Code Repetition

I have to write a code to show "internet not available" dialogue box in few class files. As far as i know i need to write this code onCreate method only, but my concern is, code repetition. The code is as follows

onCreate()
{
  if(isNetworkStatusAvialable (getApplicationContext())) 
    {
        showAlertDialog(HomeActivity.this, "Internet Connection",
                    "You have internet connection", true);
    } 
    else
    {
        showAlertDialog(HomeActivity.this, "No Internet Connection",
                    "You don't have internet connection.", true);
    }
}//End of oncreate

showAlertDialog(................... )
 {

 }

In few class files the same code will be repeted. To avoid this, if i write separate class file and extend as "Extends" then i worried that onCreate method will be override through out the required class files, which consists of other things.

Any suggestions.

The application will crash with a SuperNotCalledException if an Activity overrides onCreate() without calling through to super.onCreate(), so as long as each Activity extends your base Activity you can be guaranteed that your implementation will be called.
