HALs on Android are shared libraries with well defined names for entry points. Like all shared libraries, they can be chained. Chaining HALs can allow reuse or debugging of existing binary only HALs. Many Android systems are based customization of reference designs or even repurposing existing off the shelf designs. Chaining HALs provide addition customization options to existing Android systems. Chaining HALs can provide an alteranative vendor delays and hesitation with customizing or fixing binary only HALs.. Customization on a HAL level can have added benefits such as keeping existing security models intact futher up the Android stack.
