1 2 Android ScopedDirectoryAccess Sample 3 =================================== 4 5 This sample demonstrates how to use the Scoped Directory Access API introduced in Android N 6 to easily access to specific directories such as Pictures, Downloads instead of requesting 7 READ_EXTERNAL_STORAGE or WRITE_EXTERNAL_STORAGE in your manifest. 8 9 Introduction 10 ------------ 11 12 This sample demonstrates how to use the Scoped Directory Access API that provides easy way to 13 access specific directories instead of: 14 - Requesting READ_EXTERNAL_STORAGE or WRITE_EXTERNAL_STORAGE in your manifest, which allows 15 access to all public directories on external storage. 16 - Using the Storage Access Framework, where the user usually picks directories via a System UI, 17 which is unnecessary if you app always accesses to the same external directory. 18 19 To access to a specific directory, use a new Intent created using the StorageVolume class like 20 following: 21 22 ``` 23 StorageManager sm = getSystemService(StorageManager.class); 24 StorageVolume volume = sm.getPrimaryVolume(); 25 Intent intent = volume.createAccessIntent(Environment.DIRECTORY_PICTURES); 26 startActivityForResult(intent, request_code); 27 ``` 28 29 Note that the argument passed to StorageVolume.createAccessIntent needs to be one of the 30 values of Environment.DIRECTORY_\*. 31 32 Once the user grants the access, `onActivityResult` override will be called with a 33 result code of `Activity.RESULT_OK` and an intent data that contains the URI representing 34 the directory. 35 36 Pre-requisites 37 -------------- 38 39 - Android SDK 24 40 - Android Build Tools v24.0.1 41 - Android Support Repository 42 43 Screenshots 44 ------------- 45 46 <img src="screenshots/1.png" height="400" alt="Screenshot"/> <img src="screenshots/2.png" height="400" alt="Screenshot"/> <img src="screenshots/3.png" height="400" alt="Screenshot"/> 47 48 Getting Started 49 --------------- 50 51 This sample uses the Gradle build system.
