Building APK fails about cr-patcher HOT 4 OPEN

Now I was setting up the stuff from scratch on a Debian 8.

No chance to get the patcher run :(
Please can you tell me on which OS you had success with this solution,...

can be closed.
Its damn complicated to get all the dependencies running,...
zipalign was not working on my Debian 8 32bit from the "command line tools",...

But a happy end ;)

Just still dont know why patching is neccessary,... Isnt it possible to implement the decryption into the proxy, even if the apk is not patched?

@erichegit Patching is necessary to make the apk connecting to supercell's servers through the proxy

Because nobody knows Supercell's private key ;)
