I figured out a workaround. The CLI 4.1.2 build system will support this, but our build system (and the XDK) don't know about the XX and XXX sizes. However, Cordova CLI 4.1.2 does know about those sizes. So here's your workaround:
- copy your XX and XXX icons into your source directory (usually named www)\
- add the following lines to your intelxdk.config.additions.xml file
- see this Cordova doc page for some more details
Assuming your icons and splash screen images are stored in your source directory (www), then add lines similar to the intelxdk.config.additions.xml file (the precise name of your png files may be different than what I have here):
<!-- for adding xxhdpi and xxxhdpi icons on Android -->
<platform name="android">
<icon src="www/xxhdpi.png" density="xxhdpi" />
<icon src="www/xxxhdpi.png" density="xxxhdpi" />
<splash src="www/splash-port-xhdpi.png" density="port-xhdpi"/>
<splash src="www/splash-land-xhdpi.png" density="land-xhdpi"/>
</platform>
The precise names of your PNG files are not important, but the "density" designations are very important and, of course, the respective resolutions of your PNG files must be consistent with the Android requirements. Those density parameters specify the respective "res-drawable-*dpi" directories that will be created in your APK for use by the underlying Android OS. NOTE: I've added the splash screen references for example, you don't need to use those.
You can continue to insert icons into your app using the XDK, or do all of them this way. Since there is no way to remove icons from the Projects tab (something I've been asking for), you'll have to remove them from the <project-name>.xdk file directly (it's up to you).
Give it a try and let me know how well it works. I did only a quick test and confirmed they show up in the right places in the APK file, I did not do a complete test, but this should work based on the results of my test.
