Menu Icon Is never shown

I am trying to show an icon in my action Bar. It is never shown.
My app is working fine. Even the function of the action bar button works as well. Am I missing Something ?
So Far. I added an action bar button as the following :
<menu xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
tools:context=".MyActivity" >
<item android:id="#+id/Refresh"
android:title="#string/Refresh"
android:icon="#drawable/refresh_icon"
android:orderInCategory="100"
app:showAsAction ="always"/>
<item android:id="#+id/action_settings"
android:title="#string/action_settings"
android:orderInCategory="100"
app:showAsAction="never" />
</menu>

I tried a lot of codes.
I figured out I have to make this code
<menu xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
tools:context=".MyActivity" >
to this one
<menu xmlns:android="http://schemas.android.com/apk/res/android" >
Even though it is giving me a strange error in the menu.xml but it works well

Navigation Drawer as the picture

I am building an app with a navigation drawer and fragment, i followed this tutorial to made it.
http://www.androidhive.info/2013/11/android-sliding-menu-using-navigation-drawer/
Now i have my navigation drawer like the result on the site, but i'd like to add a info button like this picture.
i don't know how to do it cause i only can add other item on the list view,but with the same xml layout ecc.
this is the layout holding the list view
<android.support.v4.widget.DrawerLayout

Wrap your Listview with a RelativeLayout and add to the RelativeLayout a ImageButton with the info-icon as source image. Align the button to the bottom of the parent RelativeLayout, add a OnClickListener to it and do whatever you want to do :)

You can try with listview footer. In your listview add footer and then add button control to footer.
Hope for help.

java.lang.NoClassDefFoundError: Fragment

I learning Android Sliding Menu using Navigation Drawer From http://www.androidhive.info/2013/11/android-sliding-menu-using-navigation-drawer/ .
This tutorial, sample code works started in android 3.0 or Honeycomb. I want to make it work on android 2.3.3. Then I followed this tutorial http://hmkcode.com/add-actionbar-to-android-2-3-x/. Here's what I've done:
I've changed the "Activity" to "ActionBarActivity".
Then change the "gettActionBar ()" to "getSupportActionBar ().
Sets Style on Manifest to "# style / Theme.AppCompat.Light
Well as adding Compabiltiy android v 7 Support

After I do the above, I still get the error java.lang.NoClassDefFoundError: info.androidhive.slidingmenu.HomeFragment and may be other fragment. So what should I do again? Thanks.. Sorry For my english
UPDATED
I have get Error android.view.InflateException: Binary XML file line #18: Error inflating class <unknown>
And this look error in NavDrawerListAdapter and XML drawer_list_item
Code NavDrawerListAdapter
#Override

if(navDrawerItems.get(position).getCounterVisibility()){
txtCount.setText(navDrawerItems.get(position).getCount());
}else{
// hide the counter view
txtCount.setVisibility(View.GONE);
}
return convertView;
}

In MainActivity.java
This
import android.app.Fragment;
must be
import android.support.v4.app.Fragment // same in all Fragments
Also should import
import android.support.v4.app.FragmentManager
Intead of this getFragmentManager() use getSupprtFragmentManager()
You can check a complete example #
Navigation Drawer with backword compatibility android

Today I followed tutorial that you did the same. I got the same errors for HomeFragment. I found the missing solution that is we also need to update the import
this
import android.app.Fragment;
to
import android.support.v4.app.Fragment;
for HomeFragment Class too.
It's worked for me.

what #Raghunandan mentioned was exactly correct and it should work, but I have used the same what he mentioned above, but still it din't works for me. Finally the Issue was crazy actually.
This crash happens sometime only with Samsung Device. If you are testing with that means use some other Device for once. when I just tried the same build with Moto, it works for me.

Open Webview when item in the side slide menu is clicked

I am trying to create a new activity when we click on the menu in side slide navigation. I have successfully created a new activity when i clicked on the menu but when a new activity is opening in WebView the side slider is diapperaing which I dont want.
As an example for this my application is same as a facebook application in which when we click on any item say "Newsfeed" it opens the activity but the slide navigation is still there.Kindly let me know hoe to achieve it.Thanks in advance.
This is my main activity code:

This is my activity code which is opening when I click on the item.As an example I have given activity code for only one activity:

setContentView(R.layout.fragment_home);
//WebView web = new WebView(this);
WebViewClient yourWebClient = new WebViewClient()
{

#Override

{
// This line we let me load only pages inside Firstdroid Webpage
if ( url.contains("DiarySystem") == true )
// Load new URL Don't override URL Link
return false;
// Return true to override url loading (In this case do nothing).
return true;
}
};
// Get Web view
// mWebView.setPadding(0, 0, 0, 0);
// mWebView.setInitialScale(getScale());
mWebView = (WebView) findViewById( R.id.webview ); //This is the id you gave
mWebView.getSettings().setJavaScriptEnabled(true);
mWebView.getSettings().setSupportZoom(true); //Zoom Control on web (You don't need this
//if ROM supports Multi-Touch
mWebView.getSettings().setBuiltInZoomControls(true); //Enable Multitouch if supported by ROM
mWebView.setWebViewClient(yourWebClient);
// Load URL
mWebView.loadUrl("http://103.241.181.36:8080/DiarySystem/addvehtogrp.jsp");
}//End of Method onCreate
