KivyMD : MDFileManager not loading - android

I am trying to access a folder path using MDFileManager in kivymd. I am able to open it using the kivy launcher on the system but when packaged for android, the method call self.fileM.show(path) returns nothing and clicking multiple times gives ReferenceError: weakly-referenced object no longer exists.
Appreciate the help.
note: presenting only a snippet from the original code for the question.

# List as sections
#
# You can define all the "list" as [section:key].

# Let's take [app] / source.exclude_patterns.
# Instead of doing:
#
#[app]
#source.exclude_patterns = license,data/audio/*.wav,data/images/original/*
#
# This can be translated into:
#
#[app:source.exclude_patterns]
#license
#data/audio/*.wav
#data/images/original/*
#
# -----------------------------------------------------------------------------
# Profiles
#
# You can extend section / key with a profile
# For example, you want to deploy a demo version of your application without
# HD content. You could first change the title to add "(demo)" in the name
# and extend the excluded directories to remove the HD content.
#
#[app#demo]
#title = My Application (demo)
#
#[app:source.exclude_patterns#demo]
#images/hd/*
#
# Then, invoke the command line with the "demo" profile:
#
#buildozer --profile demo android debug

Try doing this for de path.
import os
app_path = os.path.dirname(os.path.abspath(__file__))
May is some kind of error in the path, try it like above and debug from there.

Try this code below,
request_permissions([Permission.READ_EXTERNAL_STORAGE, Permission.WRITE_EXTERNAL_STORAGE])
dir_primary = primary_external_storage_path()
self.path = os.path.join(dir_primary, 'Download')

You basically need storage permission to access the internal storage in Android. To do so you can use this code snippet
if platform == 'android':
import android
from android.permissions import request_permissions, Permission
request_permissions([Permission.WRITE_EXTERNAL_STORAGE, Permission.READ_EXTERNAL_STORAGE])
Also, you have to add Android in your requirements of buildozer.spec file. Now to access the path of 'Downloads folder' you can use os.path.join(os.getenv('EXTERNAL_STORAGE'), 'Downloads')
def openfile(self,obj):
path = os.path.join(os.getenv('EXTERNAL_STORAGE'), 'Downloads')
self.fileM = MDFileManager(
select_path = self.get_path
)
self.fileM.show(path)
There's also a primary_external_storage_path() option in Android but it sometimes gives error in few versions of android
from android.storage import primary_external_storage_path
ext_path = primary_external_storage_path()
def openfile(self,obj):
path = os.path.join(ext_path,'Downloads')
self.fileM = MDFileManager(
select_path = self.get_path
)
self.fileM.show(path)
You can use any of these two methods. Also if the code snippet (for permissions) gives an error (app crashes after requesting permissions or crash at the start) then you might have to update your kivy version. In requirements of your buildozer.spec file instead of writing Python,kivy you can write Python,kivy=2.0.0rc4 so that it uses the latest version

Kivy Camera Android App compiled using Buildozer crashes on startup

I recently built my python file into an APK file, however the app crashes immediately after opening it. The application is just a camera interface using OpenCV, Kivy and KivyMD. I already included the necessary libraries that should be indicated in the buildozer.spec file and also the permissions. I don't know why it is crashing and badly need some help.
Here's my code:
main.py:
from kivymd.app import MDApp
from kivymd.uix.boxlayout import MDBoxLayout
from kivymd.uix.button import MDRaisedButton
from kivy.uix.image import Image

class MainApp(MDApp):
faceCascade = cv2.CascadeClassifier('haarcascade_frontalface_alt2.xml')
def build(self):
layout = MDBoxLayout(orientation='vertical')
self.image = Image()
layout.add_widget(self.image)
layout.add_widget(MDRaisedButton(
text="CLICK HERE",
pos_hint={'center_x': .5, 'center_y': .5},
size_hint=(None, None))
)
self.capture = cv2.VideoCapture(1)
Clock.schedule_interval(self.load_video, 1.0/33.0)
return layout
def load_video(self, *args):
ret, frame = self.capture.read()
gray = cv2.cvtColor(frame, cv2.COLOR_BGR2GRAY)
faces = self.faceCascade.detectMultiScale(gray,
scaleFactor=1.1,
minNeighbors=5,
minSize=(60, 60),
flags=cv2.CASCADE_SCALE_IMAGE)
for (x,y,w,h) in faces:
cv2.rectangle(frame, (x, y), (x + w, y + h),(0,255,0), 2)
faceROI = gray[y:y+h,x:x+w]
buffer = cv2.flip(frame, 0).tostring()
texture = Texture.create(size=(frame.shape[1], frame.shape[0]), colorfmt='bgr')
texture.blit_buffer(buffer, colorfmt='bgr', bufferfmt='ubyte')

I couldn't paste my logcat here due to having of multiple number of lines, but here's a link (site similar to pastebin) for it.
I think giving permission from the app info of the app works !

Auto selection of Text in TextInput and BackSpace problem in KIVY

My code is works fine on PC but when converted into APK file i get problem with the use of Auto selection of text in TextInput and backspace on Android
As simple my problem in Android APK is that
" When i starting to type "Hello" and after completing a word i uses space bar then the following text is ADDED to the the TextInput field and changes to "HelloHello", as well correct to edit back the that word uses BackSpace which is not worked very well.
I never have this on the PC, but always on Android.
As i am using KIVY version 2.0.0 and MDKIVY version 0.104.2

Partially i have go trough the github following link https://github.com/kivy/python-for-android/issues/2461 , in this person facing same problem as I and there is small video which is exactly matches with my problem, but i don't understand the solution of that.
Thank You so much.

Android APK crashing (kivymd)

I´m currently coding an android App using kivymd in python. My Problem is, that it crashed if I download the App on my Phone. I reduced my code to a minimum of lines to find the issue and ended up with these:
from kivy.uix.gridlayout import GridLayout
from kivy.lang.builder import Builder
#from kivy.app import App
from kivymd.app import MDApp
kv = '''
GridLayout:
cols: 1
MDToolbar:
title: "Menu"
Button:
text: "test"
'''
class MyApp(MDApp):
def build(self):
return Builder.load_string(kv)
if __name__ == "__main__":
MyApp().run()
I used the buildozer on google collab to deploy it to APK:

I already tried it with this code (without any kivyMD feature) and it worked:
from kivy.uix.gridlayout import GridLayout
from kivy.lang.builder import Builder
#from kivy.app import App
from kivymd.app import MDApp
kv = '''
GridLayout:
cols: 1
Button:
text: "test"
'''
class MyApp(MDApp):
def build(self):
return Builder.load_string(kv)
if __name__ == "__main__":
MyApp().run()
Thank you in advance!
I´ve found the mistake: since the last update for kivymd you have to add "pillow" to the requirements

things i tried:-
reinstalling cryptography,
using an older verison of cryptography,
cleaning buildozer with buildozer android clean,
using this command sudo apt install build-essential libltdl-dev libffi-dev libssl-dev python-dev
i still don't know what the problem is, but reinstalling Linux OS entirely fixed my problem.

Your your app runs fine on Acer Iconia Tablet. The only problem is that after taking the picture, it did not show the picture in the Kivy App.
I am using the following versions to create the apk file:
Buildozer v0.39
Cython 0.28.6
Python 3.6.7
Xubuntu 18.04 Bionic Beaver
