Question

I am working on android for the first time, I just want to connect my android app with node server on a button click. my node server is
在localhost上运行，我的手机也连接到同一个网络。有没有可能连接我的Android应用程序与运行节点服务器。我要做的就是调用只有服务器的路由打印＆＃34; Hello world＆＃34;在console.log的服务器中。如果可能请帮我解释一下代码。感谢。

**This is my ooClick function in android.**
public void sendMessage(View view) {

         name     =  (EditText)findViewById(R.id.name);
         email      =  (EditText)findViewById(R.id.email);
         phone       =  (EditText)findViewById(R.id.phone);
         address       =  (EditText)findViewById(R.id.address);


         try {
             String nme    = URLEncoder.encode(name.getText().toString(), "UTF-8");
             String eMail  = URLEncoder.encode(email.getText().toString(), "UTF-8");
             String ph   = URLEncoder.encode(phone.getText().toString(), "UTF-8");
            String add    = URLEncoder.encode(address.getText().toString(), "UTF-8");



            // Create http client object to send request to server
            HttpClient Client = new DefaultHttpClient();

            // Create URL string

            String URL = "http://192.168.0.183:3000/save?text1="+nme+"&text2="+eMail+"&text3="+ph+"&text4="+add;
            //Toast.makeText(getBaseContext(),"Please wait, connecting to server."+URL,Toast.LENGTH_LONG).show();
            try
            {
                          String SetServerString = "";

                        // Create Request to server and get response

                          HttpGet httpget = new HttpGet(URL);
                         ResponseHandler<String> responseHandler = new BasicResponseHandler();
                         SetServerString = Client.execute(httpget, responseHandler);

                          // Show response on activity 

                         //content.setText(SetServerString);
                         Toast.makeText(getBaseContext(),"response"+SetServerString,Toast.LENGTH_LONG).show();
             }
           catch(Exception ex)
              {
               Toast.makeText(getBaseContext(),"fail",Toast.LENGTH_LONG).show();
               }
        } catch (UnsupportedEncodingException e) {
            // TODO Auto-generated catch block
            Toast.makeText(getBaseContext(),"response",Toast.LENGTH_LONG).show();
        }


**This is my function in node server**


app.get('/save', function(req, res){

        var text1= req.param('text1');
        var text2= req.param('text2');
        var text3= req.param('text3');
        var text4= req.param('text4');
console.log(text1+' '+text2+' '+text3);

});

我只想在控制台中打印文本。

您应该考虑使用Retrofit库。这使得从Android应用程序进行HTTP调用变得非常容易。此外，您还需要外部IP地址或服务器名称才能通过网络访问数据。＆＃34;本地主机＆＃34;始终指的是运行软件的当前计算机。对于您的桌面，＆＃34; localhost＆＃34;是桌面;对于您的Android设备，＆＃34; localhost＆＃34;是Android设备。
