kivy-example 上的 Buildozer 无法构建 apk

Question

我已经安装了 kivy（在 debian jessie / python 2.7 上），示例运行良好，

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，它会出现错误。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暗示可能是什么问题的东西

另外，在我尝试构建的某个时间点，每次我运行 buildozer 时它都会下载 android sdk，但现在停止了.. 或者至少它不再达到那个点了。

升级到 python 3 然后安装 python3-kivy 是否可以解决这个问题？我注意到我当前的安装没有获取最新的（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。我能找到的唯一另一件事是将java8降级到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 目前已过时。忘了它。我在这里被问到了：Buildozer gives error upon building Pong app of Kivy framework for android publishing

试试Python for Android 或QPython
