title: Paypal donation in android application
body: <p>I know several topics have come across about this subject, but I'd like to be sure and know what is allowed once and for all.</p>
  
  <p>I'm planning on releasing an app in the android market for free. I'd like to add a donate button in the menu which links to my paypal donate link. Donating will not cause any changes to the app like adding extra functionality.</p>
  
  <p>Is this allowed?</p>
  
  <p>I've read it is on several pages, claiming that you can do this as long as you don't add extra functionalities or other things to the app. Others say you just can't get around the 30% fee.</p>
  
  <p>I wan't to release my app on the official android market so releasing it by myself or on another market is no option.</p>
  
  <p>Thank you</p>
