several reasons for HAL: 1. Not all hardware devices have standard Linux kernel interfaces. 2. the kernel driver is copyrighted by GPL. Some device manufacturers do not disclose hardware drivers for any reason, so they use Hal to bypass GPL. 3. Android has some special requirements for some hardware. In the Display Section, the Hal implementation code is in copybit. C. The application can directly operate
