public annotation MainThread
Denotes that the annotated method should only be called on the main thread. If the annotated element is a class, then all methods in the class should be called on the main thread.
Example:
@MainThread
public void deliverResult(D data) { ... }
Note: Ordinarily, an app's main thread is also the UI thread. However, under special circumstances, an app's main thread might not be its UI thread; for more information, see Thread annotations.
