title: Error The apk must be signed with the same certificates
body: <p>My last key must have expired as when I tried to upload a new apk which I have done countless times before it has requested I load a new one. However, when I do I get the message above. I'm using the same project name and same key code file but even though I have created about half a dozen new apk files, I still get the same message. I've tried unpuiblishing my app to create a new one but it just tells me I already have an apk with the same name!
  Any help much appreciated</p>
