You can also do it this way:

byte[] getBytes (File file)
{
    FileInputStream input = null;
    if (file.exists()) try
    {
        input = new FileInputStream (file);
        int len = (int) file.length();
        byte[] data = new byte[len];
        int count, total = 0;
        while ((count = input.read (data, total, len - total)) > 0) total += count;
        return data;
    }
    catch (Exception ex)
    {
        ex.printStackTrace();
    }
    finally
    {
        if (input != null) try
        {
            input.close();
        }
        catch (Exception ex)
        {
            ex.printStackTrace();
        }
    }
    return null;
}
