[Question] Open or share file (csv) on android

[OE3JGW]

Question

Hey guys,

im trying since days to implement a solution to export and then with a button in a snackbar open or share (prefered) a csv file im saving with my app on android using flet.
i tried different solution but none are working for me on android, windows is working perfectly.

Global variables for database paths

DATABASE_FILENAME = "antenna_tester.db"
if platform.system() == "Linux" and "ANDROID_STORAGE" in os.environ:
    DATABASE_PATH = "/data/data/com.flet.meshtenna/files"
else:
    DATABASE_PATH = os.path.expanduser("~/Documents")

if not os.path.exists(DATABASE_PATH):
    os.makedirs(DATABASE_PATH)

DATABASE_FILEPATH = os.path.join(DATABASE_PATH, DATABASE_FILENAME)
DESTINATION_NODE_ID = None

i tried this:

    def open_folder_or_file_picker(page):
        if platform.system() == "Windows":
            webbrowser.open(DATABASE_PATH)
        elif platform.system() == "Linux" and "ANDROID_STORAGE" in os.environ:
            # Android-specific FilePicker for selecting the export directory
            file_path = os.path.join(DATABASE_PATH, "exported_results.csv")
            if os.path.exists(file_path):
                page.launch_url(f"file://{file_path}")
            else:
                page.snack_bar = ft.SnackBar(
                    content=ft.Text("File does not exist."),
                    open=True,
                )
                page.update()

this:

    def open_folder_or_file_picker(page):
        if platform.system() == "Windows":
            webbrowser.open(DATABASE_PATH)
        elif platform.system() == "Linux" and "ANDROID_STORAGE" in os.environ:
            # Android-specific FilePicker for selecting the export directory
            file_picker = ft.FilePicker(on_result=lambda e: on_file_picker_result(e, page))
            page.overlay.append(file_picker)
            file_picker.get_directory_path()
            page.update()

and i think a few other solutions like "page.share_file(EXPORT_CSV_FILE)" aswell over the last week.
im new and really a beginner and try to make my way trough it.. but i would appreciate some help :/
what am i doing wrong?
