Question

我已经安装了kivy（在debian jessie / python 2.7上），示例工作正常，

sudo dpkg --add-architecture i386
sudo apt-get update
sudo apt-get install -y build-essential ccache git zlib1g-dev python2.7 python2.7-dev 
sudo apt-get install libc6-i386 lib32stdc++6 lib32gcc1 lib32ncurses5 
sudo pip install colorama appdirs sh jinja2 six
sudo pip install --upgrade colorama
sudo apt-get install pkg-config autoconf automake libtool
sudo apt-get install software-properties-common
sudo apt-get install cython  #installs 0.21.1
sudo add-apt-repository ppa:kivy-team/kivy
sudo apt-get update
sudo apt-get install python-kivy python-kivy-examples  #installs 1.8.0
sudo chmod -R 777 /usr/share/kivi-examples/  #install made it Read-Only Root
sudo pip install --upgrade buildozer  #installs 0.32
sudo easy_install buildozer  #just in case?
sudo pip install python-for-android  #0.4?
java -version #reports 1.8.0_121

但是当我尝试构建任何kivy示例时，它会出错。我在.spec文件中设置了log_level = 2，但我在控制台输出中没有看到任何可能出现问题的内容

/usr/share/kivy-examples/demo/touchtracer$ buildozer init

此外，在我尝试构建的某个时刻，每次运行buildozer时都会下载android sdk，但现在停止了..或者至少它不再是那个点了。

有可能升级到python 3然后安装python3-kivy会解决这个问题吗？我注意到我当前的安装没有抓住最新的（kivy 1.9.1 / android sdk 21）

[更新＃1]我安装了较新版本的buildozer（.33dev），cython（25.2）和kivy（1.9.2.dev0）

cd ~
git clone https://github.com/kivy/buildozer.git
cd buildozer
sudo python setup.py install
cd ..
sudo pip install Cython==0.25.2  #kivy 1.9.2.dev0 required Cython >= 0.23
git clone https://github.com/kivy/kivy
cd kivy
sudo python setup.py install

并更新了.spec文件：

requirements = python2,kivy==master
android.sdk = 24

但仍然没有运气。我能找到的另一件事就是将java8降级为java7。 buildoze不适用于8吗？ Buildozer command failed

[更新＃2]我卸载了Java8（https://askubuntu.com/questions/84483/how-to-completely-uninstall-java）并安装了Java 1.7.0_80，但我得到了同样的错误

sudo apt-get install oracle-java7-installer
java -version
sudo apt-get install oracle-java7-set-default
sudo update-alternatives --config java

BuilDozer到现在已过时。算了吧。我按照这里的要求坚持使用：Buildozer gives error upon building Pong app of Kivy framework for android publishing

尝试Python for Android或QPython

在kivy-example上的Buildozer无法构建apk
