Which is better for storing large files?

Question

Android

Bundle, External Storage or all the same a DB?

Answer 1

If there is really a lot of data, then it depends on their structure. If there is a structure (these are many identical records), then, of course, the database. If it's just a big binary (audio, video, etc), then, of course, a file in external storage.
Bundle does not fit under any sauce, it is an abstraction for short-term storage of state (for example, between screen openings or configuration changes).
