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
