Android Studio includes a tool called Image Asset Studio that helps you generate your own app icons from material icons , custom images, and text strings. It generates a set of icons at the appropriate resolution for each pixel density that your app supports. At runtime, Android uses the appropriate resource based on the screen density of the device your app is running on.
Image Asset Studio helps you create various types of icons at different densities and shows you exactly where they'll be placed in your project.
The following sections describe the icon types that you can create and the image and text inputs that you can use.
A launcher icon is a graphic that represents your app to users. It can: Appear in the list of apps installed on a device and on the Home screen. Represent shortcuts into your app for example, a contact shortcut icon that opens detail information for a contact. Be used by launcher apps. Help users find your app on Google Play. Adaptive launcher icons can display as a variety of shapes across different device models and are available in Android 8.
Android Studio 3. Image Asset Studio generates previews of an adaptive icon in circle, squircle, rounded square, and square shapes, as well as a full bleed preview of the icon. A legacy launcher icon is a graphic that represents your app on a device's home screen and in the launcher window. Legacy launcher icons are intended for use on devices running Android 7. It also creates a x pixel image that's appropriate for the Google Play store. We recommend that you use the material design style for launcher icons, even if you support older Android versions.
Action bar icons are graphical elements placed in the action bar and that represent individual action items. Tab icons are graphical elements used to represent individual tabs in a multi-tab interface. Each tab icon has two states: unselected and selected. We recommend that you use the material design style for action bar and tab icons, even if you support older Android versions. Use appcompat and other support libraries to deliver your material design UI to older platform versions.
Vector drawables are appropriate for simple icons and can reduce the size of your app. A notification is a message that you can display to the user outside of the normal UI of your app. If your app supports Android 2. Later Android versions use the white icon that Image Asset Studio generates.
For more information, see Material Icons. You can import your own images and adjust them for the icon type. Image Asset Studio lets you type a text string in a variety of fonts, and places it on an icon. It converts the text-based icon into PNG files for different densities. You can use the fonts that are installed on your computer. Note: If your app supports versions no higher than Android 7.

File-based resource names must contain only lowercase a-z, , or underscore. The developer has to know the filename during development, and not runtime. So, in assets, one can read the filename during runtime, list them, and use them dynamically.
