       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 block
						e.printStackTrace();
					}  
		        byte[] program = bytestream.toByteArray();  
		        try {
						bytestream.close();
					} 
		        catch (IOException e) {
						// TODO Auto-generated catch block        
						e.printStackTrace();
					} 
                          OutputStream outputStream.write(program);
