Android & Android App development( part-1)

Hello Everyone & welcome to all.

Today I am here with my new post related to android & android applications. So, here we learn How to become an android application developer.

Before, we start to study android app development, we need to know some important topics and that topics are as below:

1) What is android?

2) What is Application?

3) What is Android Application?

4) What is use of android application? Why & where we use?

5) How we develop android application?

Now, probably we think that if we become an app developer then what we will do next. Basically, we think it’s time for creating an app & launch it in market. But Building the app is only half the battle, after we have built our app we need to learn “How to launch & optimize the app with market condition and its popularity’’. So, we must have to learn production development rules related to app development to become a good developer.

Now let look into the questions one-by-one :

What is android?

Android is an open source operating system used for smart-phones and tablet computers.

Android was found at Palo alto, California(US) October,2003 by Andy Rubin, Rich Miner, Nick Sears, Charis White. The name Android is defined based on the name of Andy Rubin. Android is one of the most widely used mobile operating system.

When Android came in market as Android OS. It was developed by google & later it was handled & updated by OHA (Open Handset Alliance). OHA is an organization of few companies and it is leaded by Google. Android is based on Linux kernel. Android was written in Java so Java language is used to write android code with the help of another languages like C & C++ too.

Android has various versions since its first advent. Some of the android version as nougat, marshmallow, cupcake, Blender, Astro etc. It’s nothing but Android code names.

The table below shows the various Android versions along with their code-names and API Levels.

*Android version*	*Android code-name*	*API* *LEVEL*
1.5	Cupcake	3
1.6	Donut	4
2.1	Eclair	7
2.2	Froyo	8
2.3.3-2.3.7	Gingerbread	9 & 10
3.1 & 3.3	Honeycomb	12 &13
4.0.3-4.0.4	Ice-cream & Sandwich	15
4.1,4.2 & 4.3	Jelly bean	16,17,17
4.4	KitKat	19
5.0 & 5.1	Lollipop	21 & 22
6.0	Marshmallow	23
7.0 & 7.1.2	Nougat	24 & 25

We are discussing API LEVEL here just because while we create an android app it is created based on the API level.

That’s all for now, we will discuss another topic later in my new post. Today’s post is only for introduction purpose. I will explain all topics step by step in brief later.

Till that good bye
