Learn about the roadmap for establishing Android as a first-class platform for GTK and discover practical guidance for developing Android applications using the GTK framework.

Android and iOS are not supported by GTK, but there is some early experimental support for the Librem mobile devices manufactured by the Purism company. As GTK is compact and has a modular design, it can also be used on devices with restricted resources like the Raspberry Pi family.
