@micahmo feel free to test this out on Android to make sure all the permissions are enabled for storage!

Will do! If it works on Android, are you ready to merge?

[hjiangsu]

Yeah, I think this can be merged in if its all good - I just have the settings placed in the general settings, but we can move that around after if needed!

Just a quick update on this. Unfortunately it's crashing on Android for me with this error.

android.content.ActivityNotFoundException: No Activity found to handle Intent { act=android.intent.action.CREATE_DOCUMENT cat=[android.intent.category.OPENABLE] typ=json (has extras) }

Need more time to investigate!

[micahmo]

Alright, I tracked this one down! Apparently the issue was related to the MIME type, and just json isn't "valid", it wanted application/json. The clue was from here.

I made this change and it works great on Android now! Just to ensure it didn't break anything, I think you should test it again on iOS @hjiangsu. Then we're good to go!

@micahmo Just tested it on iOS and it seems to be working as intended!
