Hey @AndreMiras did you find the resolution for this issue?

AndreMiras commented 5 years ago

Hey glad you're using the project. Well I saw this error in Sentry, but I could't reproduce myself back then. Are you able to reproduce this issue everytime and it's once in the while? Because if it's easy for you to reproduce then I can ping you once I've updated. What's your device and OS version by the way?

Anyway this project needs to be updated to recent python-for-android changes as well as to Python3. Also a lot of other deps in the Ethereum stack will need to be updated. I'll start working on this pretty soon and hopefully this error will vanish.

Hey, I am sorry, I am not using this project hehe. I was testing the camera on my project, and looks good on Linux, but when I tried to run it on Android, it failed, googling the error, bring me up to here

AndreMiras commented 5 years ago

Well that may still help to know which device you have. And also if you could share the stacktrace

I forgot to add the buildozer:

android.permissions = CAMERA
AndreMiras commented 5 years ago

OK in this case it could be a runtime permission problem. Look how it's being handled in zbarcam for instance https://github.com/kivy-garden/garden.zbarcam/blob/20190303/zbarcam/zbarcam.py#L73 If you need further help try on the Kivy support channel, you can ping me there directly

Yeah, you right, I am copying the code just for the next newbie like me :D

from kivy.app import App
from kivy.lang import Builder
from kivy.uix.boxlayout import BoxLayout
from kivy.utils import platform
import time

Builder.load_string('''
<CameraClick>:
    orientation: 'vertical'
    Camera:
        id: camera
        resolution: (640, 480)
        play: False
    ToggleButton:
        text: 'Play'
        on_press: camera.play = not camera.play
        size_hint_y: None
        height: '48dp'
    Button:
        text: 'Capture'
        size_hint_y: None
        height: '48dp'
        on_press: root.capture()
''')

class CameraClick(BoxLayout):
    def __init__(self, **kwargs):
        super().__init__(**kwargs)
        self._request_android_permissions()

    @staticmethod
    def is_android():
        return platform == 'android'

    def _request_android_permissions(self):
        """
        Requests CAMERA permission on Android.
        """
        if not self.is_android():
            return
        from android.permissions import request_permission, Permission
        request_permission(Permission.CAMERA)

    def capture(self):
        '''
        Function to capture the images and give them the names
        according to their captured time and date.
        '''
        camera = self.ids['camera']
        timestr = time.strftime("%Y%m%d_%H%M%S")
        camera.export_to_png("IMG_{}.png".format(timestr))
        print("Captured")

class TestCamera(App):

    def build(self):
        return CameraClick()

TestCamera().run()

is this fixed? can the kivy camera run on android @AndreMiras

AndreMiras commented 4 years ago

Yes @fengboZ the Kivy camera runs on Android. I use it for PyWallet and EtherollApp all through zbarcam

fengboZ commented 4 years ago

I copied the code above and compiled it to an apk files, but it crashed after opening it on android..., I am new to kivy, wanna build an android application using kivy.

These are what my application is supposed to do:

1: My application basically needs to read a file from the PC and store the data(not necessarily need to be stored in app, but the app have to bale to read it later during processing time) . This file can be named A.

2: Open up the camera and take a photo.

3: And then the photo needs to be processed using detection library which will return a text(B) back

4: This text(B) will be used as index to query File A and then get another text(C) . and then the text(C) will be stored on android, it needs to be later transferred into PC.

Questions: can I complete these procedures with kivy? (just to confirm, if it can be done in kivy, I'll spend time on kivy) thanks for you comments @AndreMiras

Hello, I tried using android runtime permissions, as suggested by @AndreMiras, but buildozer logcat returns the following error message:

 from virtualenv import main ImportError: cannot import name 'main'

Buildozer.spec : requirements: python3, kivy, pyjnius android.add_aars = support-compat-27.0.0.aar

main.py

from kivy.app import App from kivy.uix.boxlayout import BoxLayout from permissions.location import check_permission, ask_permission

class ExampleRoot(BoxLayout):

def check_fine_location_permission(self):
    check_permission("android.permission.ACCESS_FINE_LOCATION")

def request_fine_location_permission(self):
    ask_permission("android.permission.ACCESS_FINE_LOCATION")

class ExampleApp(App): def build(self): return ExampleRoot()

if name == 'main': ExampleApp().run()

permissions/location.py

from jnius import autoclass from kivy.logger import Logger

PythonActivity = autoclass("org.kivy.android.PythonActivity").mActivity Context = autoclass('android.content.Context') ContextCompat = autoclass('android.support.v4.content.ContextCompat')

def check_permission(permission, activity=PythonActivity): permission_status = ContextCompat.checkSelfPermission(activity, permission)

Logger.info(permission_status)
permission_granted = 0 == permission_status
Logger.info("Permission Status: {}".format(permission_granted))
return permission_granted

def ask_permission(permission, activity=PythonActivity): PythonActivity.requestPermissions([permission])

Any suggestion to fix this error?

Thanks a lot

Sim @fengboZ, a câmera Kivy é executada no Android. Eu o uso para PyWallet e EtherollApp durante todo o zbarcam

Hi @AndreMiras, what's Kivy and buildozer versions used to generate the apk file of zabarcam?

AndreMiras commented 4 years ago

It was probably the latest version back then. Also zbarcam (upstream) CI itself was using a specific version https://github.com/kivy-garden/zbarcam/blob/2019.1020/dockerfiles/Dockerfile-android#L20. But I'll probably update both projects in the coming days so keep an eye on both repositories. Also both projects will have their CI updated and will be submitted to F-Droid so you can study the reproducibility of the builds. I'm closing this issue as it's old and being dragged in a different direction.

Hello everyone, I hope you can help me. I have the same problem JavaException: JVM exception occurred: Fail to connect to camera service. I see that the possible solution is to use android.permission. How can I install this library? Thank you so much

RobertFlatt commented 1 year ago

The android package is pre-installed in the generated apk/aab. It is not available on other platforms https://github.com/Android-for-Python/Android-for-Python-Users#the-android-package

The above posts are kinda old when measured in 'computer years'. A couple of general points:

1) The runtime permissions code above must, on newer Android devices, be called after on_start() https://github.com/Android-for-Python/Android-for-Python-Users#user-permissions

2) Kivy Camera (and it's derivatives such as zbarcam) use a depreciated Android api. As an alternative consider https://github.com/Android-for-Python/Camera4Kivy there are some examples https://github.com/Android-for-Python/Camera4Kivy#examples

Support requests should be directed to the user groups https://discord.gg/NzawVYMe or https://groups.google.com/g/kivy-users

roysomoza commented 1 year ago

Thank you very much for the immediate response, I am currently using a device with OS 8.0, I thought that the solutions in that post could help. I will study the options you have given me and join the Discord group.

If you allow me, I will write to you by this means in case I have any other questions. I appreciate a lot your help

Best to ask in the user groups, asking me questions directly assumes I know the answer. And pretty much everything I know with any confidence is in the document I linked.
