What are the 7 basic components of Android?

Posted on May 24, 2022March 3, 2023

Android is the world’s most popular mobile operating system, powering billions of devices around the globe. As an open source platform, Android is designed to be highly customizable, allowing developers to craft unique user experiences. To do this, Android relies on a set of seven core components, each of which plays a significant role in the functioning of the system. In this article, we’ll take a closer look at these components and explore how they interact.

The first component is the Application Framework. This is the core of the Android operating system and provides the basic building blocks necessary for constructing Android apps, such as user interfaces, content providers, resource managers, and other key features. It also provides an API for accessing hardware components such as the camera, GPS, network, and Bluetooth.

The second component is the Libraries. These libraries provide access to common tasks, such as networking, graphics, and media playback. These libraries are written in native code and are optimized for performance and power efficiency.

The third component is the Android Runtime (ART). This is the core part of the Android operating system that allows applications to run. It includes a set of core libraries, a virtual machine, and a set of debugging and profiling tools. ART is more efficient than other virtual machines and allows applications to launch quickly and run smoothly.

The fourth component is System Services. These system services provide access to the hardware and services on the device, such as location, sensors, and Wi-Fi. These services are written in C/C++ and are optimized for performance and power consumption.

The fifth component is the Dalvik Virtual Machine (DVM). This is an Android-specific implementation of the Java Virtual Machine (JVM) and allows applications written in Java to run on the Android platform.

The sixth component is Native Libraries. These libraries are written in the C/C++ language and provide access to low-level hardware features. Examples of native libraries include the Open GL graphics library and the SQLite database library.

Finally, the seventh component is the Android Kernel. This is the core of the operating system and provides the interface between the hardware and the other software components. It includes device drivers for accessing hardware components such as the camera, GPS, network, and Bluetooth.

To sum up, Android is a powerful and versatile operating system, and its success is largely due to its seven basic components. Each component plays an important role in the system’s functioning and allows developers to create unique and powerful user experiences. By understanding how these components work together, developers can create innovative and powerful apps for the Android platform.
