Android JoystickView is a Custom View that simulates a Joystick for interactive applications for Android, as simple aim is allows access values of angle and power of the virtual Joystck movement.
1º Step: Download the JAR file at download
2º Step: Create a folder called "libs" on the root of your project and place the JAR file into.
It's enough to reffer and user the JoystickView library
If you want to change or upgrade some feature of the library, you should do:

2º Step Go to eclipse' menu FILE, after IMPORT.
3º Step: Now click in "Existing Project into Workspace"
4º Step: Click in Browse e search the source code folder where you placed after clone ou download.
5º Step: Setup with Next or/and Finish, ant the JoystickView is ready to you use in your applications.
6º Step: Import JoystickView in your applications.
To use JoystickView in your applications, simply add the lib to the classpath of your application:
7º Passo: Click with right button on your project go to PROPERTIES -> ANDROID and the ADD.
8º Step: Select JoystickView lib and click OK to finish.
From this point you can inflate the JoystickView in your layouts or referencing it in your Activities.

}
}
}, JoystickView.DEFAULT_LOOP_INTERVAL);
}
}This is an implementation of a custom android view that works like a Joystick, this view controls two variables, angle motion and power motion of the screen touch.
