Some of my app's preferences could use some more explanation than the scarce space available for the summary. Sadly, there doesn't seem to be support from the system, like an optional help button that shows a longer text. How do you solve this problem? The first thing that comes to mind is an addional custom "preference" like "more information to above entry" that opens an AlertDialog with the help text, but that's not really nice for both user (two entries for the same preference) and the developer (manual work to do in the PreferenceActivity). A bit nicer for the user, but way more work for the developer would be custom dialogs for each preference with more text and/or a help button. Is there a better solution or even an officially recommended best practice?
