Socket Python-Server 和 Java - android studio 中的客户端，其中 java 无法连接到 python 服务器
[英]Socket Python-Server and Java - Client in android studio where java is not able to connect to the python server
问题描述
I have successfully built a python server which even works but when java from android studio tries to connect to it fails with whole bunch of errors.
我已经成功构建了一个甚至可以工作的 python 服务器，但是当来自 android studio 的 java 尝试连接到它时失败并出现一大堆错误。 I have understood that it fails while creating a new socket object but why that I don't know.我知道它在创建新的套接字对象时失败，但我不知道为什么。
This is Java client, see at the end of the code particularly for the issue where I have created new Socket object:这是 Java 客户端，请参见代码末尾，特别是关于我创建新 Socket 对象的问题：

This is my python server code:这是我的python服务器代码：
import socket
s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
print("Socket successfully created")
try:
port = 24224
s.bind(("", port))
print("socket binded to %s" %(port))
except socket.error as err:
print('Bind failed. Error Code : ' .format(err))
s.listen(10)
while True:
conn, addr = s.accept()
print('Got connection from', addr)
message = conn.recv(1024)
print("Client : " + message)
conn.close()

Looking at the stack trace I see that you are trying to connect on the ui thread which is causing the crash.查看堆栈跟踪，我看到您正在尝试连接导致崩溃的 ui 线程。 You need to move the connection logic in to its own thread您需要将连接逻辑移动到它自己的线程中
Here is a link to the documentation that will help you https://developer.android.com/guide/components/processes-and-threads#Threads这是文档的链接，可以帮助您https://developer.android.com/guide/components/processes-and-threads#Threads
