android - Obfuscate/Encrypt SharedPreferences file possible? -


so, i'm interested in obfuscating sharedpreferences xml file of app, android lvl obfuscate it's license cahce data. conceivable? plenty of google-digging has yielded little results might address question. , i'm no cryptologist.

what other forms of encryption? end goal isn't try making xml bulletproof, want block out lower 90% of people refrain messing around if it's not in plain text.

don't believe possible, not without major modifications (possibly write own preferences implementation), , couldn't begin think how persuade android load preferences implementation.

the default sharedpreferences implementation isn't replaceable far can tell: if need encrypt lvl , either encrypt value write sharedpreferences xml, or create own entirely encrypted file , manage on disk yourself.
