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'

last part of log:

would anyone know the reason for this error?

Solution

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.
