Analysis of Android HAL layer framework

The previous analysis shows how the android HAL layer searches for the dynamic shared library of hardware modules. In fact, it is to find the shared library modueid under the two paths of "system/lib/hw /" or "/ vendor/lib/hw /" variant. After so, load the library by calling the load function. Now let's enter the load funct ...
