       利用inputstream读取二进制文件，并转成outputstream：

                          InputStream inputStream = getResources().openRawResource(R.raw.file3);        ByteArrayOutputStream bytestream = new ByteArrayOutputStream();          int ch;          try { while ((ch = inputStream.read()) != -1) {   bytestream.write(ch);  }}         catch (IOException e) {// TODO Auto-generated catch blocke.printStackTrace();}          byte[] program = bytestream.toByteArray();          try {bytestream.close();}         catch (IOException e) {// TODO Auto-generated catch block        e.printStackTrace();}                           OutputStream outputStream.write(program);
