Android 清理大师产品的具体实现（一）QQ专清

首先我们先解析下目录：

一个正常的QQ用户安装下，使用后，在文件夹中到底发生了什么事情？

我们从文件管理器中tencent-MobileQQ-下打印所有的文件夹以及文件：

String filePath = Environment.getExternalStorageDirectory()+"/tencent/MobileQQ/";
FileUtils.getFilesAllName(filePath);

//获取指定目录下的所有文件夹
public static List getFilesAllName(String path) {
    File file=new File(path);
    File[] files=file.listFiles();
    if (files == null){Log.e("error","空目录");return null;}
    List s = new ArrayList<>();
    for(int i =0;i

打印出来的结果是：

接下来我们一步步解析我们QQ专清所涉及到的文件夹；

先来看下需求：

1、垃圾文件

2、临时缓存（浏览朋友圈产生的缓存垃圾）

3、头像缓存（联网可重新下载）

4、空间缓存（浏览空间所产生的图片缓存）

5、短视频缓存（浏览视频、空间、微视所产生）

深度清理：

视频、图片（聊天、保存）、表情（自定义、下载）、语音、文件

我们实现的逻辑思路是可以这么出发：
