jnius.jnius.JavaException: Class not found b'org/renpy/android/PythonActivity' when trying to use the takePicture function #520

Here is my code:

import SFTPServices
import os
from plyer import camera
import uuid
dir_path = os.path.dirname(os.path.realpath(__file__))
from kivy import platform
from kivy import app

def takePicture():
    result=''
    try:
        if platform == 'android':
            picName = f'{uuid.uuid4()}.jpg'
            picPath = os.path.join(app.App.get_running_app().user_data_dir, picName)
            print(f'Trying to take pic :{picPath}')
            camera.take_picture(filename=picPath, on_complete=sendPicture)
        else:
            print(f'Taking pic supported only in adnroid.current os:{platform}')
            result = f'Taking pic supported only in adnroid.current os:{platform}'
        return result

    except Exception as e:
        print(f'Error while taking pic :{str(e)}')
        return f'Error while taking pic :{str(e)}'

def sendPicture(path):
    try:
        if (os.path.exists(path)):
            print(f'Pic saved successfully to:{path}')
            SFTPServices.sendFile(path)
        else:
            print(f'image was not found at {path}')
    except Exception as e:
        print(f'Error while trying to send pic :{str(e)}')
        return f'Error while trying to send pic :{str(e)}'

Here is the Exception I am getting

#    List as sections
#
#    You can define all the "list" as [section:key].
#    Each line will be considered as a option to the list.
#    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

The problem is here. That class is unused, and also not recognized. By the way, PythonActivity is now at org.kivy.android (org.renpy.android is deprecated).

Thanks! But how i apply this fix on buildozer? it compiles the original version only

While it is not merged, you have to install my branch via pip. To do that, in you buildozer.spec, go to your requirements and replace plyer for git+https://github.com/Franccisco/plyer/archive/android-camera-bug-fix.zip Maybe you need to clean the .buildozer folder in your app's directory first. Try it and leave a comment in https://github.com/kivy/plyer/pull/525, please.

tomgold182 commented 4 years ago

Will keep you updated

tomgold182 commented 4 years ago

@Franccisco I managed to apply your fix but now another issue occurs: b"Exception in connect function: Class not found b'org/jnius/NativeInvocationHandler'" i will open a seperate issue for that

ShelleyLake commented 2 years ago

Interesting project, but... is there a damn example that uses CAMERA functionality that really works with Android 8?
