title: android LicenseValidator : Signature verification failed
body: <p>I'm having a problem with the LVL in one app. </p>
  
  <p>We have around 10 Apps in that we are using License check, but today only one App is not working. Its showing Signature Verification Failed error. All 10 apps are using the same licensing library, apart from one app all are working perfectly fine. Not getting why its not working. The Key I'm using is definitely correct!  </p>
  
  <p>The error I get in logcat is: </p>
  
  <pre><code>12-12 15:22:07.000: E/LicenseValidator(6783): Signature verification failed.
  </code></pre>
  
  <p>And the dontAllow() function of the LicenseCheckerCallback is run. </p>
  
  <p>I'm testing the apps on a Nexus One.</p>
