title: implementing In-app Billing in the emulator
body: <p>I have been reading about "implementing In-app Billing" for an android application, and the documentation says that is not possible to test the application in the emulator. Is that true?</p>
  
  <p>I don't have a "mobile data plan" with the mobile I'm developing, so I try to connect the mobile through my PC via USB, but because my PC is behind a proxy, I can't connect to Internet.</p>
  
  <p>What could I do?</p>
  
  <p>Thanks in advance</p>
