Using images designed for different operating systems, especially desktop-based, is not a good idea. Foreign icons will look weird at best, or will make your Android apps hardly recognizable at worst.Producing Tab and Menu Icons for Android Apps Description: When developing Android apps or designing graphics for Android apps, it is essential to follow srict guidelines. Using icons designed for different operating 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 strict guidelines available in reference to Android icons. Different design guidelines are available for tab icons and menu images. ![]() Tab icons are drawn in individual tabs in tabbed UI. Tab icons should be provided in two different states: unselected and selected. It is recommended that tab icons are designed as simple, flat shapes as opposed to icons shown in 3D or isometric projection. Android OS and Android apps are used on a multitude of different platforms using a wide range of hardware. In connection to icon graphics, those platforms can have different display sizes, screen resolutions, pixel dimensions and density. To accommodate the variety of displays, Android developers should provide 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 resolutions are defined as 24x24, 32x32, and 48x48 pixels. Inner dimensions should not exceed 22x22, 28x28, and 42x42 pixels respectively. By including all three standard resolutions, developers can ensure that their apps will display properly on a wide range of devices running the Android OS. Menu icons are used in the "options" menu, and are shown to users when they press the Menu button. Similar to tab icons, menu icons should be flat, grayscale images. Just as tab icons, developers cannot use 3D or isometric projections. Screen sizes for menu icons are described in a slightly more complex way compared to tab icons. Instead of two resolutions described for tab icons (inner shape and boundary box), the inner shape of menu icons can be smaller or larger depending on their shape. If a menu icon is square-shaped, its size should be smaller than for icons shaped otherwise. The reason for specifying two different size limits is to establish a consistent visual size across the two icon types. The outer dimensions for ldpi, mdpi and hdpi icons are described 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, mdpi icons should fit 30x30 and 32x32 pixel boxes, while high-definition images should fit into 44x44 and 48x48 pixel rectangles respectively. Instead of drawing your own icons conforming to these guidelines, Android developers have an option of obtaining stock graphics from professional designers. As an example, Android Tab Icons by Aha-Soft offer 112 unique tab graphics in selected and unselected states and all three standard sizes. If an additional size is needed, developers can produce icons at any size by accessing scalable vector sources.
