DocumentsContract


class DocumentsContract
kotlin.Any
   ↳ android.provider.DocumentsContract

Defines the contract between a documents provider and the platform.

To create a document provider, extend DocumentsProvider, which provides a foundational implementation of this contract.

All client apps must hold a valid URI permission grant to access documents, typically issued when a user makes a selection through Intent#ACTION_OPEN_DOCUMENT, Intent#ACTION_CREATE_DOCUMENT, or Intent#ACTION_OPEN_DOCUMENT_TREE.

    Added in API level 19
    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.

    Parameters

    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(

              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) {

    parentDocumentUri Uri: parent document of the document to remove. This value cannot be null.
