public static String file2Base64(File file) {
    if (file == null) {
        return null;
    }
    String base64 = null;
    FileInputStream fin = null;
    try {
        fin = new FileInputStream(file);
        byte[] buff = new byte[fin.available()];
        fin.read(buff);
        base64 = Base64.encode(buff);
    } catch (FileNotFoundException e) {
        e.printStackTrace();
    } catch (IOException e) {
        e.printStackTrace();
    } finally {
        if (fin != null) {
            try {
                fin.close();
            } catch (IOException e) {
                e.printStackTrace();
