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.

Introduction

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 the directory.
