Mac 运行aapt命令 提示：zsh: command not found: aapt 这个问题是Mac本地没有配置 aapt的 环境变量。理论上本地有Android Studio，aapt是默认配置了的，无奈要用到aapt，还是配置下吧。
mac zsh 配置 aapt 环境变量的方法：
1.在终端输入 open ~/.zshrc 打开zsh环境变量保存的文件。也可以手动去打开
2.进入到Android Studio目录，找到自己 Mac 中 aapt 工具的存放目录：例如我的为：/Users/jason/Library/Android/sdk/build-tools/31.0.0
3.在 .zshrc 文件中添加环境变量配置。
AAPT_HOME=/Users/jason/Library/Android/sdk/build-tools/31.0.0
export AAPT_HOME
export PATH=${PATH}:$AAPT_HOME4. 然后保存设置：
source ~/.zshrc5.测试aapt 是否work：
aapt --helptest result:

Multiple directories will be scannedand the first match found (left to right) will take precedence.-0 specifies an additional extension for which such files will notbe stored compressed in the .apk. An empty string means to notcompress any files at all.--debug-modeinserts android:debuggable="true" in to the application node of themanifest, making the application debuggable even on production devices.--include-meta-datawhen used with "dump badging" also includes meta-data tags.--pseudo-localizegenerate resources for pseudo-locales (en-XA and ar-XB).--min-sdk-versioninserts android:minSdkVersion in to manifest. If the version is 7 orhigher, the default encoding for resources will be in UTF-8.--target-sdk-versioninserts android:targetSdkVersion in to manifest.--max-res-versionignores versioned resource directories above the given value.--valueswhen used with "dump resources" also includes resource values.--version-codeinserts android:versionCode in to manifest.--version-nameinserts android:versionName in to manifest.--replace-versionIf --version-code and/or --version-name are specified, thesevalues will replace any value already in the manifest.

Separate libraries with ':'.--generate-dependenciesgenerate dependency files in the same directories for R.java and resource package--auto-add-overlayAutomatically add resources that are only in overlays.--preferred-densitySpecifies a preference for a particular density. Resources that do notmatch this density and have variants that are a closer match are removed.--splitBuilds a separate split APK for the configurations listed. This canbe loaded alongside the base APK at runtime.--feature-ofBuilds a split APK that is a feature of the apk specified here. Resourcesin the base APK can be referenced from the the feature APK.--feature-afterAn app can have multiple Feature Split APKs which must be totally ordered.If --feature-of is specified, this flag specifies which Feature Split APKcomes before this one. The first Feature Split APK should not defineanything here.--rename-manifest-packageRewrite the manifest so that its package name is the package namegiven here. Relative class names (for example .Foo) will bechanged to absolute names with the old package so that the codedoes not need to change.--rename-instrumentation-target-packageRewrite the manifest so that all of its instrumentationcomponents target the given package. Useful when used inconjunction with --rename-manifest-package to fix tests againsta package that has been renamed.--productSpecifies which variant to choose for strings that haveproduct variants--utf16changes default encoding for resources to UTF-16. Only useful when APIlevel is set to 7 or higher where the default encoding is UTF-8.--non-constant-idMake the resources ID non constant. This is required to make an R java classthat does not contain the final value but is used to make reusable compiledlibraries that need to access resources.--shared-libMake a shared library resource package that can be loaded by an applicationat runtime to access the libraries resources.
