I am building an "About" dialog that will appear as a PreferenceFragment in my application. I believe I have everything "wired" properly as I'm getting a toast comment when I load my About preference fragement, however, the data I load in my SimpleAdapter doesn't appear. Below are my various code bits that should help. I am quite new to Android development, so if you have other ideas about how I can go about achieving my goals (a multicolumn listview to display information about the application (company, version, etc.), then please let me know where I can go to get examples, etc. Thanks in Advance!!!
