Kivy garden mapview deploying error with Buildozer

I am using kivy.garden.mapview for my application. Everything works properly, but problems arise when I try to deploy the application to Android with Buildozer. I set "garden_requirements = mapview" in the .spec file, and I always get the same error message: "Command failed: garden install --app mapview". The command fails even when I execute it on its own. The command "buildozer android debug deploy run logcat" produces the following output:

I have tried everything I found on Stack Overflow, but nothing worked. Any suggestion?

The problematic error stems from this piece of information here:
Kivy-Garden==0.1.1
I had the same issue, buildozer, for some weird reason installs Kivy-Garden version 0.1.1 which produces that error when you try to install ANY garden flower. Kivy version 1.11.1 now uses Kivy-Garden>=0.1.4 which works without issues.
If you install Kivy-Garden==0.1.1 and try to install a package, it crushes with that error. However, If you upgrade to Kivy-Garden==0.1.4. The problem is that buildozer will install Kivy-Garden==0.1.1 no matter what you do. So I tried a lot of things from downgrading buildozer to manually activating the environment that buildozer creates and upgrading garden there but when you run the buildozer command again. Buildozer will simply overwrite your upgraded garden AND install the non-working 0.1.1.
Finally I just gave up and did the one thing I COULD do at this moment. Simply fix buildozer myself:
Activate your environment(assuming you have one)
Go to where buildozer is installed. In my case this is: /home/samuel/repo/mobile/venv/finager/lib/python3.7/site-packages/buildozer-1.2.0.dev0-py3.7.egg/buildozer/__init__.py. You can find that out by checking the paths in your logs.
Now go to Line 533 and change where it says pip install Kivy-Garden==0.1.1 to pip install Kivy-Garden==0.1.4
That's it, your problem should go away now.
I hope they fix this soon as this is a pretty simple thing to do. Kivy itself requires Kivy-Garden>=0.1.4 which makes me wonder why buildozer would want 0.1.1 when it clearly doesn't work

# Then, invoke the command line with the "demo" profile:
#
#buildozer --profile demo android debug
I need help getting around this issue. Thank you in advance.

maybe you need this :
#(list) Gradle dependencies to add
#android.gradle_dependencies =
because your buildozer.spec doesn't exist

Can't build Kivy project with buildozer and python3crystax

Sorry for possible stupid question, but today I spent ~5 hours trying to build simple apk with Python3, Buildozer and Crystax NDK. I used Buildozer VM, downloaded Crystax ndk 10.3.2, created buildozer.spec as follow on github instruction https://github.com/kivy/buildozer . My buildozer.spec:
title = Cyba app
package.name = cyapp
package.domain = ru.longint
source.dir = .
requirements = python3crystax,kivy
android.ndk_path = ~/.buildozer/crystax-ndk
and few others.
When I run buildozer -v android debug to make first compilation (by the instruction on the Buildozer's wiki), I got next logs:
# Check configuration tokens
# Ensure build layout
# Check configuration tokens
# Preparing build
# Check requirements for android

And here's my questions:
1)What is python3crystax literally? Is a pip package, utility, file or what?
2)Must i download python3crystax manually and where i can to download this?
3)What i did wrong?
UPD:
I found this question and tried buildozer -v android_new debug
Got this (log_level in buildozer.spec is 2):

I see some weird string in logs. I really have not this path in Crystax ndk folder.
[WARNING]: include directory doesn't exist: /home/kivy/.buildozer/crystax-ndk/sysroot/usr/include/arm-linux-androideabi

Download and extract the Crystax NDK somewhere e.g. /opt/
Make sure the following lines are in your buildozer.spec file.:
Require python3crystax:
requirements = python3crystax,kivy
Point to the directory where you extracted the crystax-ndk:
android.ndk_path = /opt/crystax-ndk-10.3.2

Any help with what may be causing this error or even how to see more of the Ant build error would be great.

I got same error but solved.

Buildozer build error that seems to do with some ant file

I tried running buildozer using VM on my Windows computer. I used python 3 so I got python3crystax downloaded. I tried packaging the app with the usual 'buildozer android debug' command. Everything was fine until I received the log below. Can someone tell me what went wrong and how I can fix it?

So the above happened and stopped building process. Also another thing I noticed in the logs were the lines below with lots of warnings, although these lines didn't stop the process of building (these lines appeared earlier in the sequence). Perhaps there's something I'm missing here as well?
