Android读取php返回的json格式数据

[php]代码库

$array = array(
  'username'=>'http://yuncode.net',
  'password'=>'http://yuncode.net',
  'user_id'=>1
);
echo json_encode($array); 


private void startUrlCheck(String username,String password)
{
	HttpClient client = new DefaultHttpClient();
	StringBuilder builder = new StringBuilder();

	HttpGet myget = new HttpGet("http://10.0.2.2/Android/index.php");
	try {
		HttpResponse response = client.execute(myget);
		BufferedReader reader = new BufferedReader(new InputStreamReader(
		response.getEntity().getContent()));
		for (String s = reader.readLine(); s != null; s = reader.readLine()) {
			builder.append(s);
		}
		JSONObject jsonObject = new JSONObject(builder.toString());
		String re_username = jsonObject.getString("username");
		String re_password = jsonObject.getString("password");
		int re_user_id = jsonObject.getInt("user_id");
		setTitle("用户id_"+re_user_id);
		Log.v("url response", "true="+re_username);
		Log.v("url response", "true="+re_password);
	} catch (Exception e) {
		Log.v("url response", "false");
		e.printStackTrace();
	}
}

其中http://10.0.2.2为Android访问本机url的ip地址。对应电脑上测试的http://127.0.0.1

另外执行代码时会抛出异常

java.net.SocketException: Permission denied

此为应用访问网络的权限不足 在AndroidManifest.xml中，需要进行如下配置：
<uses-permission Android:name="android.permission.INTERNET" />
就加在
</manifest>
之前就好了
然后测试通过。
