Annotation Type FragmentArg

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

Use on any native, Parcelable or Serializable field in an EFragment 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 argument. If not set, the field or method name will be used as the key.

When FragmentArg 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.

Example :

 @EFragment
 public class MyFragment extends Fragment {
 
        @FragmentArg
        String myMessage;
 
        @FragmentArg
        void singleInjection(String myMessage) {
                // do stuff
        }

        void multiInjection(@FragmentArg String myMessage, @FragmentArg String myMessage2) {
                // do stuff
        }
 }
 
 @EActivity
 public class MyActivity extends Activity {
 
        @AfterViews
        void init() {
                MyFragment myFragment = MyFragment_.builder() //
                                .myMessage("Hello") //
                                .build();
        }
 }
