What is Android?

Android is an operating system based on the Linux kernel, and designed primarily for touchscreen mobile devices such as smartphones and tablet computers

Open Handset Alliance was formed headed by Google which is composed of companies like Intel, T-Mobile, Spring Nextel and more.

Architecture

Linux Kernel

Native Libraries

The next level up is the native libraries. It Contain libraries for Surface manager, SQLite etc.

Android Runtime

This is in blue, meaning that it's written in the Java programming

The DVM runs something called dex files, D-E-X and these are byte codes that are the results of converting at build time. Class and JAR Files.

Application Framework

This is all written in a Java programming language and the application framework is the toolkit that all applications use.

Application

And the final layer on top is Applications.

This is where all the applications get written.

Advantages

Android is open, because it is Linux based open source so it can be developed by anyone.

It is very user-friendly

Easy in terms of notification: the operating system is able to inform you of a new SMS, Email etc.

Limitations

Wasteful Batteries, This is because the OS is a lot of "process" in the background causing the battery quickly drains.

Many Android phones are not as smooth or fast in operation as the iPhone.

The open platform also means that not every app will work on every Android phone.

Applications

Android phones has many applications in our day-to-day life such as:-

Applications Like m-indicator
