"A complete programming environment for developing Android apps."
Android SDK is the perfect tool if you want to become a developer of Android apps, either professionally or just to have as a "hobby", creating that app you've always wanted to exist, or Android games, who knows, maybe you'll develop the next "Angry Birds" and get rich.
Because with Android SDK you get, in a single download, a visual programming environment for Android with a complete toolkit and all the API libraries you'll need to schedule anything for Android using Java (so you also need to have the Java programming environment installed in your PC), along with complete documentation so as to learn to program for Android with Android SDK.
In addition, Android SDK includes several examples of apps created by other users, for you to use to learn how to create your own, or integrate them, programs to simulate the Android environment, where to find "bugs" and test your application that's already created, test the code, or test how the application is finally, among many other possibilities. This program is very easy to download, install and then use, through its friendly and intuitive user interface. You don't need any technical experience at all to get the most out of it.
