This guide will first discuss how to use fonts as an Android resource, and then move on to discuss how to download fonts at runtime. For example, the following snippet demonstrates how to display a font in a TextView: For example, this XML snippet declares a new font family resource that will work in API level 14 and higher: Īs long as fonts are provided to an Android application in a proper way, they can be applied to a UI widget by setting the fontFamily attribute. If only the android: namespace is used, then the fonts will not be displayed devices running API level 25 or less. When targeting the older API levels, it is necessary to declare the app XML namespace and to name the various font attributes using the android: namespace and the app: namespace. The Android Support Library v26 will backport support for fonts to API level 26. This allows developers to specify certain attributes of the font, such as it's weight, and Android will automatically select the appropriate font from the font family. Similar fonts (or a font that may have several different styles) may be grouped into font families. This font can be shared between multiple applications. If necessary, the font will be downloaded and cached on the device. The font provider checks if the font is already on the device. Download the fonts – Android also supports downloading a font from a font provider.Package the font as an Android resource – this ensures that the font is always available to the application, but will increase the size of the APK.
The Android Support Library 26 NuGet will backport the new font API's to those apps that target API level 14 or higher.Īfter targeting API 26 or installing the Android Support Library v26, there are two ways to use fonts in an Android application: Beginning with API level 26, the Android SDK allows fonts to be treated as resources, just like a layouts or drawables.
