title: Android in-app purchase or Third party payment gateway
body: <p>We are going to build a mobile app for iOS and Android (might build a web app later) where users can upload videos and their friends and followers can watch them. The videos can be either free or also be tagged with a price. If I tag a video with $1 when uploading it, my friends and followers will have to first pay $1 to watch and after paying that $1 they can watch it any time after that.</p>
  
  <p>My client wants to use Authorize.net to do the payments. In iOS there are restrictions like we must use IAP for such feature. Similarly is there any restrictions on Android as well, that we must use Google In-app Billing or is it OK to use Authorize.net to do the payments?</p>
