}
示例2: createForParcelFileDescriptor
import android.os.ParcelFileDescriptor; //导入方法依赖的package包/类
/**
* Creates a DocumentsArchive instance for opening, browsing and accessing
* documents within the archive passed as a file descriptor.
*
* <p>Note, that this method should be used only if the document does not exist
* on the local storage. A snapshot file will be created, which may be slower
* and consume significant resources, in contrast to using
* {@see createForLocalFile(Context, File, String, char, Uri}.
*
* @param context Context of the provider.
* @param descriptor File descriptor for the archive's contents.
* @param documentId ID of the archive document.
* @param idDelimiter Delimiter for constructing IDs of documents within the archive.
* The delimiter must never be used for IDs of other documents.
* @param Uri notificationUri Uri for notifying that the archive file has changed.
* @see createForLocalFile(Context, File, String, char, Uri)
