在Webserver服务器中使用HttpGet执行命令

Question

大家好，我正在做一个远程控制我的RC汽车的项目，安装了adruino板和wifly shied。wifly shied设置了自己的set服务器，并设置了上、下、左、右移动的配置。然而，在我的android应用程序中，当我点击move forward按钮时，我遇到了如何访问when服务器的问题。下面是示例代码，我被困在那里了。

public class GetUrl extends Activity implements OnClickListener {

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);

        View forward_Button = findViewById(R.id.forwardButton);
        forward_Button.setOnClickListener(this);
}
@Override
    public void onClick(View v) {

        switch (v.getId()) {
        case R.id.forwardButton:
            HttpClient httpclient = new DefaultHttpClient();
            HttpGet httpget = new HttpGet("http://192.168.1.3/?LED=Fowd");
            HttpResponse response = httpclient.execute(httpget);

            break;

Answer 1

Java101: httpclient.execute(httpget)；抛出一个你必须捕捉的异常：

try {
  httpclient.execute(httpget);
} catch (ClientProtocolException e) {
  e.printStackStrace();
}
