您code可能是首先简化了，我建议你使用这个机器人库：
http://loopj.com/android-async-http/ ，让您尽样的HTTP请求。​​

Your code could be first of all simplified, i suggest you to use this android library: http://loopj.com/android-async-http/ which allows you to make every kind of HTTP requests.

在你下载了它，你应该很明显它导入到你的项目。

After you downloaded it you should obviously import it in your project.

code。与实施的Andr​​oid异步HTTP客户端

Code with Android Asynchronous Http Client implemented

public class Final extends Activity {

AsyncHttpClient client = new AsyncHttpClient();
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_final);


    Button btnSend = (Button)findViewById(R.id.BtnSend);



    btnSend.setOnClickListener(new OnClickListener(){

    public void onClick(View arg0){

            TestReceiver();


        }
    });



void TestReceiver()
{

        //ALERT MESSAGE
        Toast.makeText(getBaseContext(),"Please wait, connecting to server.",Toast.LENGTH_LONG).show();
        String Value="Kevin";

        String url = "http://echogame24.comli.com/Receiver.php?action="+Value;


        client.get(url, new AsyncHttpResponseHandler() {
            @Override
            public void onSuccess(String response) {
                Toast.makeText(getBaseContext(),"Request made successfully.",Toast.LENGTH_LONG).show();
            }
        });

    }
}
