Answer


If your app uses the media store, you need to ask for permission to access other apps' media files. Your app needs to request the READ_EXTERNAL_STORAGE permission to access any media files on your device.

The framework supports different use cases for working with files. It explains how to perform operations at a location that the user has selected.

The storage access framework supports a number of use cases.

The following sections explain how to use certain things.

The user can choose a location to write the contents of a file if they use the ACTION_CREATE_DOCUMENT intent action to load the system file chooser.

The process is similar to the one used in the "Save As" dialog boxes.

The file name and MIME type should be specified when configuring intent. The file picker should display the extra-INITIAL_URI intent if the file or directory is specified.

The following code shows how to invoke the intent to create a file.

The app can be used to store data that users might want to share with other people, or to import data from other documents. A user can open a productivity document or book saved as an EPUB file.

The user can choose the file to open by calling the action_open_ document intent. To display only supported file types, specify a MIME type.

You can specify the file's URI in order for the file picker to show it on the first load.

The following code shows how to invoke the intent to open a PDF document.

You can't use the intent action to prompt the user to select individual files from the following directories.

Group of files in a directory hierarchy are managed by file management and media creation applications. The ACTION_OPEN_DOCUMENT_TREE intent action allows the user to grant access to an entire directory tree, with some exceptions starting with the latest version of the app. The app can access any file in a directory.

The files in the directory the user selects are what your app gets access to. You don't have access to the files of other apps that are located outside the directory that the user chose.

Users can choose the exact content they want to share with the app.

The file picker should display the EXTRA_INITIAL_URI intent if you specify the URI of the directory.

The following code shows how to open a directory.

You can't use the ACTION_OPEN_DOCUMENT_TREE intent action to request access to the following directories.

You can't use the intent action to prompt the user to select individual files from the following directories.

You can retrieve the URI of a selected item after the user has selected a file or directory.

Your app can perform various operations on it if you get a reference to the URI of the selected element. You can access the item's data, change it or remove it.

The user can see how to perform actions on the files they pick.

Different content providers allow you to do different things with documents.

Check the value of Document.COLUMN_FLAGS to determine which operations a provider supports. The provider's options can only be seen in the app'sUI.

When the app opens a file, the system grants it a permission that lasts until the device is rebooted. If you have an image-editing app, you want users to be able to access the 5 images they recently edited from within it.

If the device restarts, you should send the user back to the system picker to find the files.

To retain access to files after a device restarts and create a better user experience, your app can grab the Persistent URI permission offered by the system, as shown in the following code snippets.

You can access the document's data if you have the document's URI. The document's Metadata is captured and recorded by this snippet.

You can open a document with a reference to its URI. There are examples in this section for opening a stream.

The code shows how to open a Bitmap file.

You can use an image view to display it after opening the bitmap.

The code snippets show how to open an InputStream object. The lines from the file are read into a string.

The storage access framework can be used to edit a text document.
