webkit下DownloadListener

看官方的API很简单,它是webkit下的一个接口,该接口就一个抽象方法:onDownloadStart:

public abstract void onDownloadStart (String url, String userAgent, String contentDisposition, String mimetype, long contentLength)

Added in API level 1

Notify the host application that a file should be downloaded

Parameters
url The full url to the content that should be downloaded
userAgent the user agent to be used for the download.
contentDisposition Content-disposition http header, if present.
mimetype The mimetype of the content reported by the server
contentLength The file size reported by the server

不用多解释。

下面是它的源码,也非常简单:
