Android4.0 calls the http interface php website api

(I just learned from cainiao) I read the online tutorial and wrote a simple HttpGet test. A bunch of errors are reported! Code: publicstaticStringgetApi (Stringurl) {Stringcontnull; HttpGethttpGetnewHttpGet (url); DefaultHttpClienthttpClientnewDefaultHttpClient ();

Code:

 public static String getApi(String url){               String cont = null;               HttpGet httpGet = new HttpGet(url);                                    DefaultHttpClient httpClient = new DefaultHttpClient();                try {                   HttpResponse httpResponse = httpClient.execute(httpGet);                    int reCode = httpResponse.getStatusLine().getStatusCode();                   if (reCode == HttpStatus.SC_OK) {                       cont = EntityUtils.toString(httpResponse.getEntity());                       return cont;                   }               } catch (ClientProtocolException e) {                   e.printStackTrace();               } catch (IOException e) {                   e.printStackTrace();               }               return "";    }

Report thread problems, read online information and say that from 2.3 onwards, the thread must be run in the thread, and then write a variety of online statements. Then, the system reports an error... then... wipe or not .... write it yourself ..... hope to help new users

Initialize in onCreate

Handler = new Handler (); // Of course, the private Handler handler must be defined at the top;

Then write in your trigger event

public void login_submit(View v){        new Thread(){            @Override            public void run() {                String url = "http://192.168.1.188/123.html";                 rs = HttpApi.getApi(url);                                handler.post(new Runnable() {                    @Override                    public void run() {                        Toast.makeText(login.this,rs,Toast.LENGTH_SHORT).show();                    }                });            }}.start();    }

Okay. Finally

Add a permission to allow Internet access in AndroidManifest. xml.

OK ....
