
我得到java.io.ioexception
,我不知道如何进一步跟踪,它真的让我头疼。

下面是我的按钮onClicklistener
public void onClick(View v) {
Sender s = new Sender("server", port, "username", "password", "test for unicode", "1", "0", "23481111111", "Update");
switch(v.getId()){
case R.id.btnSaveSettings:
Toast.makeText(getActivity(), s.submitMessage().toString(), Toast.LENGTH_SHORT).show();
break;
case R.id.btnBalance:
Toast.makeText(getActivity(), s.checkBalance().toString(), Toast.LENGTH_SHORT).show();
break;
default:
Toast.makeText(getActivity(), "No button Captured", Toast.LENGTH_SHORT).show();
}
}
请帮我什么我做错了调用脚本!
@Angad我编辑了代码,下面是它看起来像和我得到的错误。
我的调用方法
public String checkBalance() {
try {
HttpClient client=new DefaultHttpClient();
HttpPost request=new HttpPost("http://" + this.server + ":" + this.port + "/CreditCheck/checkcredits");
BasicNameValuePair username=new BasicNameValuePair("username", this.username);
BasicNameValuePair password=new BasicNameValuePair("password", this.password);
List<NameValuePair> list=new ArrayList<NameValuePair>();
list.add(username);
list.add(password);
UrlEncodedFormEntity urlentity=new UrlEncodedFormEntity(list);
request.setEntity(urlentity);
HttpResponse response=client.execute(request);
HttpEntity entity=response.getEntity();
String tmp=EntityUtils.toString(entity);
return tmp;
}catch(Exception ex){
ex.printStackTrace();
return ex.toString();
}
}
我的onclick实施操作方法checkBalance()
public void onClick(View v) {
Sender s = new Sender("111.211.211.111", 8080, "user",
"pass", "test for unicode", "1", "0", "234811111111", "Update");
// TODO Auto-generated method stub
switch(v.getId()){
case R.id.btnSaveSettings:
//this.savePreferences();
Toast.makeText(getActivity(), s.submitMessage().toString(), Toast.LENGTH_SHORT).show();
break;
case R.id.btnBalance:
Toast.makeText(getActivity(), s.checkBalance().toString(), Toast.LENGTH_SHORT).show();
break;
