Android4.4 was previously on sd card/Android/data/com.ifeng.newvideo/files/video; But when Android4.4 was code-named KitKat (Nestle's chocolate brand Kit Kat), the system brought many new functions.

However, it should be noted that the system may turn the SD card that you have been using normally into a useless "display", because according to the improvement of the new API, applications will no longer be able to write files to the SD card. So I wrote a specific directory in the system:/data/user/0/com. ifeng.newvideo/files/video.
