所以我在我的Android应用程序中有这个非常奇怪的错误。我正在尝试连接到TCP服务器,交换一些消息,真的没什么复杂的。我已经设法超越了它在开始时遇到的所有问题,但是现在我遇到了一个我希望有人知道如何修复的bug。
我连接到服务器并成功获取输入和输出流,但是当从服务器读取响应时,程序冻结。我研究了这个,我知道这是因为服务器没有消息。但我也知道服务器响应,因为我为iOS制作了相同的应用程序,它收到的一切都没问题。可以是一些Android问题吗?或者只是系统中的一些设置?
这是一段代码,告诉你这不是什么大问题。我在代码中没有更多东西,但是如果你需要查看剩下的内容,请询问。
提前致谢!
try {
InetAddress serverAddr = InetAddress.getByName(serverIP);
tcpSocket = new Socket(serverAddr, serverPort);
Log.e("socket",
"created socket with " + serverIP
+ Integer.toString(serverPort));
out = new PrintWriter(new BufferedWriter(
new OutputStreamWriter(tcpSocket.getOutputStream())),
true);
Log.e("socket", "output stream created alright");
in = new BufferedReader(new InputStreamReader(
tcpSocket.getInputStream()));
Log.e("socket", "input stream created alright");
out.println("handheld#" + clientID + "#connection request");
fromServer = in.read();
while(fromServer != -1) {
fromServer = in.read(); //updated, still no good
}
connected = true;
Log.e("socket", "connect thread will finnish");
} catch (UnknownHostException e) {
Log.e("socket", "error finding host", e);
} catch (IOException e) {
Log.e("socket", "error creating socket's streams", e);
}
答案 0 :(得分:0)
希望以下代码正常工作
InputStream in = tcpSocket.getInputStream();
if(in == null)
return null;
Log.e("socket", "input stream created alright");
out.println("handheld#" + "1111" + "#connection request");
byte[] buff = new byte[1024];
int read = -1;
long totalRead = 0;
while ((read = in.read(buff)) > 0)
{
out.write(buff, 0, read);
Log.i("readed Byte ", new String(buff));
totalRead += read;
if (totalRead % 100 * 1024 == 0)
{
System.out.printf("%d bytes read\n", totalRead);
}
}
我在我的示例中实现了从输入流成功读取的内容。
