Protecting content in a jar file

Question

I made a mobile application. When you extract the jar file, the resource files are visible (text files and image files). Is there a way to protect content files? I'm not worried about reverse engineering bytecode. I need to protect the content. Thanks:)

Answer 1

Only a 100% secure way to protect resource files is to drop them from the bank.

Really.

If your application should use your resources, you can store encrypted resources and then decrypt them as needed. But in the end, you are still passing data to an untrusted object.
