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;
    }
