Android Dropbox API file download

Question

I am currently working on an android app that is to support the android dropbox api. I have got it working so that it sends a file from the android sd card to a dropbox folder. I then later on need to be able to download this file and save it to the phone sd card again.

How can I download the file from Dropbox and save it to the device, there is very little to no documentation about the android api.

Thanks for any help you can provide.

private boolean downloadDropboxFile(String dbPath, File localFile) throws IOException{

    BufferedInputStream br = null;
    BufferedOutputStream bw = null;

    try {
        if (!localFile.exists()) {
            localFile.createNewFile(); //otherwise dropbox client will fail silently
        }

        FileDownload fd = api.getFileStream("dropbox", dbPath, null);
        br = new BufferedInputStream(fd.is);
        bw = new BufferedOutputStream(new FileOutputStream(localFile));

        byte[] buffer = new byte[4096];
        int read;
        while (true) {
        read = br.read(buffer);
        if (read <= 0) {
        break;
        }
        bw.write(buffer, 0, read);
        }
    } finally {
        //in finally block:
        if (bw != null) {
            bw.close();
        }
        if (br != null) {
            br.close();
        }
    }

    return true;
}
