Additional feature requires in android app source code (eclipse)

I have a small project [login to view URL] summary of the project is: I have an android app (eclipse) which displays tv channels. The streams of the channels are stored in a mysql database. There is a page which lists icons for each channel and when a user clicks it, a menu popups. In this menu I need an additional feature called "add to favorites" which will add this channel plus icon to a new page which should be created as well by you. The user also can get access to this page when clicking the favorite icon in the action bar. The icon isn't in the action bar yet but it is available in the eclipse source code. Your added code for the favorites should also check the database if the channel is still available and if not it should remove the icon from the favorites list. The user also should be able to manually remove a channel on his own from the favorites list. I will provide the Eclipse project and an example of the Mysql database that you can see which data the app fetches from the DB.
