Hope it works o.k. for you too like this.
//1) clean project, "trash" icon.
//2) remove all types of icons IN project folder.
//3) IF you want the white frame, put there an "icon.png"
// IF you don't want it put there the same image,
// with name "androidicon.png"
// The image must be PNG format, 72x72.
// [PNG is great FOR transparency AND other things]
//4) Rebuild FOR android, AND voila.
If trouble or doubt, try building the project twice.
