I don’t want to pollute this forum but I’ve searched the internet for days now and with no results.
I have a problem with installing an ionic application on android devices below 4.3.
ionic start myApp blank
ionic platform add android
cordova plugin rm org.apache.cordova.console
ionic build android
sign apk using jarsign
upload apk to android phone
Installs fine on android 4.3 but not 4.2 or lower.
