NEW QUESTION 20
Select correct statements about Hardware Abstraction Layer (HAL). (Choose two.)

• A. The HAL consists of multiple library modules, each of which implements an interface for a specific type of hardware component, such as the camera or bluetooth module. When a framework API makes a call to access device hardware, the Android system loads the library module for that hardware component.
• B. Using a HAL, not using a Linux kernel, allows Android to take advantage of key security features and allows device manufacturers to develop hardware drivers for a well-known kernel.
• C. The HAL function both as apps for users and to provide key capabilities that developers can access from their own app. For example, if your app would like to deliver an SMS message, you don't need to build that functionality yourself - you can instead invoke whichever SMS app is already installed to deliver a message to the recipient you specify
• D. The HAL provides standard interfaces that expose device hardware capabilities to the higher-level Java API framework.

Answer: A,D
