Experienced Android app developers probably know what a pain it was to setup a development environment for Android. But now, with the ADT (Android Developer Tools) Bundle, setting up your development environment is a breeze. Seriously. You just need to download the appropriate bundle for your platform (Windows, Mac or Linux), unzip and launch Eclipse. That’s it.
Two minutes, you would have already created a simple Android app with some text on it and images in it. The bundle also includes all the components to create an emulator and launch your app, if you don’t have a device.
Of course, if you prefer to develop your Android apps on another version of Eclipse, you would have to set up everything manually. Have a look on the Android developer’s website for more information.
