Is the file under "res" secure enough after compile?

Issue

I want to retrieve some data from a xml file under res/xml. (kind of like reading plist)

Is it safe to save some confidencial information in that file? Is it possible to get the xml file after compiling?

Is there a better way to preload data?

Solution

No, it's not safe to save your confidental info there.

There are reverse engineering-tools .apk that can retrieve both resouces and source code. This one for instance http://ibotpeaches.github.io/Apktool/

You can use proguard to obfuscate your source code, but it won't protect your resources.
