A Launcher icon is a graphic that represents your application on the device's Home screen and in the Launcher window.
The user opens the Launcher by touching the icon at the bottom of the Home screen. The Launcher opens and exposes the icons for all of the installed applications. The user selects an application and opens it by touching the Launcher icon or by means of any hardware navigation controls available, such as a trackball or d-pad.
As described in Providing Density-Specific Icon Sets, you should create separate icons for low-, medium-, and high-density screens. This ensures that your icons will display properly across the range of devices on which your application can be installed. See Tips for Designers for suggestions on how to work with multiple sets of icons.
If you are publishing your application on Android Market, you will also need to provide a 512x512 pixel, high-resolution application icon in the developer console at upload-time. This icon will be used in various locations in Android Market and does not replace your launcher icon.
For tips and recommendations on creating high-resolution launcher icons that can easily be scaled up to 512x512, see Tips for Designers.
For information and specifications about high-resolution application icons in Android Market, see the following article:
Starting with Android 2.0, launcher icons should be front-facing, instead of at a three-quarter perspective. The following guidelines describe how to design launcher icons for Android 2.0 (API Level 5) and later.
The launcher icons that you create should follow the general style principles below. The guidelines aren't meant to restrict what you can do with your icons, but rather they are meant to emphasize the common approaches that your icons can share with others on the device. Figure 1, at right, provides examples.
Clean and contemporary:
Simple and iconic:
Tactile and textured:
Forward-facing and top-lit:
Note: Android applies separate text labels using the application name when displaying launcher icons, so you should avoid embedding text in your icon and instead focus on designing a distinct and memorable icon.
Launcher icons should use a variety of shapes and forms that are scaled and positioned inside the asset to create consistent visual weight with other icons.
Figure 2 illustrates various ways of positioning the icon inside the asset. You should size the icons smaller than the actual bounds of the asset to create a consistent visual weight and to allow for shadows. If your icon is square or nearly square, it should be scaled even smaller.
In order to indicate the recommended size for the icon, each example in Figure 2 includes three different guide rectangles:
Launcher icons should make use of tactile, top-lit, textured materials. Even if your icon is just a simple shape, you should try to render in a way that makes it appear to be sculpted from some real-world material.
Android launcher icons usually consist of a smaller shape within a larger base shape and combine one neutral and one primary color. Icons may use a combination of neutral colors but should maintain a fairly high level of contrast. Icons should not use more than one primary color per icon, if possible.
Launcher icons should use a limited color palette that includes a range of neutral and primary colors. The icons should not be over-saturated.
The recommended color palette to use for Launcher icons is shown in Figure 3. You can use elements of the palette for both the base color and the highlight color. You can use the colors of the palette in conjunction with a white-to-black vertical linear gradient overlay. This creates the impression that the icon is lit from above and keeps the color less saturated.
When you combine the materials in Figure 4 with a color highlight from the
recommended palette above, you can create materials combinations such as those
shown in Figure 5. To get you started, the
Icon Templates Pack
includes a Photoshop file (
that provides all of the default materials, colors, and gradients.
Launcher icons are flat and the perspective is straight-on, rather than at an angle. A drop shadow is used to create a sense of depth. Launcher icons can use varying textures and lighting effects, but must be lit directly from above (straight down).
In order to maintain consistency, all launcher icons should use the same drop shadow effect, as shown in Figure 6.
Below are some "do and don't" examples to consider when creating icons for your application.

The following guidelines describe how to design launcher icons for Android 1.6 (API Level 4) and earlier. Launcher icons for Android 1.6 and below are simplified 3D icons with a fixed perspective. The required perspective is shown in Figure 8.
Launcher icons are simplified 3D icons using light and shadows for definition. A light source is placed slightly to the left in front of the icon, and therefore the shadow expands to the right and back.
