When using single icon as application icon in config.xml this way "<icon src ="icon.png" platform="android" />" cordova should use basic drawable folder, because doesn't matter of resolution, PPI, etc., so doesn't matter of device and for this purpose there are "drawable" folder. Not use drawable-hdpi, drawable-ldpi and so on. Icons in these folders in this situation should be deleted.
It's really not neccessary to have 5 not similar, but exactly same icon files, when we can have only 1 icon file.
