title: What are the possibilities to get this error code 3 in InApp purchase?
body: <p>I am using InApp V3 code for in-app purchases in my application , i am getting this error <code>BILLING_RESPONSE_RESULT_BILLING_UNAVAILABLE</code> and <code>error value :3</code> when Google account is not available in device. I want to know is there any other possibilities to get this error, because when i get this error i need show a popup to the user with some data. If this is causing because of Google account not available on device i will show the dialog with related text. this is the code i am using  </p>
  
  <pre><code>mHelper.startSetup(new IabHelper.OnIabSetupFinishedListener() {
      public void onIabSetupFinished(IabResult result) {              
          if (!result.isSuccess()) {
                  // error here               
              return;
          }
      }
  });
  </code></pre>
