My app runs fine when executed in development mode on Windows.

Used packages out of the ordinary:

paho-mqtt
sseclient Both packages are pure Python as far as I understand.

I also use the Requests package for HTTP communication and the Json package.

I implemented a way to debug remotely (send messages over a socket to another machine for display at run-time). Code:

`# Code to handle sending print() messages over a socket to the remote terminal

terminal_server_ip = '172.16.254.133' terminal_server_port = 12345 send_msg_via_socket = True socket_initialized = False client_socket = None

import socket

def showStatusMsg(msg): global send_msg_via_socket, socket_initialized, client_socket, terminal_server_ip, terminal_server_port

if send_msg_via_socket == False:
    print(msg)
    return

# Send via socket
if socket_initialized == False:
    # Create a socket object
    client_socket = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
    # Connect to the server
    client_socket.connect((terminal_server_ip, terminal_server_port))
    print(f"Connected to server at {terminal_server_ip}:{terminal_server_port}")
    socket_initialized = True

client_socket.send(msg.encode())``

Using: Python 3.11.6 Flet 0.19.0 Flutter 3.16.5, Dart 3.2.3, DevTools 2.28.4 Windows 11

ISSUES:

On WINDOWS:

Why a Windows build generates so many files and not one executable? Is there a way to have it create one executable?
Following executing the generated Windows executable, I could not find the out.log logging file... where should I look for that?
Any solution for using my remote logging (over a socket) option? Code included above.

On ANDROID:

I generated the apk and installed to the phone using adb
Where can I find the out.log file in Android?
When the app launched, I received an error message (see attached two pictures from two runs). Looks like the executable has a problem working with sockets (I am using the Requests and paho-mqtt packages which as far as I know are pure Python). Please check this and fix as needed as it may be a major issue.

Please let me know if additional explanation is needed.

Thanks a lot for addressing these issues!

@mottibz i have the same issue here I'm using the requests module to get the response from my API and the app works perfectly on and it works only 1 time

Screenshot_2024-01-18-18-23-44-038_com.noormaser.maser_assistant.jpg

And when i close the app and open it again i get that error

Try close-ing the socket and deleting the socket object.

Can you guys give me a sample app to reproduce the issue? Or you are saying it's reproducible with any "hello world" app?

it works fine when the app starts in the first time on android, but the second time i get that error, so the app can work again i have to clear the app's data like to start the app fresh from the beginning

@taaaf11 Still not working, this is the code that i use

I didn't ask about that req object. Rather I asked about any of the socket (from module socket) you might be using. I think this issue resides in the internal of flet

i'm not using socket module, i use only requests module

mottibz commented 4 months ago

Can you guys give me a sample app to reproduce the issue? Or you are saying it's reproducible with any "hello world" app?

Hi @FeodorFitsner, it will be really hard to provide a sample app to generate the issue as it is embedded in multiple modules in my app. I suggest that you take the code I provided when opening the issue above (also provided below), put it into a simple Flet main.py with the main code calling showStatusMsg() a few times with a message to send. Below this code I also include the terminal server code that is supposed to capture the message on the remote machine and display it. I am proposing using this to test as both the Requests and paho-mqtt packages use sockets for communication so the below simple code, if it will run correctly on executables built for Android and Windows, should resolve the other communication issues.

terminal_server_ip = '' terminal_server_port = 12345 send_msg_via_socket = True socket_initialized = False client_socket = None

import socket

def showStatusMsg(msg): global send_msg_via_socket, socket_initialized, client_socket, terminal_server_ip, terminal_server_port

if send_msg_via_socket == False: print(msg) return

# Send via socket
if socket_initialized == False:
    # Create a socket object
    client_socket = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
    # Connect to the server
    client_socket.connect((terminal_server_ip, terminal_server_port))
    print(f"Connected to server at {terminal_server_ip}:{terminal_server_port}")
    socket_initialized = True

client_socket.send(msg.encode())``

TERMINAL SERVER CODE:

import socket

Server configuration

host = '' # Listen on all available interfaces port = 12345

Create a socket object

server_socket = socket.socket(socket.AF_INET, socket.SOCK_STREAM)

Bind the socket to a specific address and port

server_socket.bind((host, port))

Enable the server to accept connections

server_socket.listen(5)

print(f"Server listening on {host}:{port}")

Accept a connection from the client

client_socket, client_address = server_socket.accept() print(f"Connection established with {client_address}")

while True:

Receive data from the client

data = client_socket.recv(1024)
if not data:
    break
print(f"Received data: {data.decode()}")

Close the connection

client_socket.close() server_socket.close()

mottibz commented 4 months ago

Don't know why the terminal server code is formated in a strange way, reposting:

` import socket

Server configuration

host = '' port = 12345

Create a socket object

server_socket = socket.socket(socket.AF_INET, socket.SOCK_STREAM)

Bind the socket to a specific address and port

server_socket.bind((host, port))

Enable the server to accept connections

server_socket.listen(5)

print(f"Server listening on {host}:{port}")

Accept a connection from the client

client_socket, client_address = server_socket.accept() print(f"Connection established with {client_address}")

while True:

Receive data from the client

data = client_socket.recv(1024)
if not data:
    break
print(f"Received data: {data.decode()}")

Close the connection

client_socket.close() server_socket.close() `

mottibz commented 4 months ago

Not sure why it is formated like this... I used the code embedding option and it still breaks the format...

FeodorFitsner commented 4 months ago

Use three ticks to format the code.

mottibz commented 4 months ago

client.txt server.txt

I attached them as files. Please let me know if arrived correctly. Thanks a lot!

FeodorFitsner commented 4 months ago

where do you run server?

mottibz commented 4 months ago

The client is embedded in a Flet app as described above.
The server runs on another machine that is on the same network subnet as the client, as a simple Python app.
You first start the server and it listens on the port for incoming connection from the client
You then start the client app and it connects to the server and sends the messages you call the showStatusMsg() function to send.

mottibz commented 4 months ago

You need two PCs for this test.
At the top of the code of both, you need to insert the IP address of the server machine.

NooRMaseR commented 4 months ago

this is the repo for the source code of my app can someone check it please and tell me what is the problem on android ? https://github.com/NooRMaseR/error-test

NooRMaseR commented 4 months ago

it might take some time like 5 sec or something to get the response because i use a free plane

mottibz commented 4 months ago

Hi @NooRMaseR , As I wrote above, I beleive that the issue is enabling network communication and the code I provided uses the basic socket interface. If that will work correctly, than probably, higher level packages such as Requests (which uses sockets) will work.

NooRMaseR commented 4 months ago

Hi @mottibz , i think the problem is that the connection is still running in the background twice in my app's case, because the first time I opened the app, it works perfectly and when i close the app the app closes but the connection is still running, as @taaaf11 said i need to close the connection, even though i closed the connection already after i get the response and the connection is still running i don't know why, that's why when i clear the app's data, the app works again, like the connection is finally closed

mottibz commented 4 months ago

I am sure that @FeodorFitsner will solve this in no time :-)

FeodorFitsner commented 4 months ago

I've managed to reproduce "SocketException: Failed to create server socket (OS Error: File exists with given unix domain address), address = stdout.sock, port = 0" issue.

Working on the fix!

FeodorFitsner commented 4 months ago

Fixed the app template - the app is not crashing with that error anymore when restarted multiple times. Rebuild your APK with flet build apk to get updated template.

mottibz commented 4 months ago

Will test and let you know if OK. Thanks!

mottibz commented 4 months ago

Tried the apk quickly. A few comments:

First execution, stared and immediatly quitted
Another try, got an error that the application has a bug and I should allow cleaning the cache. I remember getting this error when running the Flet application that supports the development
Another run, got it half working (but no socket error). Looks like there is still some networking issues.

Can you please fix the socket communication issue that I reported (using the code I sent for the client and server)? Flet should have a way to enable debugging of a compiled app for both Android and Windows. I think that best will be to support the remote terminal as I have tried to do. Can this be done?

mottibz commented 4 months ago

Hi @FeodorFitsner , looks like my socket code now starting to wor. I will investigate it further and if this actually works, I will publish the code in an organized way so that developers can use it to debug their executables in an easy way. Think about running your Android executable on your phone and seeing the debug output from the Android app on your PC :-)

Hi @FeodorFitsner , thank you for solving the problem in my case, and it works good now, but there's 1 issue

First run works good
Second run the app closes suddenly
Third run the app works again
