java - Is an Android app which uses local JSON files to store data vulnerable? -

my android app uses plain text json files store data. such files saved private folder of app, e.g. android/data/com.example.app/. know if app vulnerable such kind of files around. info in files not sensible or secret, , not processed javascript (they parsed json java methods); concerned malicious json code injected , mess app or user's device. possible?

by default, info store private folder neither accessible user nor other applications. see documentation on android developers website this: http://developer.android.com/guide/topics/data/data-storage.html#filesinternal

however, mentioned smr, if device has been rooted info available user , might compromised apps user has given root permission to. it's minority of users rooted , should more or less know they've gotten , they're actions can do. it's decide if it's worth effort out these special cases.

but default info should safe , sound.
