title: Android In App Billing v3: get prices doesn't work for unmanaged items
body: <p>I am using the standard Android IAB v3 code to detect prices of items at startup.</p>
  
  <p>However it is not returning any SkuDetails for my unmanaged items, only for the managed items.</p>
  
  <p>Any ideas?</p>
  
  <pre><code>static IabHelper.QueryInventoryFinishedListener mGotInventoryListener = new IabHelper.QueryInventoryFinishedListener()
  {
      public void onQueryInventoryFinished(IabResult result,
              Inventory inventory)
      {
          if (result.isFailure())
          {
              return;
          }
  
          for (String sku : new String[]
          { "unmanaged_item1", "managed_item1" })
          {
              if (inventory.hasDetails(sku))
              {
                  SkuDetails details = inventory.getSkuDetails(sku);
                  Log.d(TAG, sku + ": " + details.getTitle() + "," + details.getPrice());
              }
          }
      }
  };
  </code></pre>
