once the user scans the code on like a android wallet they get the coin
This is functionality you need to write into your program. QR codes are just stores for text data. If you write a specification for data storage then your app can sort it out when it scans it in. Maybe separate the relevant fields with a pipe | symbol or a comma? Then when you import it you can explode it into an array and work with it from there. The first variable could be the address, the second variable the amount, etc etc. I would be hesitant to hard code the amount into the QR code though because theoretically couldn't the amount increase/decrease as that address is used actively on the network? Accepting the QR code data as 'fact' would open your alt coin up to very VERY VERY easy scamming!
