項目說明：最近在開發(fā)Android原生嵌套H5實現(xiàn)混合開發(fā)，剛開始采用原生的WebView各種兼容性問題，之后決定采用騰訊的x5瀏覽器來開發(fā)，遇到的一些問題列一下：

• x5Webview與H5的交互問題
• x5同步cookie問題
• WebView加載進度條問題處理
• H5調(diào)用Android攝像頭進行錄制視頻、H5調(diào)用Android相機進行拍照
• x5WebView-WebChromeClient的方法onShowFileChooser只執(zhí)行一次的問題
• X5WebView的Setting需要配置那些東西

先看效果圖
