Ha, same. I think I was eventually trying to hook into kernel-level functions and do it that way (I was using the Android client) but couldn't get far there either, though I think it's technically doable. IIRC, they were using some kind of vtable patching protection around kernel functions to ensure integrity.

I built anti-cheat software (and hardware) before, and it felt like anti-cheat level security. I had an axe to grind with Snapchat, as they rejected me after the first interview round :P
