Installing Android SDK

There are 10 easy steps to install Android SDK(Software Development Kit) on your computer and start coding.

1. Download the Android adt bundle free of cost from http://developer.android.com/sdk/index.html. There is also a link to install the SDK for platforms other than Windows.

After downloading extract the folder to your desired location.

To begin coding in Android latest JDK (www.oracle.com/technetwork/java/javase/downloads/index.html) must be pre installed on the system.

Then open Eclipse. It is the IDE for Android.

Set the location to store all the projects or applications you create termed as Workspace.
Then in the Menu Bar open Windows and then Android SDK Manager and download all the components under API level 17 ie 4.2 Jelly Bean and Extras.

• Name : <anything of your choice>
• Device : 4" WVGA 
• Target : Android 4.2.2 API 17
• CPU : ARM
• SD Card Size : 100MB
• Keep the default settings for the rest of fields. 
• Click OK.

Now your IDE is ready to build Android Apps.
