Question

I refer to the documentation at http://developer.android.com/guide/practices/ui_guidelines/icon_design.html#icon-sets

Hence, I plan to have the following directory structures.

res/
    drawable/   
        icon.png (? x ? px)
    drawable-ldpi/  
        icon.png (36x36 px)
    drawable-mdpi/  
        icon.png (48x48 px)
    drawable-hdpi/  
        icon.png (72x72 px)

However, I cannot find any documentation, to mention the size of default launcher icon size.

May I know what should be the default launcher icon size?

I don’t think you need to supply an image in the drawable/ directory if you have populated drawable-ldpi/ drawable-mdpi/ and drawable-hdpi/ with launcher icons.
