I'm trying to put the finishing touches on my app design. The launcher icon I have been using is properly scaled for mdpi,hdpi,x,xx but still seems to appear of lower resolution. I've tried a few other things, deleting all lower resolution versions and using a ridiculously oversized version. The logo I'm sizing down is very high resolution to start with. I am doing this all in photoshop. I'm checking the icon appearance using my phone and not an emulator and just to be certain, I've been deleting the app so a new icon is loaded each time.
Use other icons and see what makes it happened.
No need to use a very high resolution.
