I change image in resource but its not working
Run ionic resources from CLI
After that following folder will be created
resources > android
resources > ios
Add icon.png and splash.png file in resource folder and run ionic resources command again.
It will create icon and splash screen automatically and also add in config.xml file. Nothing to do manually. Ionic will do everything automatically for you.
Change default splash screen and spin
These are Cordova resources. You can replace icon.png and splash.png and run
ionic cordova resources to generate custom icons and splash screens for your
ionic cordova resources --help for details.
