please notice the error message you got

06-05 16:27:04.215: E/AndroidRuntime(14976): Caused by: java.lang.InstantiationException: can't instantiate class kostas.menu.rssreader.ListActivity$SampleListFragment; no empty constructor

this kinda means you HAVE to have an empty constructor for every Fragment class you create.

just add the empty constructor and everything should be just fine.

you mean something like `public ListActivity(){}` ? this returns me the same error – menu_on_top Jun 05 '13 at 13:33
no no no, the `Fragment` needs an empty constructor. add `public SampleListFragment(){};` – thepoosh Jun 05 '13 at 13:34
