The android developer site is a great place to start from: http://developer.android.com/guide/basics/what-is-android.html

After you read the basics, start with a tutorial: http://developer.android.com/resources/browser.html?tag=tutorial

If you have any specific question after that, when you start implementing your application, you are welcome to ask.
