Lots of tools are available over the web but we recommend you to use Eclipse for learning JAVA since it is the most common tool used for Android Development alongwith Android Studio. In this tutorial we go through the steps needed to build your first Android app.
You will create a simple UI, add some Java code, and then run your app. Eclipse is the most popular Open Source Java IDE. More developers use Eclipse than any other tool for Java Programming. In this course, we take you on a fun ride with Eclipse. Eclipse is a very popular development environment (IDE) for Java and the preferred IDE for Android development.
It’s freely available for Windows, Mac, and Linux operating systems. For complete instructions on how to install Eclipse (including which versions are supported) and the Android SDK, see the Android developer website. In this series you'll learn about Android development from the beginning.
In the first section we setup the Android SDK and Eclipse. In this part we will acquaint ourselves with the Eclipse software. Eclipse is an IDE (Integrated Development Environment) for Java.
