我搜索了错误，但我找不到一个好的解决方案，大多数答案适用于Windows或Mac但不适用于Linux

sdk = /home/myland/Documents/tools
platform-tools = /home/myland/Documents/tools/platform-tools

我该怎么办？

Answer 1

我将java更新到版本8并安装Gradle并制作AVD android 现在好了

# cordova requirements
Requirements check results for android:
Java JDK: installed 1.8.0
Android SDK: installed true
Android target: installed android-26,android-25
Gradle: installed /usr/share/gradle/bin/gradle

Answer 2

如果有任何正文在linux中得到错误就可以了第一步下载最新的Android stdio，JDK持续和NodeJs安装cordova

npm install -g cordova --save

第二步

export ANDROID_HOME=/home/user/Android/Sdk
export PATH=${PATH}:$ANDROID_HOME/tools:$ANDROID_HOME/platform-tools
/home/user/android-studio/gradle/gradle-4.1/bin/gradle

如果在主页文件夹中安装下载谢谢

Android目标：未安装在Ubuntu中
