Android ScopedDirectoryAccess Sample
This sample demonstrates how to use the Scoped Directory Access API introduced in Android N to easily access to specific directories such as Pictures, Downloads instead of requesting READ_EXTERNAL_STORAGE or WRITE_EXTERNAL_STORAGE in your manifest.
This sample demonstrates how to use the Scoped Directory Access API that provides easy way to access specific directories instead of:
- Requesting READ_EXTERNAL_STORAGE or WRITE_EXTERNAL_STORAGE in your manifest, which allows access to all public directories on external storage.
- Using the Storage Access Framework, where the user usually picks directories via a System UI, which is unnecessary if you app always accesses to the same external directory.
To access to a specific directory, use a new Intent created using the StorageVolume class like following:
StorageManager sm = getSystemService(StorageManager.class); StorageVolume volume = sm.getPrimaryVolume(); Intent intent = volume.createAccessIntent(Environment.DIRECTORY_PICTURES); startActivityForResult(intent, request_code);
Note that the argument passed to StorageVolume.createAccessIntent needs to be one of the values of Environment.DIRECTORY_*.
Once the user grants the access,
onActivityResult override will be called with a
result code of
Activity.RESULT_OK and an intent data that contains the URI representing
- Android SDK 24
- Android Build Tools v27.0.2
