buildChildDocumentsUri

static fun buildChildDocumentsUri(
    authority: String!, 
    parentDocumentId: String!
): Uri!

Build URI representing the children of the target directory in a document provider. When queried, a provider will return zero or more rows with columns defined by Document.

buildChildDocumentsUriUsingTree

static fun buildChildDocumentsUriUsingTree(
    treeUri: Uri!, 
    parentDocumentId: String!
): Uri!

Build URI representing the children of the target directory in a document provider. When queried, a provider will return zero or more rows with columns defined by Document.

However, instead of directly accessing the target directory, the returned URI will leverage access granted through a subtree URI, typically returned by Intent#ACTION_OPEN_DOCUMENT_TREE. The target directory must be a descendant (child, grandchild, etc) of the subtree.

This is typically used to access documents under a user-selected directory tree, since it doesn't require the user to separately confirm each new document access.

buildDocumentUri

static fun buildDocumentUri(
    authority: String!, 
    documentId: String!
): Uri!

Build URI representing the target Document#COLUMN_DOCUMENT_ID in a document provider. When queried, a provider will return a single row with columns defined by Document.

buildDocumentUriUsingTree

static fun buildDocumentUriUsingTree(
    treeUri: Uri!, 
    documentId: String!
): Uri!

Build URI representing the target Document#COLUMN_DOCUMENT_ID in a document provider. When queried, a provider will return a single row with columns defined by Document.

However, instead of directly accessing the target document, the returned URI will leverage access granted through a subtree URI, typically returned by Intent#ACTION_OPEN_DOCUMENT_TREE. The target document must be a descendant (child, grandchild, etc) of the subtree.

This is typically used to access documents under a user-selected directory tree, since it doesn't require the user to separately confirm each new document access.

buildRecentDocumentsUri

static fun buildRecentDocumentsUri(
    authority: String!, 
    rootId: String!
): Uri!

Build URI representing the recently modified documents of a specific root in a document provider. When queried, a provider will return zero or more rows with columns defined by Document.

    rootId: String!
): Uri!

Build URI representing the given Root#COLUMN_ROOT_ID in a document provider.

buildRootsUri

static fun buildRootsUri(authority: String!): Uri!

buildSearchDocumentsUri

static fun buildSearchDocumentsUri(
    authority: String!, 
    rootId: String!, 
    query: String!
): Uri!

Build URI representing a search for matching documents under a specific root in a document provider. When queried, a provider will return zero or more rows with columns defined by Document.

buildTreeDocumentUri

static fun buildTreeDocumentUri(
    authority: String!, 
    documentId: String!
): Uri!

Build URI representing access to descendant documents of the given Document#COLUMN_DOCUMENT_ID.

static fun createDocument(
    content: ContentResolver, 
    parentDocumentUri: Uri, 
    mimeType: String, 
    displayName: String
): Uri?

Create a new document with given MIME type and display name.

createWebLinkIntent

static fun createWebLinkIntent(
    content: ContentResolver, 
    uri: Uri, 
    options: Bundle?
): IntentSender?

Creates an intent for obtaining a web link for the specified document.

Note, that due to internal limitations, if there is already a web link intent created for the specified document but with different options, then it may be overridden.

Providers are required to show confirmation UI for all new permissions granted for the linked document.

If list of recipients is known, then it should be passed in options as Intent#EXTRA_EMAIL as a list of email addresses. Note, that this is just a hint for the provider, which can ignore the list. In either case the provider is required to show a UI for letting the user confirm any new permission grants.

Note, that the entire options bundle will be sent to the provider backing the passed uri. Make sure that you trust the provider before passing any sensitive information.

Since this API may show a UI, it cannot be called from background.

In order to obtain the Web Link use code like this:

<code>
  void onSomethingHappened() {
    IntentSender sender = DocumentsContract.createWebLinkIntent(<i>...</i>);
    if (sender != null) {
      startIntentSenderForResult(
          sender,
          WEB_LINK_REQUEST_CODE,
          null, 0, 0, 0, null);
    }
  }
 
  <i>(...)</i>
 
  void onActivityResult(int requestCode, int resultCode, Intent data) {
    if (requestCode == WEB_LINK_REQUEST_CODE &amp;&amp; resultCode == RESULT_OK) {
      Uri weblinkUri = data.getData();
      <i>...</i>
    }
  }
  </code>

deleteDocument

findDocumentPath

static fun findDocumentPath(
    content: ContentResolver, 
    treeUri: Uri
): DocumentsContract.Path?

Finds the canonical path from the top of the document tree. The Path#getPath() of the return value contains the document ID of all documents along the path from the top the document tree to the requested document, both inclusive. The Path#getRootId() of the return value returns null.

getDocumentId

static fun getDocumentId(documentUri: Uri!): String!

Extract the Document#COLUMN_DOCUMENT_ID from the given URI.

getDocumentMetadata

static fun getDocumentMetadata(
    content: ContentResolver, 
    documentUri: Uri
): Bundle?

Returns metadata associated with the document. The type of metadata returned is specific to the document type. For example the data returned for an image file will likely consist primarily or solely of EXIF metadata.

The returned Bundle will contain zero or more entries depending on the type of data supported by the document provider.

1. A DocumentsContract#METADATA_TYPES containing a String[] value. The string array identifies the type or types of metadata returned. Each value in the can be used to access a Bundle of data containing that type of data.
2. An entry each for each type of returned metadata. Each set of metadata is itself represented as a bundle and accessible via a string key naming the type of data.

Example:

<code>
      Bundle metadata = DocumentsContract.getDocumentMetadata(client, imageDocUri, tags);
      if (metadata.containsKey(DocumentsContract.METADATA_EXIF)) {
          Bundle exif = metadata.getBundle(DocumentsContract.METADATA_EXIF);
          int imageLength = exif.getInt(ExifInterface.TAG_IMAGE_LENGTH);
      }
  </code>

static fun removeDocument(
    content: ContentResolver, 
    documentUri: Uri, 
    parentDocumentUri: Uri
): Boolean

In contrast to deleteDocument it requires specifying the parent. This method is especially useful if the document can be in multiple parents.

renameDocument

static fun renameDocument(
    content: ContentResolver, 
    documentUri: Uri, 
    displayName: String
): Uri?
