App Not Installed ... please help

I have done an ionic cordova build android --prod --release … to build the apk

I have then gone through getting it signed with keytool, jarsigner, zipalign and apksigner.

I then ftp to my site, download it and try to install, then it just gives a simple error ‘App not installed’

I appreciate there is little information here, but has anyone had the same frustrating problem as me, because I do not know where to go next…

I’ve just fixed this guys. Always remember to uninstall the debugging version of the app on your device !
