【已解决】mac上appium报错：“Could not find aapt Please set the ANDROID_HOME environment variable with the Android SDK root directory path”

按照网上教程配置完appium环境后，真机跑自动化过程，遇到如下报错：

appium报错如下：

[ADB] Checking whether aapt is present
[ADB] The ANDROID_HOME environment variable is not set to the Android SDK root directory path. ANDROID_HOME is required for compatibility with SDK 23+. Checking along PATH for aapt.

[ADB] Error: Could not find aapt Please set the ANDROID_HOME environment variable with the Android SDK root directory path.

首先，使用appium-doctor进行配置检查

appium-doctor校验结果，ANDROID_HOME等路径均已经配置：

info AppiumDoctor

info AppiumDoctor

其次，检查环境变量$ANDROID_HOME和aapt，也是OK的。

➜  ~ echo $ANDROID_HOME
/Users/uc/Library/Android/sdk4eclipse

➜  lib aapt
Android Asset Packaging Tool

Usage:
 aapt l[ist] [-v] [-a] file.{zip,jar,apk}
   List contents of Zip-compatible archive.

最后，命令行appium解决问题

后来，网上看到一个提问（可惜忘记保存链接），题主提到他命令后启动正常，手工启动appium才有问题。我尝试使用命令后启动appium后，问题果然解决。

命令行启动appium:

/Applications/Appium.app/Contents/MacOS/Appium
