I'm building a KivyMD python app for Android. I try to access the DeepL API. It works perfectly on my desktop and on my android device (when compiled with buildozer) when I use 'requests'. But it works on my desktop but not on my android device when I use the 'deepl' library instead of 'requests'. I want to use the 'deepl' library because the translations are better than when I use the 'requests' library.
My android device is Xiaomi Mi 9T
MIUI version : MIUI Global 12.0.5 Stable 12.0.5.0(QFJEUXM)
Android version : 10 QKQ1.190825.002
I'm using :
kivy 2.1.0
kivymd 1.1.1
deepl 1.14.0
Here is my code :

When building the app on my android device, it asks me if I'm OK to give access to my storage and I say yes.
Also, my MDFileManager is not opening on my android device but is on my desktop. Maybe the problem is related ?
Here is the code for my MDFileManager in my class FlasholatorApp(MDApp):
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
When I try to open my MDFileManager by clicking on a button, it doesn't crash but doesn't do anything.
Does anyone knows what is really causing the problem ?
Also, based on this post : https://stackoverflow.com/questions/64849485/why-is-filemanager-not-working-on-android-kivymd
I changed the self.device_root_path of my MDFileManager to self.primary_ext_storage.
self.primary_ext_storage is defined as this :
from android.storage import primary_external_storage_path
self.primary_ext_storage = os.environ['HOME'] if platform!='android' else primary_external_storage_path()
But that doesn't change anything. When I try to open my MDFileManager by clicking on a button, it doesn't crash but doesn't do anything.
Thank you
The library is trying to figure out which platform is running on, which causes the issue you observed (platform.platform() is throwing). Changing the way you instantiate your deepl.Translator should fix the issue.
From
self.translator = deepl.Translator(self.auth_key)
to
self.translator = deepl.Translator(self.auth_key, send_platform_info=False)
