WHAT IS ANDROID

                                             

                           
 Introduction 

As of late, mobile application development has been developing quickly, both regarding incomes and employment scopes made by that field. This article is all about the concise outline and diagram of relentless Android, the most rising mobile application development stage now a days.

The article shows an unmistakable looking at picture why engineers should think about creating Android over other mobile stages. Additionally, an abnormal state review of various layers of Android engineering stack and parts of fundamental structure squares of an Android application are talked about here. In the event that you are an Android excited, as to play with code and would love to make astonishing applications with it, how about we plunge into the profound Android sea!

History of Android

We as a whole know today, Google possesses Android, isn't that so? Be that as it may, what a number of us know the back history of Android? Indeed, there was an energizing history behind the present Google featured Android OS. Android Inc. was established in October 2003 by Andy Rubin, Rich Miner, Nick Sears and Chris White. What's more, do know the interesting part? Android was Andy Rubin's moniker for his attraction of robots. They were endeavouring to fabricate an OS for advanced cameras around then.

All things considered, later history is gigantic. How about we check some key purposes of that history to all the more likely comprehend the situation. Rubin and his group later moved their consideration towards cell phone as of computerized camera's short market openings. Later his companion Steve Perlman syphoned up Rubin's work with $10,000 money.

In 2005, Google purchased Android Inc., later Rubin and his group gave themselves to fabricate a mobile gadget stage fueled by Linux Kernel. In November 5, 2007, Google officially reported the development of Android OS. Android Beta was discharged in that day, this November 5 is Android's birthday.The first business variant, Android 1.0(API dimension 1) was discharged in September 2008 pursued by SDK(Software Development Kit) discharge in the same month. First official codename "Cupcake" (Android 1.5, API level 3) was discharged on April 27,2009. We know the later history pretty much, serially it was(by codename)- Donut(1.6), Éclair(2.0), Froyo(2.2), Gingerbread(2.3), Honeycomb(3.0), Ice Cream Sandwich(4.0), Jelly Bean(4.1), and now the latest KitKat(4.4).

Pause, most likely one thing we have to know more. Shouldn't something be said about the popular adorable logo of Android? Do any of you even consider it or know anything where it originates from? All things considered, in short, it originated from the celebrated Star War robot R2-D2. The current logo was structured by Irina Block however Dan Morrill planned some before forms of that logo.

Prior to Beginning

This article is only the start of up and coming Android development instructional exercise arrangement following this one. So for development or you can peruse for coding an android application, you need great knowledge on JAVA and OOP, just to feel good with the Android stage. In the event that you believe you don't have enough knowledge no issue, set aside some effort to learn JAVA and OOP.

Welcome to Android

Lastly, welcome you to the glamorous Android World. Do you feel eager to have an incredible begin? How about we burrow inside.

What is Android?

All things considered, theoretically, you can mean a robot with human appearances yet technically it is an open-source working framework dependent on Linux part, presently claimed and kept up by Google, was constructed chiefly for cell phone and tablet gadgets. Remember one point alongside it, right now Android is the world's most mainstream mobile OS. Do you see the pattern of cell phone applications all over the globe? Indeed, you can consider Android is that change, who is driving from the front.

Why Android?

Yes, at this stage presumably you are figuring why you ought to create applications in Android, what's the advantage over other settled mobile OS in the market. Certainly, you are a decent scholar!

How about we think carefully

- Android is an open-source OS, so it is free and open to utilizing.

- You should think about your app's worldwide circulation, isn't that so? There are a number of parts of the reality where another mobile OS is in no match with Android's popularity(Consider China and other Asian nations, where 90% of the cell phone's OS is Android).

- Android covers a wide scope of hardware made by various producers. So developers certainly have their favourable circumstances to utilize those hardware highlights.

- Statistics of 2014 stated, Android has 80.2% cell phone market share and 75% mobile application developers are creating apps for the Android stage. So do you feel the heaviness of the market of your next-app?

- You can utilize your everything advancement apparatuses for nothing and can create in your home with your pc(no matter you have a Macintosh, windows or Linux).

- On Startup what prerequisites do you expect while distributing your app? A sensible measure of designer enrollment charge, wide app dissemination channel, greater network and so forth.

                                           

- Android will give them all. Google

Play(Android app's greatest market) engineer

enrollment just requires $25 to open record,

unreasonably simple for apprentices contrasting and other

mobile stage's market.

- User input is a significant point on the off chance that

to increment app quality. Android has a major.

gathering of people under its rooftop, you will get extremely brisk

reactions from them in the wake of distributing your app.

- This legitimately drives you to improve your app execution.

- More or less developers or software engineers know java and has an idea on OOP. So it's far simpler for them to get habituated in an android stage in most brief possible time instead of other mobile stages.

- Android has a major designer network as well. On the off chance that you face an issue while composing your code, you will get prompt reaction from them which is extremely useful for a beginner.

- Android gadgets are modest contrasting and other mobile stages. As a designer, you will regularly need to test your app in a genuine gadget before distributing it to a market. Around then, without a doubt, you will feel great with Android at its modest cost.

Review of Android

Android Architecture Stack

You can consider Android OS as a product stack of various layers. Each layer is a gathering of program parts and gives various administrations to the layer simply above it.

Android engineering stack composed of 4 primary layers :

- Linux Kernel

- Libraries alongside Android Runtime

- Application Framework and

- Applications

- Linux Kernel

Positioned at the base of engineering stack and essential layer of the Android framework. Never associates with developers or clients yet give a dimension of deliberation between gadget hardware and other engineering layers.

How about we check the functionalities of this layer to comprehend it's significance:

- Memory Management

- Power Management

- Hardware Abstraction

- Process Management

- Device Management

- Security Settings

- Network Stack

- Hardware Drivers

So this layer makes the OS moderately easy to us finishing all these profound works, would it say it isn't?
