Unlike the other answers, this solution allows you to upload without having to create a file for the data on the device first.

 // Create a File containing any metadata changes.
 File metadata = new File().setName(name);

 // Convert content to an AbstractInputStreamContent instance.
 ByteArrayContent contentStream = ByteArrayContent.fromString("text/plain", content);

// Update the metadata and contents.
mDriveService.files().update(fileId, metadata, contentStream).execute();
