I need to get an array of bytes of a File, so I need to know the length of the file. How can I get a file from the assets or raw directory ?

看来最正常的是获得的InputStream，但不能获取文件的长度。

    ByteArrayOutputStream stream = new ByteArrayOutputStream();
    int length;
    while ((length = inputStream.read()) != -1) {
        stream.write(length);
    }
    return stream.toString();
