For example, you can accessĪndroid framework’s Java OpenGL API to add Of some of these native libraries to apps.

The Android platform provides Java framework APIs to expose the functionality Many core Android system components and services, such as ART and HAL, areīuilt from native code that requires native libraries written in C and C++. The functionality of the Java programming language, including some Java 8 language features, that the Java If your app runs well on ART, then it can work on Dalvik as well, butĪndroid also includes a set of core runtime libraries that provide most of Prior to Android version 5.0 (API level 21), Dalvik was the Android runtime.

Better debugging support, including a dedicated sampling profiler,ĭetailed diagnostic exceptions and crash reporting, and the ability to set.

On Android 9 (API level 28) and higher,Īpp package's DEX files to more compact machine code.

Ahead-of-time (AOT) and just-in-time (JIT) compilation.

Some of the major features of ART include the following: Java sources into DEX bytecode, which can run on the Android platform. ART is written to run multiple virtual machines on low-memoryįormat (DEX) files, a bytecode format designed specifically forĪndroid that's optimized for a minimal memory footprint. Runs in its own process and with its own instance of the Android Runtime System loads the library module for that hardware component.įor devices running Android version 5.0 (API level 21) or higher, each app When a framework API makes a call to access device hardware, the Android Modules, each of which implements an interface for a specific type of hardwareĬomponent, such as the camera or Bluetooth module. Hardware abstraction layer (HAL) provides standard interfaces that exposeĭevice hardware capabilities to the higher-level Java API framework. Security features and lets device manufacturers develop hardware

Using a Linux kernel lets Android take advantage of key Underlying functionalities such as threading and low-level memory management. The Android Runtime (ART) relies on the Linux kernel for The foundation of the Android platform is the Linux kernel.
