How to protect my sources?

[Android Central Question]

Hi.
I'm new to android development. Making my first game. But I wonder how to protect my source code from steal?
I'm teaching obfuscation and some services, such dex protector and appwatermark.
First one, seams to be very difficult. The second one - too easy and it's frighten.

Can you help me with that, please?
