Code obfuscation techniques?

Hi

As we are getting closer to the release, I started going through the apk/app files with our app.
Right now I’m looking at the apk and I can see resource.car file, which holds all our code.
The file is easily viewable by anyone who can press F3 in total/midnight commander and I can clearly see all of my variable names and values.

This way it’s trivial to modify the file and work around ad systems etc.
Since we’ve implemented some checksums to make sure [at least on some basic level] that no one interfered with our save games/stuff, I wanted to make it a little bit more difficult to read.

What do you use to “hide” your code and make it less easy to read?

Thanks,
