@Target([AnnotationTarget.FUNCTION, AnnotationTarget.PROPERTY_GETTER, AnnotationTarget.PROPERTY_SETTER, AnnotationTarget.CONSTRUCTOR, AnnotationTarget.CLASS, AnnotationTarget.FILE, AnnotationTarget.VALUE_PARAMETER]) class UiThread
androidx.annotation.UiThread

Denotes that the annotated method or constructor should only be called on the UI thread. If the annotated element is a class, then all methods in the class should be called on the UI thread.

Example:

 @UiThread public abstract void setText(@NonNull String text) { ... } 

Note: Ordinarily, an app's UI thread is also the main thread. However, under special circumstances, an app's UI thread might not be its main thread; for more information, see Thread annotations.
