That is to say, as long as the key driver processing-related logic is transferred to the Android platform, only the basic communication functions are retained in linuxkernel, even if some of the Code is open source, there will be no loss for the manufacturer. Google chose to do this and specifically modified

However, if the Phar archive does not use the native Phar-based archive format, it does not need to use the Phar extension to load the archive, but it is required to use the Phar archive in ZIP or TAR format. Next, you need to define the file stub (stub), which is the first code called when loading the Phar file. Phar file stubs The file

Is where Hal is located in the Android system:As you can see from this diagram, Hal isolates the kernel from the framework so that the upper layer can be developed without relying on kernel and driver implementations. In Android source code, HAL is roughly in the following locations: libhardware_legacy/-The old schema, taking the mode of the link library module. Libhardware/-New architecture, tuning to the concept of HAL
