title: Amazon in-app-purchases how to test payments
body: <p>I am working with Amazon In-app-purchases for Android on flash using native extentions. So, I have implemented purchase flow in sandbox ( I was using their file InAppSDK-SandboxData.json for debug). But now, I have an amazon account. I have created purchase items in my developers account, and I want to test flow of buying them.</p>
  
  <pre><code>String requestId = PurchasingManager.initiatePurchaseRequest(product_id);
  </code></pre>
  
  <p>but it throws an exception, it try to open file "InAppSDK-SandboxData.json", but I have deleted in hope that it will go to product servers, but it does not. I found that I can only make purchases when I will commit my app to Amazon app store((</p>
  
  <p>So, how can I test my real payments to product servers and how can I debug this process?? Thanks.</p>
