查看AAPT命令格式

看到这里，有很多开发者可能会问：笔者是如何记得这么多的指令和它们的参数的？答案就是——其实笔者也不记得。

那么笔者是如何获取这些指令的使用方法的呢？相信经常使用Linux系统的开发者应该很清楚，通常终端程序都会有帮助，AAPT工具同样是这样。在终端下直接执行./aapt指令就可以获取所有的使用方法，显示结果如下所示。

  85.    -0  specifies an additional extension for which such files will not 
  86.        be stored compressed in the .apk.  An empty string means to not

  99.        inserts android:targetSdkVersion in to manifest. 
  100.    --max-res-version 
  101.        ignores versioned resource directories above the given value.

  108.    --replace-version 
  109.        If --version-code and/or --version-name are specified, these 
  110.        values will replace any value already in the manifest. By 
  111.        default, nothing is changed if the manifest already defines 
  112.        these attributes. 
  113.    --custom-package 
  114.        generates R.java into a different package. 
  115.    --extra-packages

  119.    --auto-add-overlay 
  120.        Automatically add resources that are only in overlays. 
  121.    --preferred-density 
  122.        Specifies a preference for a particular density. Resources that do not 
  123.        match this density and have variants that are a closer match are removed. 
  124.    --split 
  125.        Builds a separate split APK for the configurations listed. This can 
  126.        be loaded alongside the base APK at runtime. 
  127.    --feature-of 
  128.        Builds a split APK that is a feature of the apk specified here. Resources 
  129.        in the base APK can be referenced from the the feature APK. 
  130.    --feature-after 
  131.        An app can have multiple Feature Split APKs which must be totally ordered. 
  132.        If --feature-of is specified, this flag specifies which Feature Split APK 
  133.        comes before this one. The first Feature Split APK should not define 
  134.        anything here. 
  135.    --rename-manifest-package 
  136.        Rewrite the manifest so that its package name is the package name 
  137.        given here.  Relative class names (for example .Foo) will be 
  138.        changed to absolute names with the old package so that the code 
  139.        does not need to change. 
  140.    --rename-instrumentation-target-package 
  141.        Rewrite the manifest so that all of its instrumentation 
  142.        components target the given package.  Useful when used in 
  143.        conjunction with --rename-manifest-package to fix tests against 
  144.        a package that has been renamed. 
  145.    --product 
  146.        Specifies which variant to choose for strings that have 
  147.        product variants 
  148.    --utf16 
  149.        changes default encoding for resources to UTF-16.  Only useful when API 
  150.        level is set to 7 or higher where the default encoding is UTF-8. 
  151.    --non-constant-id 
  152.        Make the resources ID non constant. This is required to make an R java class 
  153.        that does not contain the final value but is used to make reusable compiled 
  154.        libraries that need to access resources. 
  155.    --shared-lib 
  156.        Make a shared library resource package that can be loaded by an application 
  157.        at runtime to access the libraries resources. Implies --non-constant-id. 
  158.    --error-on-failed-insert 
  159.        Forces aapt to return an error if it fails to insert values into the manifest 
  160.        with --debug-mode, --min-sdk-version, --target-sdk-version --version-code 
  161.        and --version-name. 
  162.        Insertion typically fails if the manifest already defines the attribute. 
  163.    --error-on-missing-config-entry 
  164.        Forces aapt to return an error if it fails to find an entry for a configuration. 
  165.    --output-text-symbols 
  166.        Generates a text file containing the resource symbols of the R class in the 
  167.        specified folder. 
  168.    --ignore-assets 
  169.        Assets to be ignored. Default pattern is: 
  170.        !.svn:!.git:!.ds_store:!*.scc:.*:<dir>_*:!CVS:!thumbs.db:!picasa.ini:!*~ 
  171.    --skip-symbols-without-default-localization 
  172.        Prevents symbols from being generated for strings that do not have a default 
  173.        localization 
  174.    --no-version-vectors   
  175.        Do not automatically generate versioned copies of vector XML resources.

这份文档解释了AAPT所能够使用的各种指令。如果开发者在使用过程中不记得某些指令的参数或者使用方法，那么直接使用这个指令就可以获取到你想要的内容了。
