getactionbar in fragment

I  call getactionbar in fragment but the function is not recognized. I search on Google and the solution is very simple.

ActionBar actionBar = getActivity().getActionBar();
   actionBar.setDisplayHomeAsUpEnabled(true);
 

NOTE 

You can control the behaviors and visibility of the action bar with the ActionBar APIs, which were added in Android 3.0 (API level 11). Remember!

launch skype from android application

My android app have a button and when user click that buttons, the app will launch skype from android application.

There is 2 steps

1) Check if skype is installed.

2) launch skype.



So, I write two function:

 public static boolean IsInstallSkype(Context context)
   {
       PackageManager pm = context.getPackageManager();
       boolean app_installed = false;
       try
       {
              pm.getPackageInfo("com.skype.raider", PackageManager.GET_ACTIVITIES);
              app_installed = true;
       }
       catch (PackageManager.NameNotFoundException e)
       {
              app_installed = false;
       }
       return app_installed ;
   }
// launch skype

if ((Utils.IsInstallSkype( v.getContext())))
   {
   Intent sky = new Intent("android.intent.action.VIEW");
   sky.setData(Uri.parse("skype:" + nickChat + "?chat"));
   v.getContext().startActivity(sky);
   }else
   {       
    Toast.makeText(v.getContext(),"You need to install skype", Toast.LENGTH_SHORT).show();
   }



And that 's it! happy code!

java.io.IOException: HTTP request failed, HTTP status: 500 SOAP Service

While I call web service from my android  app, I have an error.


 java.io.IOException: HTTP request failed, HTTP status: 500

 in my android app, I use ksoap lib.

I use php to test the service to know the service return true result.

<?php

/*
 * To change this template, choose Tools | Templates
 * and open the template in the editor.
 */
require_once('lib/nusoap.php');

$client = new nusoap_client('http://****.com/index.php?wsdl', true);


$result = $client->call('get_authors', array('ID' => '193'));


echo $result;
 ?>


And the service return null.

So fix again the service and the error on android app disapear. ^^
