Annotation Type InjectExtra

@Retention(value=RUNTIME)
@Target(value={FIELD,PARAMETER,METHOD})
public @interface InjectExtra

Indicates that a variable member of a class (whether static or not) should be injected with an Android extra. The value is compulsory, and correspond to the key of the extra.

The extra must exists when the activity is injected, unless you specify optional=true in the InjectExtra annotation. If optional is set to true and no extra is found, no value will be injected in the field.

The default behavior of the InjectExtra annotation is to forbid null values. However, if you wish to allow injection of null values, you should use the Nullable annotation.

You can define a default value in Java when the extra is optional :
