White Screen when building an apk #2358

Closed NooRMaseR closed 4 months ago

NooRMaseR commented 4 months ago

a White screen when building an apk it works fine with this code

import flet as ft

class MainUI(ft.UserControl):
    def __init__(self) -> None:
        super().__init__()

    def build(self) -> ft.Row:
        self.textBox: ft.TextField = ft.TextField(hint_text="Ask....", width=250)
        self.msgs_sended: ft.Column = ft.Column()
        return ft.Row(
            alignment=ft.MainAxisAlignment.CENTER,
            controls=[
                ft.Column(
                    controls=[
                        ft.Text("MaseR Assistant"),
                        self.textBox,
                        ft.ElevatedButton(
                            "Send",
                            # on_click=self.send_msg
                        ),
                        self.msgs_sended,
                    ]
                )
            ],
        )

def main(page: ft.Page):
    page.title = "MaseR Assistant"
    page.add(ft.SafeArea(MainUI()))
    page.update()

ft.app(main)

and the app works perfectly

but when i create a class to do a Task in external file, i Get A white screen on android like there's no any widgets in the app these are the requirements

flet
textblob
googletrans

i even tried to add this class in the same main.py file i get the same white screen and this is the command i use flet build apk --description "MaseR Assistant AI Like Google Assistant" --org "com.noormaser" --build-version "0.0.2" --project "MaseR Assistant" -vv

This is how it looks

Could you please elaborate on what do you mean by "create a class to do a Task in external file"?

NooRMaseR commented 4 months ago

Could you please elaborate on what do you mean by "create a class to do a Task in external file"?

like having a separate file containing a class to do something

code2

FeodorFitsner commented 4 months ago

OK, how do you import that class in main.py?

NooRMaseR commented 4 months ago

OK, how do you import that class in main.py?

i import it like this

from botResponse import MaseR_Response

and below i use a function

def send_msg(self, _) -> None:
        question = self.textBox.value
        self.textBox.value = ""
        answer = MaseR_Response(question)
        self.msgs_sended.controls.append(ft.Text(f"{answer}"))
        self.textBox.update()
        self.msgs_sended.update()
FeodorFitsner commented 4 months ago

OK, try importing it as:

import botResponse

and then use as:

answer = botResponse.MaseR_Response(question)

Let me know if that worked in APK.

Would you be able to create a simple repro project in a public GitHub repository, so I can test with it?

Yes it works perfectly but when i build an apk, i get no widgets, like white Screen

taaaf11 commented 4 months ago

I am building apk on my side... Let's see what happens

taaaf11 commented 4 months ago

@NooRMaseR Unforunately, it's not working...

taaaf11 commented 4 months ago

@NooRMaseR Try adding self.update() to the MainUI class in send_msg function...

NooRMaseR commented 4 months ago

@NooRMaseR Try adding self.update() to the MainUI class in send_msg function...

I can not add self.update to the MainUI class because there's nothing to update yet, i have to return the UI and then update, but i can not update after the return keyword

taaaf11 commented 4 months ago

@NooRMaseR I asked to self.update() in send_msg function, not in build function

NooRMaseR commented 4 months ago

@taaaf11 sorry I read it wrong and it's still not working, and the the function is not even called yet to do an effect until the button clicked

taaaf11 commented 4 months ago

@NooRMaseR oh sorry. Please give us the output of flet build apk -vv

@NooRMaseR Sorry, I can't tell anything here... Maybe @FeodorFitsner helps...

NooRMaseR commented 4 months ago

@taaaf11 @FeodorFitsner i think i found the reason for the issue here, it's the textblob module, when i add textblob in my app i get no widgets on Android and when i remove the module the app works, i don't know why, besides googletrans module doesn't work as well, in my view i guess the app doesn't allow me to do online things on Android I don't know about other platforms but in windows works perfectly

taaaf11 commented 4 months ago

@NooRMaseR try adding the versions of the python packages you are using, just a suggestion.

Okay, this numpy package part worries me, @FeodorFitsner

FeodorFitsner commented 4 months ago

yep, numpy is the culprit. Should be built separately: https://pub.dev/packages/serious_python#android There is an issue to automate this: https://github.com/flet-dev/serious-python/issues/61

NooRMaseR commented 4 months ago

ok i will try this

@taaaf11 @FeodorFitsner i ran p4a create --requirements numpy --arch arm64-v8a --arch armeabi-v7a --arch x86_64 --sdk-dir $ANDROID_SDK_ROOT --ndk-dir $ANDROID_SDK_ROOT/ndk/$NDK_VERSION --dist-name serious_python in the terminal and i get this error

Run it on WSL: https://github.com/kivy/python-for-android/issues/2321#issuecomment-698667595

I had this issue once, it turned out to be the requirements.txt that was missing a required library, for me it was the webcolors library. Try searching for any missing libraries in the requirements.txt file.

Nothing is missing it's just numpy as they say, most of my modules uses numpy to analyze the input

Try building the apk on a VM, I usually setup a GitHub codespace or Google compute engine, if am having issues on my PC.

Not gonna lie but I'm done with such errors so i have created a web service using flask as API to get what I want exactly with high quality
