In extras please download Android Support Repository and Android Support Library , if it is not already downloaded, as they are important for android projects.

Click next and select Blank Activity

Don’t change the Activity name, keep it MainActivity only.
And Click finish.

Your first project is ready you can run it now. 🙂 🙂

Now lets see the project structure of the hello world application.

This is the initial structure of your project :

The file activity_main.xml (res>layout>activity_main.xml) is the designer file or you can say the layout out file of your application.
It is basically the designer of your application.

In this file you will have to define all your views like TextView, Buttons, EditText and others.
You can further more add new xml files if you wish to and give its link in the activity.java file.

The file MainActivity.java (its under java folder) is the programmer file or you can say the coder of your application.

All the coding stuff is done over here in this file.

The file menu_main.xml [its in res>menu>menu_main.xml] is the option file of your application.

All the Menu (options) like Settings is defined in this file.

The file AndroidManifest.xml [its in app>manifests>AndroidManifest.xml] is the boss file of your application.

All the permission granting like Reading and Modification of storage, Using Hardware like Camera, Bluetooth,etc., Getting the Internet Access for your application is done in this file.
Further more for each activity made under java folder (.java) should be declared in this file.
Also the icons, themes your application will be using, the labels of activities and services should be used here.

Basically if you to add something new in your application, inform it to AndroidManifest file 😉 🙂
