android - How to prevent the sensitive data used by app in android?

Question

As we all know Android app apk file can be drilled down to get the Java codes and resources. The sensitive data used to populate lets say list view used as arrays in Java files can be easily hacked.

What are the secure ways to do it?

I guess downloading XML or JSON file from the internet and using in app? Or there any other techniques?

Thanks in advance.
