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

App construction generates error in toolchain.py by unrecognized argument

Versions
Python: 2.7
OS: Linux Lite (Ubuntu)
Kivy: 1.10.1
Cython: 0.22
Buildozer does not proceed with the creation of the App by an error in toolchain.py and arguments --ndk-api 9.
I switched to all cython versions from 0.21 to the latest, but nothing has changed. I went in the android sdk folder and made several updates, however the problem still persists.
the error is: 'toolchain.py: error: unrecognized arguments: --ndk-api 9'

would anyone know the reason for this error?

for other people who may have this same problem, I put here everything I did to solve the bug.
Ok, first, this was a bug where the buildozer.spec file for some reason did not properly update the p4a files and there was also an error with the version of ndk used.
First I downloaded the r17c version of NDK. I went to the /home/dev/.buildozer/android/platform/ path and extract the downloaded file.
Then in the path /home/dev/buildozer/buildozer/default.spec I changed the branch used in p4a for the master and it looked like this:
# p4a.branch = master
I have also changed the following lines:
# (int) Android API to use
# android.api = 21
# (int) Minimum API required. You will need to set the android.ndk.api to be as low as this value.
# android.minapi = 21
# (int) Android SDK version to use
# android.sdk = 20
# (str) Android NDK version to use
# android.ndk = r17c
# (int) Android NDK API to use (optional). This is the minimum API your app will support.
# android.ndk_api = 19
Well, that initially did not change anything in the way the construction was being done and it continued to make a mistake. So I went on the path
/ home / dev / buildozer / buildozer / targets /
and in the file android.py I changed lines 17, 18 and 20 thus:
ANDROID_API = '21' #line 17
ANDROID_MINAPI = '21' #line 18
ANDROID_SDK_VERSION = '20'
ANDROID_NDK_VERSION = '17c' #line 20
APACHE_ANT_VERSION = '1.9.4'
in this same file, in the TargetAndroid class I changed lines 46 (the old name is python-for-android-new-version) and 47, the class looks like this:
class TargetAndroid (Target):
targetname = 'android_old'
p4a_directory = "python-for-android" #line 46
p4a_branch = 'master' #line 47
p4a_apk_cmd = "python build.py"
Ok, in this same path has a file called android_new.py, in the TargetAndroidNew class I changed lines 16 and 17, the class looks like this:
class TargetAndroidNew (TargetAndroid):
targetname = 'android'
p4a_branch = "master" #line 16
p4a_directory = "python-for-android" #line 17
p4a_apk_cmd = "apk --debug --bootstrap ="
extra_p4a_args = ''
Ok, this should already work, but for some reason there is another path with pretty much the same files, so I made the same changes. No path
/home/dev/buildozer/build/lib.linux-x86_64-2.7/buildozer/
I changed the default.spec file as I had done previously. And in the path
/home/dev/buildozer/build/lib.linux-x86_64-2.7/buildozer/targets/
I've changed the files android.py and android_new.pyin the same way as I previously did.
Now the buildozer performs the proper update of p4a and ndk and works correctly.

Buildozer error when compiling Android: list index out of range inside _install_p4a

I'm currently trying to compile a simple Kivy app for use on Android. It runs in both my windows and linux environments without errors or warnings. When I go to package it using buildozer I get an error almost immediately. I did search for this error and although the title is very similar to other questions, the error is not.

My environment:

cython version=0.25.2
python version=3.6.6
OS is Ubuntu=18.04
Am I mixing and matching the wrong versions of things?

This seems a like a bug in the latest version of buildozer. The solution is to edit the file "../python3.6/site-packages/buildozer/targets/android.py" and replace the line
deps = re.findall("^install_reqs = (\[[^\]]*\])", setup, re.DOTALL | re.MULTILINE)[0]
with
deps = re.findall("install_reqs = (\[[^\]]*\])", setup, re.DOTALL | re.MULTILINE)[0]
Then run buildozer -v android debug

Build apk using buildozer and kivy Error with gradlew (new project)

I have been able to build an .apk file by kivy and python2.7 using buildozer, and the app works fine on phone-device. After a while, i started a new project in a new folder (together with new main.py), but when i do buildozer android debug, the Error attached keeps coming out, something with gradlew. In my previous builds, this never happens.
In this new main.py, i previously use numpy module, but this module cause Error also in the build-up. So i removed it and rewrite the code. Now another Error occurs (the Error because gradlew).
I have tried added android in the requirements. Does not work. (although i prefer to use the default buildozer.spec).
I appreciate some inputs on this.
*Also, i found some official resources, either from Github or the buildozer site are a bit inconsistent. Is there a detail resource such that i may install buildozer correctly, also the guide for the buildozer.specs?
I even not fully remember why the previous app works well..because i also bumped into several problems before the 1st App works fine.
** When i debug the new main.py in the old folder, the build process succeed.**
** (I also use the same package.name and package.domain as the 1st App) **
Thanks in advance.

This error mostly occurs when you've interrupted the system when Gradle was downloading.
You can simply fix this by manually downloading gradle from https://services.gradle.org/distributions/gradle-4.4-all.zip
Then replace the gradle-4.4-all.zip.part in /your/home/path/.gradle/wrapper/dists/gradle-4.4-all/4th6d42q1kgladv9hkn2iehgi5 with the new dowloaded file

I had the same problem to solve mine I downloaded an earlier version of buildozer and it worked

Python, Kivy, Buildozer: error using python-firebase/requests

[Python = 2.7]
I recently started to use kivy (newest version) to develop an app for Android. For this I use buildozer (newest version) to create the apk file. Now everything works fine on my computer even using the python-firebase module. To send data to the Firebase online database. But when I want to use the Python module python-firebase (that is based on the module requests) on my phone the app crashes after it loads for a few seconds.
For now my requirements in the buildozer.spec are plyer and kivy. If I try to add requests to this list, I get the error:

Do I need to add requests to the requirements, since it is done in an example in the documentation of using buildozer? What can I do to make python-firebase working on my Android device? I have no knowledge about how to make a recipe and can't find any good documentation about this. Could making a recipe work? Has anyone tried to get Firebase working with Python on Android?

There is an issue for Firebase working on python Kivy. See https://github.com/ozgur/python-firebase/pull/26
This is because multicore processing is not fully supported on Kivy, which is used by Firebase. This caused the crash on kivy Firebase apps.
I haven't tried the patch yet, but looking at the comments, Zkanda did good. This might be what you're looking for.
Alternatively, you can use json to download data from Firebase.
What I did to use Firebase was to use python's native Requests library to make a json call to Firebase, which they support with https.
import json, requests
url = "https://myfirebaseurl.firebaseio.com/some_database.json"
resp = requests.get(url = url, json = {'create':True})
data = resp.json()
In your buildozer.spec file, under the Requirements, include
requirements = kivy,requests,simplejson,openssl
openssl is to support https, simplejson is for json.

no such option: --download-cache
This reflects a bug in python-for-android that is now fixed. If you make buildozer re-download python-for-android, e.g. by deleting the .buildozer dir in your build directory, it should work.
You can also edit the current downloaded distribute.sh to remove the --download-cache option when calling pip.

I tried the suggested solution when encountering a similar issue with pygments, and it didn't work for me either. I increased log levels and found that pygments was being downloaded to lib64/python on my distro, whereas pip was looking for lib/python.
It appears to be related to this pip issue: https://github.com/pypa/pip/issues/3056
I added a setup.cfg file in the .buildozer folder for my app, containing:
[install]
install-purelib=$base/lib64/python
and my app now installs successfully.
