我已经安装了android，也安装了java。

这就是我的.bach_profile

export ANDROID_HOME=$HOME/Library/Android/sdk
export PATH=$PATH:$ANDROID_HOME/tools
export PATH=$PATH:$ANDROID_HOME/platform-tools
export JAVA_HOME=$Home/Library/Java/JavaVirtualMachines/jdk1.8.0_101.jdk/Contents/Home

我尝试添加一个local.properties文件，并添加指向我的Android/sdk文件夹的sdk.dir。但这一错误仍然存在。我该怎么解决这个问题？

Answer 1

请将文件local.properties放在android文件夹中，然后在文件中添加以下行

sdk.dir=/Users/apple/Library/Android/sdk(Please add your sdk path here)

Answer 2

您需要在环境变量和工具中添加ANDROID_HOME、JAVA_HOME变量，并在系统路径中添加平台工具来运行android。

在环境变量中设置HOME变量。

在环境变量中设置HOME变量。

Answer 3

所以解决我的问题的方法是：

1)在我的ANDROID_HOME和JAVA_HOME路径中添加.bash_profile

2)创建local.properties并在sdk.dir=<PATH TO ANDROID SDK>文件夹中添加sdk.dir=<PATH TO ANDROID SDK>。
