当我运行“ buildozer android debug”时，出现此错误，关于jave也是一样！ 我不确定 ;在运行命令后，无论如何我都会得到：
这是我在终端上运行的所有命令，我认为与该问题有关
$ apt-get update
$ apt-get install default-jdk
enter code here$ wget https://dl.google.com/android/repository/sdk-tools-linux-3859397.zip
$unzip sdk-tools-linux-3859397.zip
$ export PATH=/opt/pradip/tools:/opt/pradip/tools/bin:/usr/local/sbin:/usr/local/bin:
/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:/usr/local/bin
