Ok then...
Follow these steps to create a basic “Hello world” app.
1. First of all you need to have a framework and particular tool for developing. Either you can use Eclipse or Android studio as a framework. And also download latest SDK tools using SDK manager.
(These are the links from where you can download framework and tools.
For Eclipse : https://eclipse.org/downloads/
For Android studio: https://developer.android.com/sdk/index.html
For SDK tool : https://developer.android.com/sdk/index.html#top )
I suggest it is better to use Android studio.

2. See that
your has jdk latest version. To see whether jdk installed in your computer goto
cmd and type javac –version, if jdk is not
installed or older versions of jdk is present then download jdk (http://www.oracle.com/technetwork/java/javase/downloads/index.html). After installing jdk check whether
your Android studio or Eclipse and SDK manager are successfully installed. If
they show any error message like launcher script does not find where Java is
installed. Then you need to setup a path to current location Select Start menu > Computer > System
Properties > Advanced System Properties.
Then open Advanced tab > Environment
Variables and add a new system variable JAVA_HOME that points to your
jdk folder, for example C:\Program Files\Java\jdk1.7.0_21.
3.Launch
Android studio or Eclipse framework so that you can enter into an environment
where you can develop your first android app.
->Goto File > New project
A configure window will appear give a name for the application for example “HelloWorld” and company domain as “helloworld.com” and project location is the space where you wish to store your project so provide project location and click on Next.

After that select minimum SDK level
i.e select Android 2.2 (API 8) then click NEXT.
5. After
