Remarks
Builds an intent to give access to a standard storage directory or entire volume after obtaining the user's approval.
When invoked, the system will ask the user to grant access to the requested directory (and its descendants). The result of the request will be returned to the activity through the onActivityResult method.
To gain access to descendants (child, grandchild, etc) documents, use DocumentsContract#buildDocumentUriUsingTree(Uri, String), or DocumentsContract#buildChildDocumentsUriUsingTree(Uri, String) with the returned URI.
If your application only needs to store internal data, consider using Context#getExternalFilesDirs(String) Context.getExternalFilesDirs, Context#getExternalCacheDirs(), or Context#getExternalMediaDirs(), which require no permissions to read or write.
Access to the entire volume is only available for non-primary volumes (for the primary volume, apps can use the android.Manifest.permission#READ_EXTERNAL_STORAGE and android.Manifest.permission#WRITE_EXTERNAL_STORAGE permissions) and should be used with caution, since users are more likely to deny access when asked for entire volume access rather than specific directories.
This member is deprecated. Callers should migrate to using Intent#ACTION_OPEN_DOCUMENT_TREE instead. Launching this Intent on devices running android.os.Build.VERSION_CODES#Q or higher, will immediately finish with a result code of android.app.Activity#RESULT_CANCELED.
