How Android permanently saves data

Background:
In Android, data is stored in the following ways:
Content Provider (implemented using SQLite), SQLite, SharedPreferences (implemented using XML), files, and networks.

In today's project, you need to save a permanent data to your local device.
The storage methods are tested.
Among them, SharedPreferences, SQLite, and Content Provider will delete the file when you choose Settings> Application Management> clear data. So it is not safe.
File System: If the SD card is broken or is unplugged, data is lost.

Solution:
Save data to the SD card (considering that the SD card can store a variety of complex data, and the capacity is larger than other storage methods ),
To obtain data, first obtain the data from the SD card. If the data is not stored locally.
