Kivy：Buildozer.spec文件未完成

Question

我准备使用kivy buildozer。对于安装，我使用了here的指令，进程​​为python 3.在第3步之后，buildozer.spec文件没有完成，检查行（步骤4）有下一个内容：

requirements = kivy
#android.ndk_path = 

buildozer android debug deploy run之后的安装消息：

# Unpacking Android NDK
# Android NDK installation done.
# Check application requirements
# Check garden requirements
# Compile platform
# Command failed: /usr/bin/python -m pythonforandroid.toolchain create --dist_name=myapp --bootstrap=sdl2 --requirements=kivy --arch armeabi-v7a --copy-libs --color=always --storage-dir=/media/sf_ForBuildozer/.buildozer/android/platform/build
# 
# Buildozer failed to execute the last command
# If the error is not obvious, please raise the log_level to 2
# and retry the latest command.
# In case of a bug report, please add a full log with log_level = 2

问题的根源是什么？

我将log_level = 2添加到section buildozer，New message：

# Run '/usr/bin/python -m pythonforandroid.toolchain create --dist_name=myapp --bootstrap=sdl2 --requirements=kivy --arch armeabi-v7a --copy-libs --color=always --storage-dir=/media/sf_ForBuildozer/.buildozer/android/platform/build'

我应用了米哈伊尔·格拉西莫夫的建议，并在短暂的步骤后获得了新的消息：

# Run '/usr/bin/python -m pythonforandroid.toolchain create --dist_name=myapp --bootstrap=sdl2 --requirements=kivy --arch armeabi-v7a --copy-libs --color=always --storage-dir=/media/sf_ForBuildozer/.buildozer/android/platform/build'

Answer 1

这里的问题是SDK不包含为目标API构建的所有内容。通常buildozer自动处理它，但不时it breaks。您可以通过GUI手动安装东西（参见上面的链接）或者我通常通过（linux）控制台进行操作：

echo y | android-sdk-linux/tools/android update sdk --all --no-ui --filter tools
echo y | android-sdk-linux/tools/android update sdk --all --no-ui --filter platform-tools
echo y | android-sdk-linux/tools/android update sdk --all --no-ui --filter build-tools-27.0.2
echo y | android-sdk-linux/tools/android update sdk --all --no-ui --filter android-19

确保您的SDK目录在android-sdk-linux/tools/android上可用。安装完所有这些之后我认为错误应该去了。
