I think it works with PNG not PSD, but I may be wrong. Anyway, if your splash and icons were correctly generated under resources/android that shouldn’t be the problem and I may be wrong.
When you have ran the command “ionic resources”, not only the splash and icon should have been generated, your config.xml should had been modified too (config.xml gonna tell cordova which splash and icons should be use when you build your app)
Could you double check that the urls to the splash and icon specified in config.xml for android are actually the same as the real data you’ve got under your resources/android?
If it’s ok, have you build “ionic build android” your app again (I know silly question ;))
Maybe you could also try following commands, sometimes work
ionic resources android --force
But well was the same for me…wasn’t able to set up icon and splash in 5 minutes, took a little bit of time too
