ft.dropdown.Option content doesn't work as expected on Android #3616

Describe the bug

When I create a ft.Dropdown with a ft.dropdown.Option with the attribute content= in my page, it doesn't work on Android.

Code sample

Here is my `test.py` script: ```python import flet as ft def main(page: ft.Page): def button_clicked(e): t.value = f"Dropdown value is: {dd.value}" page.update() t = ft.Text() b = ft.ElevatedButton(text="Submit", on_click=button_clicked) dd = ft.Dropdown( width=100, options=[ ft.dropdown.Option(text="r", content=ft.Text("Red")), ft.dropdown.Option(text="g", content=ft.Text("Green")), ft.dropdown.Option(text="b", content=ft.Text("Blue")), ], ) page.add(dd, b, t) ft.app(target=main) ``` Here is the command line I used to create the APK file: ``` flet build apk --module-name test.py ```

To reproduce

  1. Create a file test.py with the previous content.
  2. Create an APK for Android plateform.
  3. Install on an Android device.
  4. Launch the app.

Expected behavior

When I run this code in Windows, it shows a dropdown with 3 choices ("Red", "Green", "Blue"). If I select one and submit, I see the key value in the page ("r", g" or "b").

I expect the same in Android.

Screenshots / Videos

Screenshots Result on Windows: ![image](https://github.com/flet-dev/flet/assets/13345603/266aecbc-6d38-4669-90e9-83272595dd33) Result on Android: Black empty screen.

Operating System

Windows

Operating system details

Windows 11 / Android 13

Flet version

0.23.2

Regression

I'm not sure / I don't know

Suggestions

I don't know how to view Python logs on the Android device. I suppose an exception occurs, because when I add debug traces, I don't see any after the creation of the ft.dropdown.Option element.

If I don't use content=ft.Text("..."), it works.

Logs

Logs How can I trace the logs in an Android device?

Additional details

If I run the application with flet run --android, it works as expected.

Have you looked at the CATlog data to understand what's going on.

Have you looked at the CATlog data to understand what's going on.

What is it? My main problem is that I don't know where to find the error log on an Android device.

EDIT: I found the "adb logcat" command, but nothing is obvious in this log. I've updated my initial post with the log.

Option.content was introduced in 0.23.0, if not mistaken, so normally everything should work as expected if you are really making use of a version post-0.23.0. I gave it a try and it worked:

@burhansvural , I can't see your video ("can't be played, file is corrupted").

Could you be more specific? Do you mean that I can't create an APK without p4a whereas I don't have any specific packages? Or that I have to use Python 3.11.6, not 3.11.9? Or Python 3.12?

EDIT: Python 3.12.4 -> also KO.

burhansvural commented 4 months ago

I'm use python 3.11 and 3.12 all packages, java= temurin-8.jdk, ndk=25.2.9519653 and API 33, cython=cython-3.0.10. I followed what was written on the page, respectively. I just used the "flet build apk" command.

PhunkyBob commented 4 months ago

@burhansvural what is your OS? I'm on Windows 11. How can you use temurin-8.jdk? When I use a version lower than 17, I have an error message saying that Gradle needs Java 17 at least.

PhunkyBob commented 4 months ago

OK, after a lots of tries and fails with several JDK (Temurin jdk8u412-b08, jdk-11.0.23+9, jdk-17.0.11+9, jdk-21.0.3+9), several NDK, and several computers (my personal and my professional computer), I'm giving up.

Since the rest of the application works as expected with my initial configuration, I'll avoid to use this component.
