Making Tab and Menu Icons for Android Apps
When designing Android apps or designing graphics for Android apps, one must follow srict guidelines. Re-using graphics designed for other operating systems, especially desktop-based, is not a good idea. Foreign icons will look weird at best, or will render your Android apps appear hardly recognizable at worst.Designing Tab and Menu Icons for Android Description: When designing Android apps or drawing graphics for mobile apps, one must conform to certain guidelines. Using graphics designed for different systems, especially desktop-based, is generally not a good idea. Foreign images will look out of place at best, or will make 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 represent individual tabs in tabbed interface. Tab icons must be provided in two different states: selected and unselected. It is recommended that tab icons are created as simple, flat shapes as opposed to icons shown in 3D or isometric projection.
Android OS and Android apps can run on a variety of hardware platforms employing a wide range of hardware. In reference to icon graphics, those devices can have different display sizes, display resolutions, pixel dimensions and density. To accommodate the wide range of screens, Android developers must provide all tab icons used in their apps in at least three resolutions to be shown on low, medium, and high density displays. 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 sizes, designers can ensure that their apps will be shown properly on a variety of platforms running the Android OS.
Menu icons are drawn in the "options" menu, and are displayed to the user when they press the Menu button. Similar to tab icons, menu icons should be flat, grayscale images. Like tab icons, developers cannot use 3D or isometric projections.
Pixel resolutions for menu icons are defined in a slightly more comprehensive way as opposed to to tab icons. Instead of just two sizes described for tab icons (inner shape and boundary box), the inner shape of menu icons can be smaller or bigger depending on whether they are square-shaped or not. If a menu icon is square-shaped, its resolution should be smaller than for icons with different shapes. 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 defined 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, mdpi icons should fit 30x30 and 32x32 pixel boundaries, while high-definition images should fit into 44x44 and 48x48 pixel rectangles respectively.
Instead of designing your own icons conforming to these guidelines, Android developers have an option of getting ready-made icons from professional designers. For example, Android Tab Icons by Aha-Soft include 112 unique tab icons in selected and unselected states and all standard sizes. Should additional resolutions be required, developers can produce graphics at any resolution by opening scalable vector sources.
