关于此限制的说明：
https://developer.android.com/reference/android/content/Context.html#MODE_WORLD_READABLE
MODE_WORLD_READABLE
Creating world-readable files is very dangerous, and likely to cause security holes in applications. It is strongly discouraged; instead, applications should use more formal mechanism for interactions such as ContentProvider, BroadcastReceiver, and Service. There are no guarantees that this access mode will remain on a file, such as when it goes through a backup and restore.
File creation mode: allow all other applications to have read access to the created file.
As of N attempting to use this mode will throw a SecurityException.
