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.
