Potrzebuję odtwarzać wideo html5 w widoku WebView. Znalazłem technikę, która ma działać, ale działa tylko sporadycznie (patrz koniec pytania). Kiedy to nie działa, onShowCustomView nie jest wywoływany. Czy ktokolwiek widzi przyczynę, że to nie działa lub sugeruje alternatywę?Jak mogę odtwarzać wideo inline html5 w WebView?
