Making Standard Tab and Menu Icons for Android
When developing Android apps or designing graphics for mobile apps, it is essential to conform to certain guidelines. Using graphics designed for different systems, especially desktop-based, is generally not a good idea. Foreign graphics will look out of place at best, or will render your Android apps hardly recognizable at worst.Designing Tab and Menu Icons for Android Description: When developing mobile apps or drawing graphics for Android apps, it is essential to follow certain guidelines. Re-using icons made for different systems, especially desktop-based, is generally not a good idea. Foreign images will look weird at best, or will render your Android apps appear hardly recognizable at worst. Body: There exist precise guidelines published in reference to Android icons. Different design guidelines are available for tab icons and menu icons.
Tab icons are drawn in individual tabs in tabbed interface. Tab icons must be provided in two different states: unselected and selected. It is recommended that tab icons are designed as simple, flat shapes as opposed to images shown in 3D or isometric projection.
Android OS and Android apps can run on a wide range of different platforms using a wide range of hardware. In connection to icon graphics, those devices can have different display sizes, display resolutions, pixel dimensions and density. To accommodate the variety of screens, Android developers should supply all tab icons used in their apps in at least three resolutions to be drawn on low, medium, and high density screens. Resolution-wise, the outer boundaries for the three sizes are defined as 24x24, 32x32, and 48x48 pixels. Inner dimensions should not exceed 22x22, 28x28, and 42x42 pixels respectively. By providing all three standard resolutions, designers can ensure that their apps will be shown properly on a variety of devices running the Android OS.
Menu icons are used in the "options" menu, and are displayed to users when they press the Menu button. Similar to tab icons, menu icons should be flat, greyscale images. Like tab icons, developers cannot use 3D or isometric projections.
Pixel resolutions for menu icons are defined in a slightly more complex way as opposed to to tab icons. Instead of two resolutions defined for tab icons (inner shape and boundary box), the inner shape of menu icons can be smaller or bigger depending on their shape. If a menu icon is square-shaped, its resolution should be smaller than for icons shaped otherwise. The reason for having two different sizes is to establish a consistent visual weight across the two icon types.
The outer dimensions for low, medium, and high resolution icons are described as 36x36, 48x48, and 72x72 pixels respectively. Inner shapes for square, low-definition icons is 22x22 pixels, while non-square icons should fit into a boundary box sized 24x24 dots. Similarly, medium-definition icons should fit 30x30 and 32x32 pixel boundaries, while high-definition images should fit into 44x44 and 48x48 pixel boxes respectively.
Instead of drawing your own graphics matching these guidelines, Android developers have an option of ordering ready-made graphics from professional designers. For example, Android Tab Icons by Aha-Soft include 112 unique tab images in both states and all three standard resolutions. Should additional resolutions be required, developers can produce icons at any resolution by opening scalable vector sources.
