Published Android apk gives error "Package file was not signed correctly"

Question

I recently uploaded my application to the android market however it's refusing to run when downloaded due to the error

Package file was not signed correctly

I first published the packet using eclipse, right click export, creating a keystore then publishing, however it refuses to work.

I then downloaded the keytool and jarsigner and used them to sign an upgrade which I posted instead. However this gives the same error.

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?

Thanks

Answer 1

This error usually occurs because you are trying to push an update which was signed with a different key than you used in the initial submission. You need to find the key you used the first time you published the application and use this to sign the update.

Answer 2

You have your debug copy still installed on your device most likely. Now you have downloaded a different copy of the same app and it's causing this error.

Uninstall the app completely from your device. Then download it from the market again and it should work.

Also, please work on that 0% accept rate you have.
