Shows an Appodeal ad. By default, Appodeal automatically caches ads in the background, so there is normally no need to load ads in advance of calling this method. However, automatic caching may be disabled when calling appodeal.init().


Appodeal SDK can’t show ads in offline mode! You will get "adsRequest" Event with phase "failed" If you call this method without internet connection.
