Introduction
In this blog, we will discuss Android OS Architecture. The Android operating system comprises a stack of software components separated into five divisions and four main layers. The Android operating system’s components are
- Linux kernel
- Libraries
- Android Run time
- Application Framework
- Applications
With Android training in Mumbai at FITA Academy, you may learn the essential abilities for working with various Android platforms and programming.
Linux kernel
Linux kernel is the operating system’s foundational component for Android. Google made a few architectural changes to the Linux 2.6 Kernel before layering them on top of Android. The Linux kernel provides basic system features like process, memory, and device management for cameras, keypads, displays, etc. Also, it offers a variety of device drivers that make it simple to connect the Android to auxiliary gear.
Libraries
A further layer called libraries is present on top of the Linux kernel. It offers several libraries that are helpful for the Android operating system’s smooth operation. Java libraries explicitly created for the Android operating system are called libraries. Giving students a base in coding so they may make unique apps is the aim of Android Training in Hyderabad.
Android Runtime
It is set in the second layer from the bottom of the android architecture and is the third component. It provides the Dalvik Virtual Machine, the most crucial Android part. The sole distinction between Dalvik Virtual Machine and Java Virtual Machine (JVM) is that the former was created and optimized for Android. Dalvik Virtual Machine enables each Android app to run as a separate process by utilizing fundamental Linux features like memory usage and multi-threading.

Application framework
It is part of the Android operating system stack’s fourth layer. The application framework and Android applications communicate directly. The application framework controls the fundamental operations of an Android smartphone, including resource management and voice call control. In the form of Java classes, the application Framework layer offers various higher-level services to applications. Application developers may use these services in their creations.
Conclusion
So far, we have enhanced Android OS Architecture. Android apps are necessary across the board for all uses. A great Android developer can create an app that will help millions. Because they make our lives easier, we utilize applications daily.
