AsyncImage not loading

[Arelfox]

I've searched a for an answer for a while now, but haven't found one.

On a computer, the async images load perfectly, but when I put it on mobile, the images show a box with an red X on it after loading for a few seconds

I have given kivy internet permissions

No one else seems to have the same issue

First look for an error message, otherwise we are guessing.

You are not alone https://github.com/kivy/python-for-android/issues/1827

[Arelfox]

After looking in logcat, it was indeed a SSL: CERTIFICATE_VERIFY_FAILED error. However, using the proposed " os.environ['SSL_CERT_FILE'] = certifi.where()" line had no effect.

[Robert]

Yes, it should be sufficient to include certifi in requirements.

Don't fight it, use requests and a thread.

[Arelfox]

I also tried to see if it was missing the env variable SSL_CERT_FILE, and it was not.

[Arelfox]

What do you mean by requests and a thread?

[Robert]

https://requests.readthedocs.io/en/latest/

https://docs.python.org/3/library/threading.html

[Arelfox]

For each AsyncImage, it's source is a https link to an image.

I don't quite understand how to use requests and threading to achieve the same thing, though...am I missing something?

[Robert]

You may be missing something, but I don't have any way to know what that would be.

use requests to get the image file.

do it in a thread so you don't block the Kivy event loop

set the Image source to your downloaded  file (from the Kivy main thread)

Nothing in the above is Kivy specific, except the Kivy main thread.

I know this works, but I switched to AsyncImages with urls because i couldn't figure out why PIL wasn't saving the image. It would always throw file or directory not found in the im.save() function. Does os.getcwd() not work inside kivy apps?

[Arelfox]

I found a solution!

ssl._create_default_https_context = ssl._create_unverified_context

[Robert]

Consider sharing your finding on GitHub.

I expect os.getcwd works as usual on all platforms, it is not part of Kivy.
