title: Check android purchase status but return the purchase token was not found
body: <p>I refered <a href="https://developers.google.com/android-publisher/api-ref/purchases/products/get" rel="nofollow">google play android api</a> to check the purchase and consumption status of an in-app item. 
  For some orders, I can get right result,but some return the error as below:</p>
  
  <pre><code>error: {
  errors: [
  {
  domain: "global",
  reason: "purchaseTokenNotFound",
  message: "The purchase token was not found.",
  locationType: "parameter",
  location: "token"
  }
  ],
  code: 404,
  message: "The purchase token was not found."
  }
  </code></pre>
  
  <p>Purchase token is provided by google, does it can be faked?</p>
  
  <p>I found if I cancel the google order, then check the purchase status,it will return the purchase token was not found. if not, i will get the right purchase status.</p>
  
  <p>Hope somebody can help.</p>
