DeepL API和MDFileManager无法在KivyMD 1.1.1 android应用程序上运行

    我正在为Android构建一个KivyMD python应用程序。我尝试访问DeepL API。当我使用“requests”时,它在我的桌面和android设备上(当使用buildozer编译时)都能完美工作。但当我使用“deepl”库而不是“requests”时,它在我的桌面上有效,但在我的android设备上无效。我想使用“deepl”库,因为翻译比使用“requests”库时更好。

    我的安卓设备是小米小米9T

    MIUI版本:MIUI Global 12.0.5稳定版12.0.5.0(QFJEUXM)

    安卓版本:10 QKQ1.190825.002

    我正在使用:

    基维2.1.0

    基维姆德1.1.1

    深度1.14.0

    这是我的代码:

    以下是我的buildozer.spec文件权限:

    android.permissions = WRITE_EXTERNAL_STORAGE, READ_EXTERNAL_STORAGE, INTERNET, SSL

    以下是我得到的错误:

    在我的android设备上构建应用程序时,它会问我是否可以访问我的存储,我说可以。

    此外,我的MDFileManager没有在我的android设备上打开,而是在我的桌面上。也许问题与此有关?

    以下是我所在班级FlasholatorApp(MDApp)中MDFileManager的代码: 

    class FlasholatorApp(MDApp):
    ...
    def open_save_database_folder_selector(self):
        def save_database(path):    
            print("Sauvegarde du paquet de carte ...")
            # Pass the file path to save_database() method
            self.flashcard_collection.save_database(path)
            print("Paquet de cartes sauvegardé avec succès !")

            # Close the file manager
            file_manager.close()

        # Create a file manager instance
        file_manager = MDFileManager(
            exit_manager=lambda x: file_manager.close(),
            select_path=save_database,
            ext=[".db"],
            selector="folder"
        )

        # Open the file manager
        file_manager.show(self.device_root_path) # Starting path

    当我试图通过单击按钮打开MDFileManager时,它不会崩溃,但不会执行任何操作。

    有人知道问题的真正原因吗?

    此外,基于此帖子: https://stackoverflow.com/questions/64849485/why-is-filemanager-not-working-on-android-kivymd

    我更改了 self.device_root_path 的MDFileManager到 self.primary_ext_storage 。

    自身主要外部存储 定义如下: 

    from android.storage import primary_external_storage_path
self.primary_ext_storage = os.environ['HOME'] if platform!='android' else primary_external_storage_path()

    但这并不能改变任何事情。当我试图通过单击按钮打开MDFileManager时,它不会崩溃,但不会执行任何操作。

    非常感谢。

    库正在试图弄清楚运行在哪个平台上,这导致了您观察到的问题( platform.platform() 正在投掷)。更改实例化您的 deepl.Translator 应该解决这个问题。

    从…起

    self.translator = deepl.Translator(self.auth_key)

    到

    self.translator = deepl.Translator(self.auth_key, send_platform_info=False)
