Cordova icons and splash screens are native resources declared in /src-cordova/config.xml. The required files and declarations depend on the installed cordova-android and cordova-ios versions.
If you discover one file that is new or missing, please open an issue.
Icon Genie CLI
TIP
We highly recommend using the Icon Genie CLI, because it consumes a source icon and automatically clones, scales, minifies and places the icons in the appropriate directories for you. When needed, it also tells you what tags you’ll need to add to your /index.html file.
Quickly bootstrap the necessary images with Icon Genie CLI. For a complete list of options, please visit the Icon Genie CLI command list page.
icongenie generate -m cordova -i /path/to/source/icon.png [-b /path/to/background.png]Manual instructions
Unless you are using Icon Genie CLI, replace the generated resources and keep their config.xml declarations aligned with the requirements of each installed Cordova platform. Current Cordova platforms provide splash-screen handling; install cordova-plugin-splashscreen (in /src-cordova) only when an older platform version explicitly requires it.
And here is part of what your config.xml should look like:
