UiThread

@Documented  @Retention(value = CLASS)  @Target(value = ) 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.
