Public Methods

public abstract PendingResult<DriveApi.DriveContentsResult> open (GoogleApiClient apiClient, int mode, DriveFile.DownloadProgressListener listener)

Opens the DriveContents that are associated with this file for read and/or write. The returned file is a temporary copy available only to this app. The contents must be closed via commit(GoogleApiClient, MetadataChangeSet) or discard(GoogleApiClient).

Availability

The contents are returned when they are available on the device in their entirety. Content is returned from the cache if it is available and up to date, otherwise it will be downloaded from the server. To listen for download progress, provide a DriveFile.DownloadProgressListener. Note: If the download fails, e.g. due to the device going offline, the cached version will be returned (if available).

Note: to open the file in edit mode, the user must have edit access. See isEditable().

Parameters
apiClient GoogleApiClient: The GoogleApiClient to service the call.
mode int: Describes the mode in which to open the file. Possible values are MODE_READ_ONLY, MODE_READ_WRITE and MODE_WRITE_ONLY.
listener DriveFile.DownloadProgressListener: An optional listener that will announce progress as the file is downloaded. If you don't care about progress, provide null.
Returns
PendingResult<DriveApi.DriveContentsResult> A PendingResult which can be used to retrieve the DriveContents when they are available. If isSuccess() returns true, it is recommended to check getStatusCode(), since two possible values are considered success: SUCCESS which means that the returned DriveContents is up to date, or SUCCESS_CACHE which means that the returned DriveContents is a cached version, since the most up to date version could not be downloaded to the device (for example, due to connectivity).
