File:

That is, the so-called file storage method, which is commonly used to store a large amount of data, but the disadvantage is that it will be difficult to update the data.

ContentProvider:

A data storage method that can be shared by all applications in Android system. Because the data is usually private among applications, this storage method is seldom used, but it is also an indispensable storage method. For example, audio, video, pictures and address books can generally be stored in this way. Each Content Provider will provide a public URI (wrapped as a Uri object). If the application has data to share, it needs to use Content Provider to define a URI for the data, and then other applications will pass in the URI through Content Provider to manipulate the data.
