推荐答案

首先添加下列内容清单。这是为了请求访问互联网的权限。

Firstly add following to your manifest. This is to request for a permission to access the internet.

<uses-permission android:name="android.permission.INTERNET" />

然后打一个Web服务最简单的方法是使用的HttpClient 与Android捆绑的：

Then the simplest way to hit a webservice is use the HttpClient bundled with android:

HttpClient httpclient = new DefaultHttpClient();
HttpResponse response = httpclient.execute(new HttpGet(URL));
StatusLine statusLine = response.getStatusLine();
if(statusLine.getStatusCode() == HttpStatus.SC_OK){
    ByteArrayOutputStream out = new ByteArrayOutputStream();
    response.getEntity().writeTo(out);
    out.close();
    String responseString = out.toString();
    //Whatever you wanna do with the response
} else{
    //Close the connection.
    response.getEntity().getContent().close();
    throw new IOException(statusLine.getReasonPhrase());
}
