python - Buildozer 如何解决 "--ndk-api=21"错误

Question

我有一个基于 kivy-python 的 Android 小应用程序。要将其转换为 APK，我必须使用 buildozer。

当我运行最后一步时:

buildozer android debug deploy run 我收到此错误。

我更改了规范文件中的 NDK 值，或者更改了代码。简而言之，我所做的就是查看类似的错误。我尝试了报告的解决方案，但它们不起作用。我什至不知道问题出在哪里。

我解决了这个问题。如果有人遇到这个错误，我按照以下步骤解决了

sudo apt update

sudo apt-get install autoconf

pip install --upgrade buildozer

sudo apt install -y git zip unzip openjdk-8-jdk python3-pip autoconf libtool pkg-config zlib1g-dev libncurses5-dev libncursesw5-dev libtinfo5

pip3 install --user --upgrade cython virtualenv
