Android “Resources” Security

问题:

I am building an Android app in which client is selling some mp3 files. Now my question is, when I copy these files in the resources folder, will they will be exposed when someone will explore the file system?

The reason why I am asking this question because I have seen application on Android market which can let you explore the android file system (you can also do this by attaching your device to your PC) and you can check what's in inside the application directory.

So if this is possible, how I can make sure my resources are secure?

Thanks.

Yes.

You can't.

What you're asking for would only be possible on a trusted computing (a.k.a. treacherous computing) platform, which Android is not.
