Producing Standard Tab and Menu Icons for Android
When designing Android apps or designing graphics for mobile apps, one must conform to srict guidelines. Using images made for other systems, especially desktop-based, is generally not a good idea. Foreign images will look out of place at best, or will render your Android apps appear hardly recognizable at worst.Making Standard Tab and Menu Icons for Android Description: When designing mobile apps or designing graphics for Android apps, one must follow srict guidelines. Re-using images designed for different systems, especially desktop-based, is generally not a good idea. Foreign icons will look out of place at best, or will render your Android apps appear hardly recognizable at worst. Body: There are precise guidelines published in reference to Android icons. Different design guidelines are available for tab icons and menu graphics.
Tab icons represent individual tabs in tabbed UI. Tab icons must be provided in two different states: unselected and selected. It is required that tab icons are created as simple, flat shapes as opposed to images shown in 3D or isometric projection.
Android OS and Android apps are used on a variety of different platforms employing a wide range of hardware. In connection to icon images, those platforms can have different display sizes, screen resolutions, pixel density and dimensions. 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 displayed on low, medium, and high density displays. Pixel-wise, the outer boundaries for the three resolutions are defined as 24x24, 32x32, and 48x48 pixels. The size of the shape itself should not exceed 22x22, 28x28, and 42x42 pixels respectively. By providing all three standard sizes, developers 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 users when they press the Menu button. Similar to tab icons, menu icons are specified as flat, grayscale images. Like tab icons, developers cannot use 3D or isometric projections.
Pixel sizes for menu icons are defined in a slightly more comprehensive way as opposed to to tab icons. Instead of just two resolutions described 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 dimensions 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 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 boxes respectively.
Instead of designing your own graphics matching these guidelines, Android developers have an option of ordering 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 three standard resolutions. If an additional size is needed, developers can render graphics at any size by opening scalable vector sources.
