Ive made a 1 hit kill hack for this Armies & Ants game. It only works on buildings though. I'm not too sure how combat works out late game, like if you have to fight the players standing army a la Castle Clash or not.

Don't be a dick bro.

Anyway, I haven't used bluestacks in quite a while, but I do recall having to run bluestacks in a virtual machine and then hacking the entire virtual machine from the host OS.  Bluestacks has (or at least had) insanely shitty memory management, often shitting all over the place, and the only way to get a grip on it was to hack everything.  That's probably changed now.  That aside, I do believe we're more setup for actual android hacking, not a shitty emulator.  Meh, I'll say that, then Kolonel will go out of his way to prove me wrong. ;)

When I apply a hack the game always crashes, is there something I might do wrong? 

its something to do with the way ive written the trainer. it seems to be less crashy if you press "apply hacks" then go back to the game process and wait for the trainer to finish there.

can you tell me anything about the android device you are using? especially android version and CPU.
if it isnt an arm7 it may have something to do with the endianness of the data stream, that is something i will have to look into.

You could always go fuck yourself. :D
