我已经安装了我的 android sdk，我也安装了 java。

这是我的.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 。 但是这个错误仍然存​​在。 我该如何解决这个问题？

Answer 1

请在文件夹android创建文件local.properties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

您需要在系统路径中的环境变量和工具和平台工具中添加ANDROID_HOME、JAVA_HOME变量才能运行android apk。

在环境变量中设置ANDROID_HOME变量。

在环境变量中设置JAVA_HOME变量。

Answer 3

所以我的问题的解决方案是：

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

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