发送的android BMP使用套接字 [英] android sending bmp using sockets

问题描述

我想使用套接字来发送bmp图像。我有这样code在Android：

I'm trying to send bmp image using socket. I have such code on android:

ByteArrayOutputStream stream = new ByteArrayOutputStream();
MainActivity.bmp.compress(Bitmap.CompressFormat.JPEG, 20,
                stream);
byte[] byteArray = stream.toByteArray();
OutputStream os = echoSocket.getOutputStream();
os.write(byteArray,0,byteArray.length);
os.flush();

在PC上：

InputStream in_ = clientSocket.getInputStream();
OutputStream out_ = new FileOutputStream("filename.bmp");
final byte[] buffer = new byte[1024];
int read = -1;
int i = 0;
while ((read = in_.read(buffer)) != -1) {
out_.write(buffer, 0, read); 
System.out.println(i);
i++;

}

in_.close();
out_.close();


System.out.println("Done");

它永远不会获取最后一行（的println（完成））。它只做当我关闭Android程序，它获取到最后一行和BMP成功地打开。问题是in_.read等待Android已经发送完毕后，我不能使它工作。

It never gets to last line( println("Done") ). It only does when I close android program, it gets to last line and bmp opens succesfully. problem is in_.read waits after android has finished transmitting, and i can't make it work.

推荐答案

您永远关闭在设备端的插座/的OutputStream所以PC端不知道有没有更多的数据，所以它只是旋转的同时，循环读取0字节一次。

You never close the socket/OutputStream on the device side so the PC side doesn't know that there is no more data and so it just spins in the while loop reading 0 bytes at a time.
