plyer: Error in access camera android.

I’am trying execute this:

from kivy.app import App 
from kivy.uix.boxlayout import BoxLayout
from kivy.lang import Builder

from plyer import camera

import time

Builder.load_string('''
<CameraScreen>:
	orientation: 'vertical'
	Image:
		id: image
	Button:
		size_hint_y: None
		height: '100dp'
		text: "Acess Camera"
		on_release: root.acess_camera()

''')

class CameraScreen(BoxLayout):
	
	def acess_camera(self):
		name_photo = time.strftime("%d%Y_%H%M%S") + ".jpg"
		print(name_photo)
		camera.take_picture(filename=name_photo, on_complete=self.camera_callback)

	def camera_callback(self, filename):
		print("filename: ", filename)
		self.ids.image.source = filename

class CameraApp(App):
	def build(self):
		return CameraScreen()

CameraApp().run()

But, I’m getting this error:

jnius.jnius.JavaException:` JVM exception occurred: file://212019_193209.jpg exposed beyond app through `ClipData.Item.getUri()

Any idea for resolve it?

I can use camera in android API 27.

Add this file in your project folder. I created a folder named libs.
In buildozer.spec file I change these lines: Permissions: android.permissions = INTERNET, ACCESS_FINE_LOCATION, WRITE_EXTERNAL_STORAGE, CAMERA Add path to FileProvider lib: android.add_aars = ./libs/support-v4-24.1.1.aar
Add this file too , it is based in plyer module.
Build your project: buildozer android debug
After builded, in the .buildozer\android\platform\python-for-android\pythonforandroid\bootstraps\sdl2\build\templates\AndroidManifest.tmpl.xml file add the following code snippets:

...
<!-- Android 2.3.3 -->
<uses-sdk  android:minSdkVersion="{{ args.min_sdk_version }}"  android:targetSdkVersion="{{ android_api }}"  />

+ <uses-feature  android:name="android.hardware.camera"  />
+ <uses-feature  android:name="android.hardware.camera.autofocus"  />

<!-- OpenGL ES 2.0 -->
<uses-feature  android:glEsVersion="0x00020000"  />
...

...
	<activity  android:name="{{ a }}"></activity>
	{% endfor %}
+		<provider
+			android:name="android.support.v4.content.FileProvider"
+			android:authorities="<YOUR PACKAGE NAME>"
+			android:exported="false"
+			android:grantUriPermissions="true">
+		<meta-data
+			android:name="android.support.FILE_PROVIDER_PATHS"
+			android:resource="@xml/file_paths"/>
+		</provider>
	</application>
</manifest>

NOTE: In <YOUR PACKAGE NAME> you must put the full package of the app. It is package.domain concatenated with package.name provided in buildozer.spec. Example:

# (str) Package name
package.name = myapp

# (str) Package domain (needed for android/ios packaging)
package.domain = com.my.domain

RESULT: com.my.domain.myapp

Then create a folder named xml in the .buildozer\android\platform\python-for-android\pythonforandroid\bootstraps\sdl2\build\src\main\res directory and create a file named file_paths.xml with the following code:

<?xml version="1.0" encoding="utf-8"?>
<paths  xmlns:android="http://schemas.android.com/apk/res/android">
	<external-path  name="external_files"  path="Android/data/<YOUR PACKAGE NAME>/files/Pictures"  />
</paths>

Don’t forget the package in this file too!

Now, build again: buildozer android debug deploy run. Don`t forget give permissions in app config screen.
The usage is similar to plyer module. The difference is that you will have to instantiate a CameraScreen object. After, call take_picture method with on_complete argument.

VERSIONS: buildozer == 0.39 cython == 0.29.10

I expect have helped. Sorry by my english, it don`t my native language. I would also like to thank everyone who contributed to this issue .

Might have found the solution. Basically, we need to use FileProvider class for the uri. For the most part just follow the instructions in here. https://developer.android.com/training/camera/photobasics.html

These are the modification I made to camera.py:

FileProvider = autoclass('android.support.v4.content.FileProvider')
Context = autoclass("android.content.Context")
Environment = autoclass("android.os.Environment")

I also added support-v4-24.1.1.aar, otherwise FileProvider class can’t be found.

Inside _take_picture function:

def _take_picture(self, on_complete, filename=None):

        def create_img_file():
            File = autoclass('java.io.File')
            storageDir = Context.getExternalFilesDir(Environment.DIRECTORY_PICTURES)

            imageFile = File(
                storageDir,
                "temp.jpg"
            )
            imageFile.createNewFile()

            return imageFile

        assert(on_complete is not None)
        self.on_complete = on_complete
        self.filename = filename
        android.activity.unbind(on_activity_result=self._on_activity_result)
        android.activity.bind(on_activity_result=self._on_activity_result)
        intent = Intent(MediaStore.ACTION_IMAGE_CAPTURE)

        photoFile = create_img_file()
        photoUri = FileProvider.getUriForFile(
            Context.getApplicationContext(),
            "org.test.myapp.fileprovider",
            photoFile
        )

        parcelable = cast('android.os.Parcelable', photoUri)

        intent.putExtra(MediaStore.EXTRA_OUTPUT, parcelable)
        activity.startActivityForResult(intent, 0x123)

The AndroidManifest.tmpl.xml will also need to be modified according to the instructions in the link.

But doing these will cause another problem where a duplication of the image will be saved to /DCIM/Camera

Is the solution push to plyer???

guokaiyi on Aug 19, 2019

Does anyone know how to correct this issue for android API level 30 (now required for the Play Store)? I’m having the same issue as the original post, however, when I try to apply the solution from @jefersonvinicius, the build fails with the exception that “Deprecated Gradle features were used in this build, making it incompatible with Gradle 7.0.” I believe this is due to the support.aar file being specific to API 24, but the latest file I could find supported up to API 28 (with nothing available for 30).

Using the bare camera.py file, I am able to get the native camera to pop up by changing the “file://” to “content://” but taking the photo doesn’t actually save the file… I’d like to be able to save my image to storage but can’t seem to get anything to work here… Any help or advice would be appreciated!

I can use camera in android API 27.

Add this file in your project folder. I created a folder named libs.

In buildozer.spec file I change these lines: Permissions: android.permissions = INTERNET, ACCESS_FINE_LOCATION, WRITE_EXTERNAL_STORAGE, CAMERA Add path to FileProvider lib: android.add_aars = ./libs/support-v4-24.1.1.aar

@tinyleafgreens Have you solved your issue, I’am facing the same problem…

javixav on Aug 21, 2023

is there is a fix for this problem? Buildozer doesnt copy the fileprovider xml file to directory

Use this p4a fork instead of bulldozer https://github.com/kivy/python-for-android/pull/1922

Fak3 on Mar 6, 2020

It is not included in the buildozer yet, so after installing this p4a you should build your apk like this:

p4a apk --private {app_root_dir} --version={app_version} --bootstrap=sdl2 --window --requirements=python3,kivy,openssl,sqlite3,pillow,pytz,sdl2,{requirements} --permission=CALL_PHONE --permission=INTERNET --permission=WRITE_EXTERNAL_STORAGE --permission=READ_EXTERNAL_STORAGE --orientation=portrait --dist-name test_my_build --fileprovider-paths=./fileprovider_paths.xml --package=org.example.mytest --name=“mytest” --release

Fak3 on Dec 14, 2019

@jefersonvinicius There is a PR adding fileprovider to the p4a: https://github.com/kivy/python-for-android/pull/1922 it will allow to do what you did manually above, by just specifying a path to your file_paths.xml during apk build.

Fak3 on Dec 13, 2019

I am sure I have solved the problem. Thanks IHadAFish and alecvn!

I am a kivy fan in China. For chinese kivy lovers, I’ve given an explanation in: https://www.pyfield.com/blog/?id=20#/

Expect kivy to become more popular!
