// 获取scared的文件夹路径
通过Context.getExternalFilesDir()方法可以获取到 SDCard/Android/data/你的应用的包名/files/ 目录，一般放一些长时间保存的数据
通过Context.getExternalCacheDir()方法可以获取到 SDCard/Android/data/你的应用包名/cache/目录，一般存放临时缓存数据
// 获取手机存储空间的文件夹路径 /data/data/et.tsingtaopad/files/photo/
String path = getFilesDir().getAbsolutePath() + File.separator + "photo"+ File.separator;
getCacheDir()方法用于获取/data/data/<application package>/cache目录
getFilesDir()方法用于获取/data/data/<application package>/files目录
//--------------------------------------------------------------------
/**
* 获取缓存文件夹
* 通常都会存放在 /sdcard/Android/data/<application package>/cache 这个路径下面，
* 但同时我们又需要考虑如果这个手机没有SD卡，或者SD正好被移除了的情况，因此专门写一个方法来获取缓存地址
