Android save file path summary

1. Storage in Android can be divided into two categories: private storage and shared storage.

• Private Storage : Each application has its own private directory (/data/data/packageName) in the internal storage. Other applications cannot see it, and each other cannot access this directory.
• Shared Storage : Except for private storage, everything else is considered shared storage, such as media collection and SD card external application storage directory
