I'm developping an application that provides users with an interface where they can download files from our Google Cloud Storage. I wrote unit tests and I could connect to the storage and a file was downloaded. 

Now that I'm (almost) finished with my interface, I wanted to test the whole application. But now I notice I don't really download the file, I download a file with META data about the file I want to download. Something like:

```
{
 "kind": "storage#object",
 "id": "xxxxxxxxxxx/Homer.png/xxxxxxxxxxxx",
 "selfLink": "https://www.googleapis.com/storage/xxxxxxxxxxxxxxxx/Homer.png",
 "name": "Homer.png",
 "bucket": "xxxxxxxxxxxxxxx",
 "generation": "xxxxxxxxxxxxxxx",
 "metageneration": "1",
 "contentType": "image/png",
 "updated": "2014-07-17T08:37:28.026Z",
 "storageClass": "STANDARD",
 "size": "xxxxx",
 "md5Hash": "xxxxxxxxxxxxxxxxxxxxx",
 "mediaLink": "https://www.googleapis.com/download/storage/xxxxxxxxxxxxxxx/o/Homer.png?generation=xxxxxxxxxxxxxxxxx&alt=media",
 "owner": {
  "entity": "user-xxxxxxxxxxxxxxxxxxxxxxxxxxxx",
  "entityId": "xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx"
 },
 "crc32c": "xxxxxxxxxx",
 "etag": "xxxxxxxxxxxxx"
}

```

I'm wondering what I'm doing wrong, this is the code I'm using to download the file:

```
public byte[] getFileAsByteArray(String bucketName, String fileName)
        throws GoogleAppManagerException {
        Storage storage = null;
        try {
            storage = getStorage();
        } catch (GeneralSecurityException e) {
            throw new GoogleAppManagerException(SECURITY_EXCEPTION + e.getStackTrace(), e);
        } catch (IOException e) {
            throw new GoogleAppManagerException(IO_EXCEPTION + e.getStackTrace(), e);
        }
        Get get = null;
        ByteArrayOutputStream outputStream = new ByteArrayOutputStream();
        try {
            get = storage.objects().get(bucketName, fileName);
            get.executeAndDownloadTo(outputStream);
        } catch (IOException e1) {
            throw new GoogleAppManagerException(IO_EXCEPTION + e1.getStackTrace(), e1);
        }
        return outputStream.toByteArray();
    }

```
