java - Deprecated methods in Android Studio (AS) 1.1.0 (and Eclipse Luna) "Settings Activity" -

my app have couple of checkboxes i'd rather user didn't have re-check each time app chased memory. i've been reading preferences.

i'm not sure i've seen complicated "a modern fragment-based preferenceactivity", looking guidance/example 1.1.0, got code total of 9 references in 4 hunks of code addpreferencesfromresource, getpreferencescreen, , findpreference, of carry blurb:

this method deprecated in api level 11. function not relevant modern fragment-based preferenceactivity.

to have code presented deprecated code 2 ides 1 thing; there's no indication of each method has been replaced (but there's nothing replacing it, happens).

would hard produce "a modern fragment-based preferenceactivity"? if so, guess i'm right complexity.

am missing something? supposed write/extend deprecated code? turn off compiler checking of deprecated stuff?

does know of nice tutorial (or example of) simple (like 2 checkboxes) "modern fragment-based preferenceactivity"? or saves preferences isn't deprecated?
