Work with files in external storage: Android App Development Essentials: Local Data Storage

The Android SDK designates persistent storage space as “external”. This should be confused with physical SD cards, which many contemporary Android devices support. The term “external storage” is used in contrast to “internal storage.” Internal is private to the app, and external is public-facing and visible to the user. You can read and write to internal files without any specific permissions, but to work with external storage the device user has to grant that permission.
