Using Python/Buildozer to compile Kivy for Android

[montyonthebonty]

Hi

I'm trying to compile a Kivy project for Android using buildozer and it's not working. I've managed successfully in the past, but I think that a Mac upgrade has messed it up. The bit it seems to get stuck on is this:

Any ideas why?

Thanks

I don't know what's happening here, but it looks like a general problem with SSL in your python installation, rather than something internal to buildozer.

I would try downloading things with the same python installation in different ways, e.g. with the requests module. Does that result in similar problems?

If this does turn out to be related to buildozer in particular, I'll reopen the issue.

Good evening Thanks for replying - I’ve been saving this until I’ve had time to properly digest it, but I’m afraid I’m quite new to all this and I’m not entirely sure what you mean. I spent quite a lot of time on Google trying to find a solution, downloading and updating various things, but I am afraid I was groping blindly in the dark to a large extent. Are there any books or anything that might help me? Thanks Chris
