Designing my first android app

ANDROID APPLICATION DEVELOPMENT FOR BEGINNERS

1) INSTALLING ANDROID SDK

You will need the text editor for designing your android application. ECLIPSE IDE is recommended as I am working with it. Trust me guys, it’s very easy to use the eclipse in order to design your android apps.

You can download the eclipse IDE from the below link

https://dl.google.com/android/adt/adt-bundle-windows-x86-20131030.zip

It is totally safe to download the bundle from the above link, don’t use any other link, it might be malicious.

2) INSTALLING ADT PLUGIN for Eclipse

This plugin is required to integrate your eclipse IDE with the android SDK. With the help of this plugin, you can make your eclipse to design apps for android platform.

This ADT Plugin is installed into the eclipse IDE.

This should be done once you extract the above ADT bundle and start the eclipse from the same.

This plugin can be installed in simple steps as follows.
