Necesito reproducir un video html5 en línea en una WebView. Encontré una técnica que debería funcionar, pero solo funciona esporádicamente (ver el final de la pregunta). Cuando no funciona, no se llama a OnShowCustomView. ¿Alguien puede ver una razón por la cual esto no está funcionando o sugerir una alternativa?¿Cómo puedo reproducir video html5 en línea en una WebView?
