Yet another important change for the Nokia Asha UI is icon style. Let’s start with the launcher icons!
The launcher icon you need to create and pack with your MIDlet (or Web app, for that matter) is 50×50 pixel square shaped icon. This icon will show on the activity screen. However, when you look at your icon on the Home screen you will notice that your icon has in some mystical way changed to the surround shape. This is because the phone trims the icon to the correct shape. You don’t need to worry about that. In any other aspect, than you should try out how your icon will look when trimmed.
Luckily, we provide the perfect tool for you for checking how the cutting will affect your icon. The Nokia Asha Icon toolkit contains launcher icon templates for you to easily create your launcher icon in correct size and shape, and also let’s you preview the surround version. The icon templates support Adobe Illustrator, Adobe Photoshop, and Inkscape.
Now, let’s briefly compare CategoryBar icons for Full touch and Nokia Asha UI. As the background color has changed from dark to light, we also need to take care of the CategoryBar icons. The ones you have for Full touch won’t work anymore; the contrast between the icon and the CategoryBar background is not high enough. Luckily, the Nokia icon toolkit also has a good number of ready-to-use CategoryBar icons for you to use if the default icons won’t cover your needs.
Don’t forget the UX checklist, either!
