Can we have in-app purchase and subscription options in android apps? If yes, how do we implement it?
Try MoVend:https://movend.com/. It provides different purchase options like paypal, in-app billing, etc.
Subscriptions are now supported with in-app billing.

It's called In-App Billing on Android:

I don't believe it supports a subscription model if you use this system.
Bachbill supports in-app billing for Android. We implemented it using Tic-tac-to as an example and the code and more information are available in this link: http://wiki.bachbill.com/confluence/display/devreference/Android+example+3.+Adding+In-app-purchase+to+the+Tic-tac-toe+game
