Re-using images made for other systems, especially desktop-based, is generally not a good idea.

Using icons made for different systems, especially desktop-based, is 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 strict 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 must be provided in two different states: selected and unselected. It is required that tab icons are designed as simple, flat shapes as opposed to images drawn in 3D or isometric projection. Android OS and Android apps can run on a multitude of hardware platforms using a wide range of hardware. In reference to icon images, those devices can have different screen sizes, display resolutions, pixel dimensions and density. To accommodate the variety 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. Resolution-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 including 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 shown to users 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 described in a slightly more complex 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 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 specifying two different sizes is to establish a consistent visual size 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 is 22x22 pixels, while non-square icons should fit into a boundary box sized 24x24 pixels. 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 images matching these guidelines, Android developers have an option of obtaining ready-made icons from professional designers. As an example, Android Tab Icons by Aha-Soft offer 112 unique tab graphics in both states and all three standard sizes. Should additional resolutions be required, developers can render graphics at any size by opening scalable vector sources.
