/**
 * <p>
 * Should be used on {@link android.app.Activity} classes to enable usage of
 * AndroidAnnotations.
 * </p>
 * <p>
 * Your code related to injected beans should go in an {@link AfterInject}
 * annotated method.
 * </p>
 * <p>
 * Any view related code should happen in an {@link AfterViews} annotated
 * method.
 * </p>
 * <p>
 * If the class is abstract, the enhanced activity will not be generated.
 * Otherwise, it will be generated as a final class. You can use
 * AndroidAnnotations to create Abstract classes that handle common code.
 * </p>
 * <p>
 * The annotation value should be one of R.layout.* fields. If not set, no
 * content view will be set, and you should call the
 * <code>setContentView()</code> method yourself, in <code>onCreate()</code>
 * </p>
 * <blockquote>
 * 
 * Example :
 * 
 * <pre>
 * &#064;EActivity(R.layout.main)
 * public class MyActivity extends Activity {
 * 
 * 	public void launchActivity() {
 * 		// Note the use of generated class instead of original one
 * 		MyActivityTwo_.intent(this).startActivity();
 * 	}
 * }
 * 
 * &#064;EActivity(R.layout.main)
 * public class MyActivityTwo extends Activity {
 * 
 * 	&#064;Bean
 * 	MyBean myBean;
 * 
 * 	&#064;ViewById
 * 	TextView myTextView;
 * 
 * 	&#064;AfterInject
 * 	void init() {
 * 		myBean.doSomeStuff();
 * 	}
 * 
 * 	&#064;AfterViews
 * 	void initViews() {
 * 		myTextView.setText(&quot;test&quot;);
