Android RuntimeĮach android app based on Android version 5.0 (API level 21) or higher, runs in its own process and with its own instance of the Android Runtime (ART). So, when you make a call to access device hardware using Java API, the Android system loads the library module for that hardware component. The Android HAL contains multiple library modules for a specific type of hardware components, such as the camera or bluetooth module. The hardware abstraction layer (HAL) allows the Android application/framework to communicate with the hardware specific device drivers with the help of higher-level Java API. The Android Runtime (ART) relies on the Linux kernel for underlying functionalities such as threading and low-level memory management etc. The Linux kernel provides a multitasking execution environment which allows multiple processes to execute concurrently.
