Until now I have been using Ionic Pro to do my build for app store process but now want to do it outside of that as I'm paying money each month just to do something I should be able to do myself.

When I upload my signed and zipaligned file to the store it gives me an error saying that it must be signed with the same file.

​

I have found several varying instructions on how to do the process, does anyone have a step by step guide that works?

​

my current process is;

​

ionic cordova build android --prod —release

keytool -genkey -v -keystore <appname>.keystore -alias <appname> -keyalg RSA -keysize 2048 -validity 10000

jarsigner -verbose -sigalg SHA1withRSA -digestalg SHA1 -keystore <appname/version>.keystore app-release-unsigned.apk <appname>

./zipalign -v 4 app-release-unsigned.apk <appname/version>.apk
