Implemented HIDL (HAL Interface Definition Language) interface and new binderized HAL (Hardware Abstraction Layer) interface, updated OEM's respective AIDL interface and Android service (user-controlled power and connectivity parameters of the vehicle-mounted device), removed redundant JNI layer, replacing it with new HIDL to provide service to HAL communication, added SELinux policies to

HALs expressed in HAL interface definition language (HIDL) or Android interface definition language Passthrough HALs. A HIDL-wrapped conventional or legacy HAL . These HALs wrap existing HALs and can serve the HAL in A minimal but complete binderized HAL service implementation for Android Q. I need to write a HAL to access sysfs entry from android APP but the thing is, the whole processing should not take more that 2 ms. What can be the best way to define the HAL or in simple language the fastest HAL. I have implemented a binderized HAL and it is taking around 17 ms.

Through such a Framework / HAL separation design and interface consistency guarantee, the Android system after the 8.0 version can be upgraded directly when the platform is upgraded without considering the HAL layer changes, thereby shortening the system for the user to get the system.

Only 0.3 (3) and below are supported by this HAL." So it seems my particular device does not have the old 0.3 gralloc, it has gralloc 1.0. This leads to some questions: 1，Binderized HALs，从名字上应该是指Binder化的HAL，对Android 比较熟悉的同学应该对binder这个东西很熟悉，我们是不是可以大胆猜猜下Android 8.0里的HAL是不是都是binder化了？ Binderized.
