WebView页面加载在webviewglue: nativeDestroy视图后失败
WebView页面加载在webviewglue: nativeDestroy视图后失败
提问于 2013-11-11 17:00:16
我在一些安卓设备上有以下问题(我现在可以在Galaxy和GalaxyS4上复制它)：WebView无法加载页面。没有错误或onReceivedError调用，但也不会触发onPageFinished。我实现了进度回调，以查看页面是否正在加载。下列留在日志中：

原因是，我有一个WebView预加载器，它显示WebView，如果它是在加载和发送回调消息时完成的。WebView本身没有分配给变量，而是由垃圾收集器在某些设备上删除。
