Может кто-то, пожалуйста, помогите мне. У меня возникают трудности с LoadUrl и javascript.LoadUrl Javascript не загружается вообще
Код, показанный, кажется, работает sorta ok (убивает приложение, а затем пытается снова заставить его работать) на моем старом HTC, работающем под управлением 2.3, однако мой Xperia Z, который запускает последний Android, застрял на «Попытке получить комментарии».
Раздел кода он торчит на это InjectJavaScript(), где это не удается LoadUrl (я знаю, что это как onPageFinished никогда не называется). Странная вещь - часть статистики кода работает отлично и ее идентична.
К сожалению его довольно грязный код ...
