A mode that opens the contents only for reading.
A mode that opens the contents for reading and writing.
A mode that opens the contents only for writing.
This method is deprecated.
Use
openFile(DriveFile, int) or
openFile(DriveFile, int, OpenFileCallback) instead.
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).
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().
| apiClient | The GoogleApiClient
to service the call. |
|---|---|
| mode | Describes the mode in which to open the file. Possible values are
MODE_READ_ONLY, MODE_READ_WRITE
and MODE_WRITE_ONLY. |
| listener | An optional listener that will announce progress as the file is downloaded. If
you don't care about progress, provide null. |
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).
