【问题描述】：
我是 android 开发的新手，遇到这个问题我的客户希望仅使用 LAN 连接将视频文件从他的相机存储流式传输到他的 android 手机。这可能吗？现在我唯一能做的就是从手机存储中播放视频并流式传输 http 或 RTSP 流式传输视频，但是是否可以在通过 LAN 发送视频文件时流式传输视频文件？谢谢。
@Androider-我很抱歉没有发表评论，因为我现在不能这是我的代码，任何形式的帮助都将不胜感激，谢谢。 编辑：
客户端
` 公共类客户端扩展了 Activi ty {
private Socket client;
private FileInputStream fileInputStream;
private BufferedInputStream bufferedInputStream;
private OutputStream outputStream;
private Button button;
private TextView text;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
button = (Button) findViewById(R.id.button1);
text = (TextView) findViewById(R.id.textView1);
//Button press event listener
button.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
File file = new File("/storage/emulated/BaseAhri.jpg");
try {
client = new Socket("10.0.2.2", 4444);
byte[] mybytearray = new byte[(int) file.length()];
fileInputStream = new FileInputStream(file);
bufferedInputStream = new BufferedInputStream(fileInputStream);
bufferedInputStream.read(mybytearray, 0, mybytearray.length);
outputStream = client.getOutputStream();
outputStream.write(mybytearray, 0, mybytearray.length);
outputStream.flush();
bufferedInputStream.close();
outputStream.close();
client.close();
text.setText("File Sent");
} catch (UnknownHostException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
服务器端
private static ServerSocket serverSocket;
private static Socket clientSocket;
private static InputStream inputStream;
private static FileOutputStream fileOutputStream;
private static BufferedOutputStream bufferedOutputStream;
private static int filesize = 10000000;
private static int bytesRead;
private static int current = 0;
public static void main(String[] args) throws IOException {
serverSocket = new ServerSocket(4444);
System.out.println("Server started. Listening to the port 4444");
clientSocket = serverSocket.accept();
byte[] mybytearray = new byte[filesize];
inputStream = clientSocket.getInputStream();
fileOutputStream = new FileOutputStream("/sdcard/DCIM/Camera/BaseAhri.jpg");
bufferedOutputStream = new BufferedOutputStream(fileOutputStream);});
System.out.println("Receiving...");
bytesRead = inputStream.read(mybytearray, 0, mybytearray.length);
current = bytesRead;
do {
bytesRead = inputStream.read(mybytearray, current, (mybytearray.length - current));
if (bytesRead >= 0) {
current += bytesRead;
}
} while (bytesRead > -1);
bufferedOutputStream.write(mybytearray, 0, current);
bufferedOutputStream.flush();
bufferedOutputStream.close();
inputStream.close();
clientSocket.close();
serverSocket.close();
System.out.println("Sever recieved the file");
}
错误服务器端
[2014-01-22 15:20:15 - AndroidSocketSERVER] ActivityManager: 开始: Intent { act=android.intent.action.MAIN cat=[android.intent.category.LAUNCHER] cmp=com.javacodegeeks.android .androidsocketserver/.Server }
[2014-01-22 15:20:15 - AndroidSocketSERVER] ActivityManager：错误类型 3

在我发送后它在客户端崩溃。不确定这是否是一个错误，因为我的服务器有问题....
@Androider - 抱歉更新晚了，这是我的结果代码，我现在可以传递视频文件并按位控制它，但问题是我的数据总是因为缺少字节或类似的东西而损坏现在我该如何流式传输？我无法播放该文件，因为它不完整？如果是这样，那么字节控制的目的是什么？我希望你能再次帮助我谢谢。
代码客户端和服务器：
serverTransmitButton = (Button) findViewById(R.id.button_TCP_server);
serverTransmitButton.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
Log.i("Start Server Button Clicked", "yipee");
try {
// create socket
// TODO: the port should match the one in Client
ServerSocket servsock = new ServerSocket(5005);
while (true) {
Log.i("************", "Waiting...");
Socket sock = servsock.accept(); // blocks until connection opened
Log.i("************", "Accepted connection : " + sock);
// sendfile
// TODO: put the source of the file
int filesize=8192;
File myFile = new File ("/sdcard/DCIM/Camera/test.mp4");
byte [] mybytearray = new byte [filesize];
Log.i("####### file length = ", String.valueOf(myFile.length()) );
FileInputStream fis = new FileInputStream(myFile);
BufferedInputStream bis = new BufferedInputStream(fis);
bis.read(mybytearray,0,mybytearray.length);
OutputStream os = sock.getOutputStream();
Log.i("************", "Sending...");
int read;
while((read = fis.read(mybytearray)) != -1){
os.write(mybytearray,0,read);
}
os.flush();
os.close();
fis.close();
bis.close();
}
} catch (IOException e) {
