Annotation Type Extra

@Retention(value=CLASS)
 @Target(value={FIELD,METHOD,PARAMETER})
public @interface Extra

Use on any native, Parcelable or Serializable field in an EActivity annotated class to bind it with Android's arguments. If Parceler is on the classpath, extras annotated with @Parcel, or collections supported by Parceler will be automatically marshaled using a Parcelable through the Parcels utility class.

The annotation value is the key used for extra. If not set, the field or method name will be used as the key.

When Extra is used, the intent builder will hold dedicated methods for each annotated fields.

Your code related to injected extra should go in an AfterInject annotated method.

Calling Activity#setIntent(Intent) will automatically update the annotated extras.

Example :

 @EActivity
 public class MyActivity extends Activity {
 
        @Click
        void buttonClicked() {
                MyExtraActivity_.intent(this) //
                                .myMessage("test") //
                                .startActivity();
        }
 }
 
 @EActivity
 public class MyExtraActivity extends Activity {
 
        @Extra
        String myMessage;
 
        @Extra
        void singleInjection(String myMessage) {
                // do stuff
        }

        void multiInjection(@Extra String myMessage, @Extra String myMessage2) {
                // do stuff
        }
 
        @AfterInject
        void init() {
                Log.d("AA", "extra myMessage = " + myMessage);
        }
 }
