HttpClient post in Android

To post the data to the server, to get the data from the server which is stored in remote database, we can use HttpClient for webservice requests.
 call HttpClient ,
HttpClient  client = new DefaultHttpClient();
Here is the example for HttpClient for posting the data, getting response from the server.

public class MainActivity extends Activity {
    TextView tv;
    String text;
    Button b;
    DefaultHttpClient client; 
    @Override
    protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    setContentView(R.layout.activity_main);
    tv     = (TextView)findViewById(R.id.textView1);
     text     = "";
    }
     public void callWebService(View webService)
    {
      try {
            postData();
        } catch (JSONException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
           }
  public void postData() throws JSONException{ 
        // Create a new HttpClient and Post Header
        client = new DefaultHttpClient();
        HttpPost httppost = new HttpPost("http://192.168.0.1:8080/webservice/latest");        
        JSONObject json= new JSONObject();
           try {
            // JSON data:
                json.put("datapost",subJSON);
         StringEntity entity = new StringEntity(mainJSON.toString(), HTTP.UTF_8);
            httppost.setHeader("Content-Type","application/json");
            httppost.setEntity(entity);
            // Execute HTTP Post Request
            System.out.print(json);
            Log.e("tag", text);
            HttpResponse response = client.execute(httppost,localContext);
                      // for JSON:
            if(response != null)
            {
                InputStream is = response.getEntity().getContent();

                BufferedReader reader = new BufferedReader(new InputStreamReader(is));
                StringBuilder sb = new StringBuilder();

                String line = null;
                try {
                    while ((line = reader.readLine()) != null) {
                        sb.append(line + "\n");
                    }
                } catch (IOException e) {
                    e.printStackTrace();
                } finally {
                    try {
                        is.close();
                    } catch (IOException e) {
                        e.printStackTrace();
                    }
                }
                text = sb.toString();
            }
            tv.setText(text);

 }catch (ClientProtocolException e) {
            // TODO Auto-generated catch block
        } catch (IOException e) {
            // TODO Auto-generated catch block

WebView in Android

WebView is a class which is an extention of View class. Using Webview, we can display webpages in the mobile browser.

To add webview to your application, declare internet permission in manifest file and add WebView to xml.
To load webpage in WebView, use loadUrl

WebView wb=(WebView)findViewById(R.id.webView1);
        wb.loadUrl("http://www.mobengineers.com");
      
You must enable javascript in your webview to load javascript in the page.

To bind interface between Javascript code and android code, then use
        webview.addJavascriptInterface(new WebAppInterface(this), "Android");

To store user data in the browser, we have to use cookies, so that the browser data it does not share.

android.webkit.CookieSyncManager  class to manage all cookies.

To use this, 1st create one instance,

cookieSyncManager.createInstance(context);

setup sync call

to start

cookieSyncManager.getInstance().startSync();

to stop

cookieSyncManager.getInstance().stopSync();

to get sync instantly,

cookieSyncManager.getInstance().Sync();

sample webview example here

package com.example.demo1;

public class MainActivity extends Activity {

    public class WebAppInterface { Context mContext;

    WebAppInterface(Context c) {
        mContext = c;
    }


    public void showToast(String toast) {
        Toast.makeText(mContext, toast, Toast.LENGTH_SHORT).show();
    }

}

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
       
        WebView wb=(WebView)findViewById(R.id.webView1);
        wb.loadUrl("http://www.mobengineers.com");
        WebSettings ws=wb.getSettings();
        ws.setJavaScriptEnabled(true);
       // wb.addJavascriptInterface(new WebAppInterface(this), "Android");
        wb.setWebViewClient(new WebViewClient());
       
    }

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        // Inflate the menu; this adds items to the action bar if it is present.
        getMenuInflater().inflate(R.menu.activity_main, menu);
        return true;
    }
    private class MyWebViewClient extends WebViewClient {
        @Override

                return false;
            }
            Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse(url));
