WebView缓存文件遍历

File f = CacheManager.getCacheFileBaseDir();
 if (f.isDirectory()) {
    File[] flist = f.listFiles();
    long size = 0;
    for (File f : flist) {
	size = size + f.length();
         System.out.println(f.getName() + "________" + f.length());
    }
    if (size > 1000 * 1000) {
        myWeb.clearCache(true);
     }
}

可以清理掉webview加载网页时所保存的缓存文件.
