I'm in the middle of making a wallpaper app for android and I'm have a problem with Muzei support and hoping someone here can help me see what I'm missing.
I have a JSON file which my app uses to get the wallpaper URLs and display the pictures from. It works fine and it gets the right images. However if I update the JSON with more entries and more images then the Muzei extension still uses the old database. I was thinking that maybe it caches the database and just doesn't update it for whatever reason. The only way to get it to use the updated JSON file is to clear the data of my app and set a different extension in Muzei and the reset Muzei with my extension. Which would not be very user friendly.
Probably just being blind but help would be appreciated.

Not sure if I need any other code in here or not and the logcat doesn't say anything, it's as though it's it's working as normal. If you need to see more code just let me know.
Thanks for any help.
