title: Getting response code as 5 in inapp billing consumption android
body: <p>Actually i am trying to do In-App Purchase in android and i have downloaded the trivial drive from android sdk. I can do the purchase sucessfully by calling launchPurchaseFlow method but the problem is when i try to consume the product by calling consumeAsync method im getting the response code as 5 (Developer Errror).
  this is the code i am executing after the purchase was sucessfull</p>
  
  <pre><code>mHelper.consumeAsync(inventory.getPurchase(SKU_GAS), mConsumeFinishedListener);
  </code></pre>
