I have a problem loading images with the object AsyncImage generates an error, when I load images from the internal memory I have no problems.
My code is _:
#qpy:kivy
import kivy
kivy.require('1.10.0')
from kivy import App
from kivy.uix.gridlayout import GridLayout
from kivy.uix.image import Image, AsyncImage
layout = GridLayout(cols = 2)
picture = Image(source = "/sdcard/qpython/cat.jpg")
btn = Button ( text = "aceptar")
Pictureurl = AsyncImage(source = "https://commons.wikimedia.org/wiki/File:Firefox_Nightly_Logo,_2017.png")
layout.add_widget(picture)
layout.add_widget(btn )
layout.add_widget(Pictureurl)
class MainApp(App):
def build(self):
return layout
MainApp().Run()
The code works well for local images but when I try to extract the resource from the internet it gives me an error in the library PIL raise AttributeError(name) AttributeError: tobytes
does not load the image and stops the execution of the script
Data I'm using these settings
[kivy ]v1.10.0
[python ]v2.7.12
[Image ] Providers: img_tex, img_dds, img_pygame, img_pil, img_gif
[Text ]Providers: pygame
This is the complete code after fixing the URL:

try to modify the code to load an image with the Loader element but I get the same error, possibly the libraries do not work, I do not understand the error.
