我用从服务器到我的Android应用程序通信问题,basiclly通信是这样的:为什么不读第二行?
1. send x and y
2. get the list of coordinates from server
3. send "ok"
4. receive titles string
一切进展顺利,直到最后一行,我知道这是正常发送,因为它通过telnet工作,但我的Android应用程序没有收到任何东西。下面是用于发送和接收客户端代码:
clientSocket = new Socket("10.0.2.2", 1234);
Log.d("LatitudeE6", ""+point.getLatitudeE6());
Log.d("LongitudeE6", ""+point.getLongitudeE6());
os = new PrintStream(clientSocket.getOutputStream());
is = new DataInputStream(clientSocket.getInputStream());
sentenceX = ""+point.getLatitudeE6();
sentenceY = ""+point.getLongitudeE6();
os.println(sentenceX + " "+ sentenceY+'\n');
String thing =is.readLine();
String [] holder = thing.split("\\s+");
System.out.println("thing printed: " +thing);
os.println("ok\n");
String test = is.readLine();
System.out.println("tester: " +test); // this doesn' work
服务器:
try{
in = new DataInputStream(clientSocket.getInputStream());
os = new PrintStream(clientSocket.getOutputStream());
ms.connector();
while(true){
line = in.readLine();
if(line.startsWith("51789181 19426953")==true){
// these are the coordinates, if the client sends them, it will receive the list of other coordinates
os.println(ms.lister().toString().replace('[', ' ').replace(']', ' ').trim().replace(',', ' ') +""+'\n');
os.flush();
}else if (line.equals("ok")==true) {
os.flush();
os.println(ms.topicDesc().toString().replace('[', ' ').replace(']', ' ').trim().replace(',', ' ') +""+'\n');
}
}
catch(IOException e){
e.printStackTrace();
}
您发送后确定换行,并刷新插座,在服务器端? –
我刚刚加入“\ n”后“确定”,并刷新插座,但它不会改变任何事情。 – iie
对不起,我miswrote我的评论之前 - 在另一边的标题字符串后,你发送一个换行符?请显示服务器代码。 –
