I want to add authentication/security for my android air application ????

Can anyone please help me to solve these requirement for my android air application which is generated from Adobe flash cc

1. Is there any choice to add authentication??

2. Is there any choice to generate application for single user?? ( copy protection)

3. Is there any choice to add expiry period for application like 2 months or 3 months??

4. serial number process to activate application??

Thanks&Regards
