The app isn't responding

[ccinsz]

There is a problem, the app isn't responding.

When popup this dialog, it raises like this:
Thread[6,tid=15205,WaitingInMainSignalCatcherLoop,Thread*=0xb400007788b12dd0,peer=0x12c401a0,"Signal Catcher"]: reacting to signal 3

How can I solve this problem?

It is impossible for us to provide any advice without detailed reproduction instructions. We don't know what "this dialog" is, or anything else about the app you're currently writing.

the code of app.py as follows:

import time
import httpx
import toga
from toga.style import Pack
from toga.style.pack import COLUMN

class demo0529(toga.App):

def startup(self):
    main_box = toga.Box(style=Pack(direction=COLUMN))
    main_box.add(toga.Button('Button', on_press=self.mytest))

    self.main_window = toga.MainWindow(title=self.formal_name)
    self.main_window.content = main_box
    self.main_window.show()

def mytest(self, button):
    for i in range(10):
        with httpx.Client() as client:
            client.post("http://127.0.0.1:7912/session/com.android.settings")
        time.sleep(2)

def main():
return demo0529()

The app is reporting that it isn't responding because you're blocking the app's event loop.

This issue, and the fix, is discussed in step 8 of the BeeWare tutorial.
