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…
