you probably used a different keystore file, you need to uninstall the app and re-install it

yeah its advised to use one keystore file for you app and keep it safe and write down its password so you wont forget it for future updates for your application :) – Nouran S. Ahmad Oct 08 '15 at 07:41

the keystore should be same for two versions. in this case you have to un-install previous version and reinstall new version will fix the issue. or use the same keystore
