Your IDE should also have created a main layout file that the Main class uses to create the application's user interface.

The Main class plays a key role when your application is launched. The name of this class may vary depending on which IDE you're using. If your IDE supports Android development, it'll have created a Main class for you.

For this tutorial, I'll be using IntelliJ IDEA. Start a new Android project in your favorite IDE (Integrated Development Environment) for Android development. We'll use the shake gesture to randomly generate six Lottery numbers and display them on the screen using a pretty animation. In this tutorial, we'll use a gesture that you find in quite a few mobile applications, the shake gesture.

For example, have a look at these app templates on Envato Market. Quite a few apps are now making use of the accelerometer. I find that using gestures can bring an Android application to life, making it more interesting and exciting for the user. This is especially true for touch devices, such as smartphones and tablets. Using gestures often feels more natural than interacting with a user interface through mouse and keyboard. But times have changed and interacting with hardware components is becoming more and more common.

I'll explain what an accelerometer is and why it may be something you want to take advantage of in your Android applications.īefore the dawn of smartphones, one of the few hardware components applications could interact with was the keyboard. In this tutorial, we are going to explore how to use the accelerometer, one of the many hardware sensors of modern smartphones, in an Android application.
