Need some help with persistance on Android

I need help fixing an issue with persistance in my code. I'm new to Android and I'm guessing have missed something importnat.

I'm trying to preserve user check box selection between sessions in an internal json file:

1. In MainActivity on load I try to read internal [url removed, login to view] file on a phone, if the file does not exist I'm loading a template object from a resource and saving that json as a internal file called items.json. Then I pass my JSON object to [url removed, login to view]

2. Every time I click a check box an item I invoke setOnClickListener in MainViewAdapter.java. I update json object with checked state and I save the json to a [url removed, login to view] internal file.

ISSUE: even though I have no errors and I see the checked state of a json object change when saving, on reload my updates are gone and no longer visible when I re-load the same file I just saved during a previous session.

Missing something simple just can't see it.

Thank you
