android - Muzei database doesn't update when I update external JSON -

-

i'm in middle of making wallpaper app android , i'm have problem muzei support , hoping here can me see i'm missing.

i have json file app uses wallpaper urls , display pictures from. works fine , gets right images. if update json more entries , more images muzei extension still uses old database. thinking maybe caches database , doesn't update whatever reason. way use updated json file clear data of app , set different extension in muzei , reset muzei extension. not user friendly.

probably being blind appreciated.

            }         }     } }

not sure if need other code in here or not , logcat doesn't anything, it's though it's it's working normal. if need see more code let me know.

thanks help.

basically right , being stupid , missing simplest thing, didn't have artsource.java.

in wallsdatabase.java wasn't updating database_version. leaving @ 1 , when updated app didn't bother update database because version same.

so change value of private static final int database_version = 1 higher number , should work great.

simple mistake easy 1 make guess.
