socket 服务端无法接收数据
本人写了一个项目，通过Socket用Android发出一个String，运行在本机上的服务端接受并写入文件中，但是客服端写不出数据，是在 os.write((bin.getText().toString()).getBytes("utf-8"));
这条代码卡住了，发不出数据，也无法执行后面代码，求大帮忙呀！
客户端
bu1.setOnClickListener(new OnClickListener()
{

public void onClick(View v) {
// TODO Auto-generated method stub
try{
s=new Socket("192.168.137.49",37000);
os=s.getOutputStream();
in=s.getInputStream();
os.write((bin.getText().toString()).getBytes("utf-8"));
bin.setText("");
}catch(Exception e){
e.printStackTrace();
}
}


});

服务端：
public class SimpleServer {
public static void main(String[]args)throws Exception
{
ServerSocket ss=new ServerSocket(37000);

while(true)
{
Socket s=ss.accept();

BufferedReader br=new BufferedReader(new InputStreamReader(s.getInputStream(),"utf-8"));
FileOutputStream fos = null;
BufferedWriter bw = null;
String content=br.readLine();

while((content!=null)&&(content.length()!=0))
{
System.out.println(content);
try {
File file = new File("d:\\ok.txt");
fos = new FileOutputStream(file);

bw = new BufferedWriter(new OutputStreamWriter(fos));
bw.write(content);

}catch (FileNotFoundException fnfe) {
fnfe.printStackTrace();
}
catch (IOException ioe){
ioe.printStackTrace();
}
finally {
try {
if (bw != null)
bw.close();
if (fos != null)
fos.close();
}catch (IOException ie) {

}
}
}
}
}

}

[解决办法]
os.write((bin.getText().toString()).getBytes("utf-8"));
后面加上
os.flush();
[解决办法]

  os.write((bin.getText().toString()).getBytes("utf-8"));

os.flush();
