title: Published Android apk gives error "Package file was not signed correctly"
body: <p>I recently uploaded my application to the android market however it's refusing to run when downloaded due to the error</p>
  
  <blockquote>
    <p>Package file was not signed correctly</p>
  </blockquote>
  
  <p>I first published the packet using eclipse, right click export, creating a keystore then publishing, however it refuses to work.</p>
  
  <p>I then downloaded the keytool and jarsigner and used them to sign an upgrade which I posted instead. However this gives the same error.</p>
  
  <p>I have no idea what I've done wrong, and since I cannot delete the application I cannot try and start again can anyone help me?</p>
  
  <p>Thanks</p>
