title: Can I use a PayPal donation button in my Android app in Google Play?
body: <p>My country is not supported by Google for a Merchant account so I can't publish paid apps. But I would like to get some donations from my users. I know that Google says in their policy that all payments must go through Google Play.</p>
  
  <p>How about donations? Can I use a donation button, which links to PayPal to accept donations? Or can I use the PayPal Mobile Payment Libraries (MPL) to accept donations?</p>
