Android is the leading open-source operating system that is based on Linux kernel and was initially designed for touch screen devices. Developed in the year 2003 by Palo Alto, Android was developed by an Open Handset Alliance (OHA).  OHA is an association of 84 companies that includes Google, Samsung, Teleca, eBay, Intel and many more. Later in the year 2005, Google acquired Android and today it is being led and carried out under the name of AOSP (Android Open Source Project). Google is the one that provides all the software updates. Android today has become the world’s leading mobile operating system that covers almost 76.61% of Worldwide Operating System Market and therefore it is important for the developers to become familiar with all the latest updates and working environment of Android operating system. The 6 weeks Android Summer Industrial Training in Noida is the best way to stay up-to-date with the Android environment.

Before understanding Android, we first need to understand the meaning and importance of the term operating system. It is because of operating systems that the device is able to understand the user's request and transfer them to the software of the device. The operating system acts as a mediator between the user and the device’s software system. Now there are many operating systems in the market but the most used and the leading operating system is Android. Since Android is an open source software, every company modifies it according to their own requirements and therefore Google uses AOSP as a base to create its version of Android. Samsung, Huawei, Sony, Lenovo, HTC and LG are some of the manufacturers that use Android in their devices.

Android is a Linux based operating system. A Linux OS is freely distributable; a cross-platform operating system that is based on UNIX and provides the operating system with various benefits, like portability, multi-user, and multitasking. Over the year android has provided the customers with many different updates. The best and unique part of Android's update is its name. Every update gets a code name based on consecutive letters of the alphabet, like Lollipop, KitKat, Marshmallow, Jelly Bean, Gingerbread and the latest being Pie.

Nowadays developers who work on an application for android are the most benefited ones. There are many reasons for any developer to work for Android and mentioned below are just a few of them:

• Leading OS: Obviously, the first point had to be the popularity that Android developers enjoy. It is the world's leading operating system covering more than half of the OS market. Moreover, working for such a big company itself is a big deal.

• Open source: Being open source software freely allows the developers and manufacturers to customize the software according to their requirement and can even distribute it.

• Widespread reach: Today, Android has 2 billion monthly active users that prove it’s a widespread reach.

• Increase in marketing: One of the best parts about developing an application for Android is that there will be millions of users that will be using your application. There will be no marketing cost and yet the application will be marketed around the world with the help of the play store.

• Integration with other apps: Since Google is handling Android; therefore other applications by Google are fully supported by Android.

• Great User Interface

• SQLite is used for storage purpose

• Witten in JAVA: Among many other languages, Java is the most prominent one that is used for writing codes of Android. Since the codes are based on Java programming language, developers can easily understand, learn, create and deploy applications in the Android environment.

There are 5 sections in android architecture:

• Applications
• Application Framework
• Android Runtime
• Libraries

• Linux kernel

This is the arrangement in which android architecture is composed. Now let us look at each and every component of Android architecture.

1. Applications

The first layer is the Application layer where all the installed applications are present. These applications generally involve Contacts, Camera, Alarm, Calendar, Email, Clock, and many more.

2. Application framework

This comes at the second place and integrates with the applications on the device and offers services that make the applications work smoothly. This framework makes changes to the application. Application framework includes:

• Activity Manager
• Resource Manager
• View System
• Notification manager

3. Android Runtime

Dalvik Virtual Machine (DVM) becomes really important during the runtime. DVM is a virtual machine that is specially optimized and designed for Android. DVM allows multiple applications to run effectively on a single device. It even handles low-level functionality that includes threading, security, and memory management.

4. Libraries

Android provides the developers with a set of libraries that includes open graphics library, SQLite database, SSL libraries, web browser engine WebKit, libraries to play and record audio and video, C/C++ based libraries and many more.

5. Linux kernel

As mentioned earlier, Android is based on Linux kernel. Linux Kernel offers separation among the device hardware and helps the hardware to work properly by providing the necessary drivers, like the keypad, camera, display etc. Linux Kernel helps the system to stay secured by increasing safety between the application and the system. It even manages the processing and allocation of the resources. Finally, it offers effective network communication.

This was just a gist about the Android Operating system. There are a lot more components in this software that a developer must know about. Since Android is the leading OS in the market, it, therefore, becomes an unsaid rule for the prospective employees to become familiar with all the aspects of Android. One can learn in detail about this operating system by enrolling themselves with the best 6 weeks Android Summer Industrial Training in Noida.
