android.webkit.CacheManager建议看看这个类The class CacheManager provides the persistent cache of content that is received over the network. The component handles parsing of HTTP headers and utilizes the relevant cache headers to determine if the content should be stored and if so, how long it is valid for. Network requests are provided to this component and if they can not be resolved by the cache, the HTTP headers are attached, as appropriate, to the request for revalidation of content. The class also manages the cache size(看到这句了没).参考下吧:CacheManager.getCacheFileBaseDir();首先声明我没清除过,但上面这句代码是得到缓冲路径的应该没错.
