Android app monthly charging

Question

I want to make an android app and the employer wants me to make this application to have a login mechanism. There will be a monthly charge for each user(let's say 2 $/month).First 3 days of use will be free.

Please tell me a way to do this. Should I use in-app billing? Or android market has something similar?

Thanks, Alex.

Answer 1

I'm assuming you have a server at your disposal (for login checks), so you could just have users pay for the account (which could be done both on the phone and online).

The login-server could then check if the account has paid or is in trial status
