Problème avec buildozer empaquetant une application kivy

Question

J'essaye de préparer mon application kivy et j'ai des problèmes avec buildozer. Il y a quelques semaines, il a travaillé dans un bon sens, mais aujourd'hui j'ai eu cette erreur:

Traceback (most recent call last): 
    File "build.py", line 517, in <module> 
    make_package(args) 
    File "build.py", line 365, in make_package 
    subprocess.check_call([ANT, arg]) 
    File "/usr/lib/python2.7/subprocess.py", line 540, in check_call 
    raise CalledProcessError(retcode, cmd) 
subprocess.CalledProcessError: Command '['ant', 'debug']' returned non-zero exit status 1 

J'ai lu sur cette erreur (https://github.com/kivy/buildozer/issues/205) et peut-être le problème est avec la version du sdk et NDK. Ici, je joins mon fichier buildozer.spec parce que je fais peut-être quelque chose de mal.

# You can define all the "list" as [section:key].

# Let's take [app]/source.exclude_patterns. 
# Instead of doing: 
# 
#[app] 
#source.exclude_patterns = license,data/audio/*.wav,data/images/original/* 
# 
# This can be translated into: 
# 
#[app:source.exclude_patterns] 
#license 
#data/audio/*.wav 
#data/images/original/* 
# 


# ----------------------------------------------------------------------------- 
# Profiles 
# 
# You can extend section/key with a profile 
# For example, you want to deploy a demo version of your application without 
# HD content. You could first change the title to add "(demo)" in the name 
# and extend the excluded directories to remove the HD content. 
# 
#[app@demo] 
#title = My Application (demo) 
# 
#[app:source.exclude_patterns@demo] 
#images/hd/* 
# 
# Then, invoke the command line with the "demo" profile: 
# 
#buildozer --profile demo android debug 

Comme je l'ai dit au début de l'après il y a quelques semaines, il a fonctionné correctement et je ne sais pas pourquoi maintenant cela me passe. Juste au cas où le journal complet des buildozer est nécessaire, j'Accrocher ici les dernières lignes de la sortie en utilisant buildozer --verbose android debug:

Answer 1

Eh bien, après avoir cherché la réponse dans certains forums, j'ai réalisé la bonne façon de résoudre le problème . Dans le fichier buildozer.spec j'ai changé la version sdk à la dernière version avaible:

# (int) Android SDK version to use android.sdk = 24

Après que j'exécuté buildozer et essayé de télécharger la version que j'ai spécifié dans le fichier .spec, et cette fois la création de le fichier apk était bien fait.
