问题
I was trying SharedPreferences and everything works fine. According to the tutorial, after I change some preferences, I should find a folder named shared_prefs and a XML file which contains my preferences under the data folder in DDMS perspective. But mine is empty, why? Btw, I am debugging with real Android phone. Thx.

If your SharedPreferences are private, you need to be root on your device to see what is in this folder.
