• How to avoid reverse engineering of an APK assets folder resources items file? 2 answers

I've a question related to Data security in Android development. Right now i am working in an application where i need to keep an existing database in assets folder so App can copy it in to the internal writable location to avoid the large database download from server during first time installation. But unfortunately using APK decompiling tool one can view the files in assets folder included this database file. Is there a way to prevent my assets-files from being decompiled so Data security can be assured in my application. Any help would be highly appreciated. Thanks.

Simple answer is no . there will always be some way where a potential hacker can do it's tricks though you can make it harder by using some 'encryption' schemes mean you can encrypt your data with some special key,then with the key you can encode and decode your data so better place to keep things more secure is nactive libs means you using native(c,c++) code which should contain your sensitive data and generate libs, by doing this you are adding an another layer of encryption because reverse engineered native form of native libs are quite hard to read.
