对activity主要进行了一下处理
-
- 设置webViewChromeClient
-
- 实现webViewChromeClient.onShowCustomView方法，该方法是webview全屏时被调用的方法, 方法具体内容参考代码
-
- 实现webViewChromeClient.onShowCustomView方法，该方法是webview退出全屏时被调用的方法，方法具体内容参考代码
-
- 设置webViewClient防止使用浏览器打开
注：statusBar的处理可能在兼容性方面有些问题，需要自己调整下
- 使用基于x5内核或者chrome内核的webview
- 安卓自带webview播放器默认使用hlsjs
前端处理
provider: ['hlsjs']
原因
FileSaver.saveAs(docUrl, filename + '.' + ext) 在webview中不支持
现在方案是移动端统一复制链接, 业务代码修复
DownloadBtn组件判断许覆盖Android
if (isWeixin || Browser.isiOS || Browser.isAndroid) {
} else {
}
长按识别需要在客户端完成下载, 示例代码

客户端增加文档读写权限 上传图片时需要动态获取权限
添加权限
AndroidManifest.xml
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.SET_WALLPAPER"/>
动态调用/使用
