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

How to fix cp issue during build with ninja?

I am currently compiling a custom recovery for an android phone. Sources are synced, device tree etc. all set up correctly. Now I am facing a rather banal-looking error during build. cp refuses to copy a directory, because -r is not specified in the build file.
I obviously tried to find the build file (rw_recovery/out/build_omni_daisy.ninja) and add the -r argument, but it seems to be regenerated at the beginning of every build process, as the process still fails and the previously changed line appears unchanged when opening the file after the attempted build.
These are the build steps:
. build/envsetup.sh
lunch omni_daisy-eng #config for the device
mka bootimage #device uses boot.img as recovery
This command leaves me with the following error:
[ 99% 6883/6884] Prebuilt (rw_recovery/out/target/product/daisy/kernel)
FAILED: rw_recovery/out/target/product/daisy/kernel
/bin/bash -c "(rm -f /home/luca/rw_recovery/out/target/product/daisy/kernel) && (cp rw_recovery/out/target/product/daisy/obj/KERNEL_OBJ/arch/arm64/boot/ rw_recovery/out/target/product/daisy/kernel )"
cp: -r not specified; omitting directory 'rw_recovery/out/target/product/daisy/obj/KERNEL_OBJ/arch/arm64/boot/'
ninja: build stopped: subcommand failed.
17:13:06 ninja failed with: exit status 1
I would love to hear any suggestions about how to force ninja to execute the command with -r. Alternatively, suggestions about where to find the file from which the above mentioned build file is recreated after executing mka command are much welcomed as well.

Buildozer error : Command failed: ./distribute.sh -m "kivy" -d "randomapp"

I have a simple project written in python (kivy) and i am using buildozer to make .apk file for Android platform. But for some reason the compiling it's not sucessufull. I think it's a problem with the pythoh-for-android module because it gives me the error:
# Command failed: ./distribute.sh -m "kivy" -d "randomapp"
#
# Buildozer failed to execute the last command
# The error might be hidden in the log above this error
# Please read the full log, and search for it before
# raising an issue with buildozer itself.
# In case of a bug report, please add a full log with log_level = 2
But when i added log_level = 2 , i see that it says that lpng is missing:
/home/shakle17/shakle/rand0m/.buildozer/android/platform/python-for-android/bui/home/shakle17/.buildozer/android/platform/android-ndk-r9c/toolchains/arm-linux-androideabi-4.8/prebuilt/linux-x86_64/bin/../lib/gcc/arm-linux-androideabi/4.8/../../../../arm-linux-androideabi/bin/ld: error: cannot find -lpng
collect2: error: ld returned 1 exit status
I am using Fedora23 and i've installed all libraries (libpng , libpng-devel for x64 and i686 platform) in the dnf package manager but still the problem remains .

I've fixed it . I've installed libpng from the official site, than run : buildozer android clean and after that it was fixed

Building an APK for android from a Python/Kivy source code

I am on trying to move a python/kivy app from a virtual machine to android device. Here is what I did:
git clone https://github.com/kivy/buildozer.git
cd buildozer
sudo python2.7 setup.py install
to get buidozer. Then change the project directory from the shared folder to code/kivy/examples/demo and then type buildozer init to get buildozer spec and finally type buildozer android debug deploy run to build the apk.
I got the following error message:

Thanks in advance for any help.

To fix this issue run this command buildozer android clean
and then rebuild it using buildozer android debug or automatically run using buildozer android debug deploy run.
And also this link might help.

Looks like you've just made a new ios/apk package. It is persisent with buildozer... All you need to do though is
buildozer android update
buildozer android release

Restart your terminal.

You don't have SDK correctly installed on you computer. (Path or SDK update)
It's write on your error log : You may not have the required environment or OS to build this project

you just need to install ant
sudo apt-get install ant
then do the same as before,its work correctly
