Exercise from lynda tutorial (notes app) show nothing

I'm doing the tutorial for the note taking app of lynda.com
(http://www.lynda.com/Android-tutorials/Building-Note-Taking-App-Android/122466-2.html),
until chapter 04 02 "data item", everything is working. But after this,
when i start getting info from the shared preferences, all i get is the
icon of the application. I even used the author's code without changes, to
no avail. But in the videos, everything works, and he gets a list of the
notes, as intended
In the log cat i have no infos, not a single info. I tried to use all
versions of the emulator, from 3.0 to 4.3
Here is the last code i managed to get working:

Here all i have is "Hello from Plain olnotes"
thanks for any input
