title: Amazon Web Services credentials may be exposed
body: <p>Recently Google provided alert to one of my Apps that</p>
  
  <blockquote>
    <p>Your Amazon Web Services credentials may be exposed. This exposure of
    your credentials could lead to unauthorized access to your AWS
    account, which may include associated excessive charges, and
    potentially unauthorized access to your data and your users' data.</p>
  </blockquote>
  
  <p>In the application, I'm using <strong>Amazon Product Advertising API</strong> to get and display the information related to some products.</p>
  
  <p>I'm using <strong><a href="https://github.com/agentgt/JavaAmazonProductAdvertisingClient/blob/master/src/com/evocatus/amazonclient/SignedRequestsHelper.java" rel="noreferrer">SignedRequestsHelper</a></strong> class provided by the Amazon to request the data.</p>
  
  <p>I need to know how can I <strong>protect my AWS keys</strong> in the <strong>Android</strong> app.</p>
  
  <p>Thanks.</p>
