一、配置环境变量
- 首先找到 SDK 安装位置
- 可以通过 AndroidStudio -Tools - Android - SDKManager 找到位置
- 创建 .bash_ 文件
export PATH=${PATH}:/Users/xxxx/Application/android-sdk-mac_x86/tools:/Users/xxxx/Library/Android/sdk/platform-tools
+输入 source .bash_来立即生效刚才的配置。
- 之后可以使用 adb 命令来验证。
- 如果没有出现 command not found 那么配置成功
二、权限问题
- 模拟器环境
localhost:~ xxx$ source .bash_
localhost:~ xxx$ adb shell
//如果此时输入一些命令，会出现没有权限的信息
generic_x86:/ $ls
ls: ./ueventd.rc: Permission denied
ls: ./ueventd.ranchu.rc: Permission denied
ls: ./ueventd.goldfish.rc: Permission denied
