Making Standard Tab and Menu Icons for Android
When developing Android apps or drawing graphics for mobile apps, it is essential to follow certain guidelines. Using images made for different systems, especially desktop-based, is not a good idea. Foreign images will look weird at best, or will make your Android apps hardly recognizable at worst.Making Tab and Menu Icons for Android Apps Description: When designing mobile apps or designing graphics for mobile apps, one must conform to srict guidelines. Using icons designed for different systems, especially desktop-based, is generally not a good idea. Foreign icons will look weird at best, or will render your Android apps hardly recognizable at worst. Body: There exist precise guidelines available in reference to Android icons. Different design guidelines are available for tab icons and menu graphics.
Tab icons are drawn in individual tabs in tabbed interface. Tab icons should be supplied in two different states: selected and unselected. It is recommended that tab icons are drawn as simple, flat shapes as opposed to icons shown in 3D or isometric projection.
Android OS and Android apps are used on a variety of hardware platforms employing a wide range of hardware. In reference to icon images, those platforms can have different display sizes, screen 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 supplying all three standard resolutions, developers can ensure that their apps will be shown properly on a wide range of platforms running the Android OS.
Menu icons are used in the "options" menu, and are shown to the user when they press the Menu button. Similar to tab icons, menu icons are specified as flat, greyscale images. Just as tab icons, developers should not use 3D or isometric projections.
Pixel resolutions for menu icons are described in a slightly more complex way compared to tab icons. Instead of just two resolutions defined for tab graphics (inner shape and boundary box), the inner shape of menu icons can be smaller or larger depending on whether they are square-shaped or not. If a menu icon is square-shaped, its size should be smaller than for icons shaped otherwise. The reason for having two different size limits is to establish a consistent visual weight across the two icon types.
The outer dimensions for ldpi, mdpi and hdpi icons are defined as 36x36, 48x48, and 72x72 pixels respectively. Inner shapes for square, low-definition icons should be 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 boxes, while high-definition images should fit into 44x44 and 48x48 pixel boundaries respectively.
Instead of drawing your own images matching these guidelines, Android developers have an option of obtaining ready-made images from professional designers. As an example, Android Tab Icons by Aha-Soft offer 112 unique tab icons in selected and unselected states and all standard sizes. Should additional resolutions be required, developers can render icons at any resolution by opening scalable vector sources.
