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.

I am working on a kivy android app and while building the apk got the below error. The error is saying that opencv requires android sdk release version 14 or newer but when i check the version where i can find the sdk install path i can find it as 30.0.4. Below are the logs

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
Writing my first Android app in Python and using Buildozer to package it. Because I will need to use numpy later on in the project, I tried packaging the following test code:
import numpy
import kivy
kivy.require('1.0.6')
from kivy.app import App
from kivy.uix.button import Button
class TestApp(App):
def build(self):
return Button(text='Hello World')
TestApp().run()
However, I got the following error:

Also, here is my buildozer.spec file:
title = My Application
package.name = myapp
package.domain = org.test
source.dir = .
source.include_exts = py,png,jpg,kv,atlas
version = 1.0
requirements = kivy,numpy
orientation = portrait
osx.kivy_version = 1.9.1
fullscreen = 0
android.api = 19
android.sdk = 20
android.ndk = 9c
android.arch = armeabi-v7a
log_level = 2
warn_on_root = 1
Note that when I removed "import numpy" from the python code and removed "numpy" from the requirements list in the buildozer.spec file, my code was packaged perfectly. I am running this on VM Virtual Box which had Buildozer pre-installed.
Also it is not just Numpy giving me this issue- OpenCV is giving me the exact same errors. Will make separate post for that if needed.
This issue is reported in Python for Android (p4a) project here, didn't knew it's actual for stable p4a. Nevertheless, by link you can find PR that fixes issue. I didn't test it, but different people say it works.
You can try to build numpy with this fix, here's what you'll need:
Make sure you clean all left from current building process with command:
buildozer distclean
Clone p4a branch with fix using command:
git clone -b p4a_numpy_fix https://github.com/mahomahomaho/python-for-android fix-numpy
Change your buildozer.spec to use this cloned version of p4a (use your actual path):
p4a.source_dir = /home/ubuntu/p4a_numpy_fix
And run building apk again. If everything will work fine, you'll be able to build apk. If not you'll face another errors, no guarantees here :(

I am not getting that what I am missing. Appreciate your help.

Try older version of NDK (15 or older) and make sure /Android/sdk/ndk-bundle contains a directory with that version so it looks like /Android/sdk/ndk-bundle/android-ndk-r15.
I had the same error when trying to build the sample Android APP. I tried several things to clearly understand the behaviour of the .buckconfig settings and environment variables.
Set ndk_path
you can set ndk path directly. I've set this variable instead of setting ndk_version(such as 'r10e') Keep in mind that
The environment variables ANDROID_NDK and NDK_HOME both supercede
the buckconfig setting.
Create a repo folder (recommended)
Download ndk bundle and unzip it into a folder that serves as a repository folder and set it to ANDROID_NDK_REPOSITORY env var. So the path can be used to get the correct ndk version. In this case only thing you have to do is setting the version of NDK bundle and buck will automatically get the right version for you.
Currently there is error with Buck with the Java9.
Just to add more.
If you are using java9 then downgrade to java8 as buck uses the sun/misc/BASE64Encoder which is removed in java9.
To keep versions of java8 and java9 in mac. I have implemented below command lines in .bash_profile.
export JAVA_8_HOME=$(/usr/libexec/java_home -v1.8)
export JAVA_9_HOME=$(/usr/libexec/java_home -v9)
alias java8='export JAVA_HOME=$JAVA_8_HOME'
alias java9='export JAVA_HOME=$JAVA_9_HOME'
#default java8
export JAVA_HOME=$JAVA_8_HOME
I have a question about tensorflow porting to android devices. When I was in centos, using bazel compiler generated apk file, suggesting the following error:

I ask you have encountered similar problems? please help me.
I was facing the same problem, this is how I fixed it:
# Uncomment and update the paths in these entries to build the Android demo.
android_sdk_repository(
name = "androidsdk",
api_level = 24,
# # Ensure that you have the build_tools_version below installed in the
# # SDK manager as it updates periodically.
build_tools_version = "25.0.3",
# # Replace with path to Android SDK on your system
path = "/home/yours/Android/Sdk/",
) #my mistake #) --> )
#
# Android NDK r12b is recommended (higher may cause issues with Bazel)
android_ndk_repository(
name="androidndk",
path="/home/yours/android-ndk-r12b/",
# # This needs to be 14 or higher to compile TensorFlow.
# # Note that the NDK version is not the API level.
api_level=14)
