玩转bundletool工具之获取aar包信息

一、前言

  bundletool是一个强大的aar包工具，可以对aar包生成apks集合，检测基础apk包大小等等，可参考：bundletool工具使用详解 一文。在本章节，将详细介绍一下如何使用bundletool工具，从aar中获取各种包信息。

二、使用 dump 命令获取aar包各种信息

2.1 关于 dump 命令

  可以使用 bundletool help dump 查看bundletool工具的 dump 命令的详细介绍，其中包含样例、信息来源分类以及命令选项，如下所示：

Description:
    Prints files or extract values from the bundle in a human-readable form.

    Examples:

    1. Prints the AndroidManifest.xml of the base module:
    $ bundletool dump manifest --bundle=/tmp/app.aab

    2. Prints the versionCode of the bundle of the base module:
    $ bundletool dump manifest --bundle=/tmp/app.aab --
    xpath=/manifest/@versionCode

    3. Prints all the resources present in the bundle:
    $ bundletool dump resources --bundle=/tmp/app.aab

    4. Prints a resource's configs from its resource ID:
    $ bundletool dump resources --bundle=/tmp/app.aab --resource=0x7f0e013a

    5. Prints a resource's configs and values from its resource type & name:
    $ bundletool dump resources --bundle=/tmp/app.aab --resource=drawable/icon
    --values

    6. Prints the content of the bundle configuration file:
    $ bundletool dump config --bundle=/tmp/app.aab

    7. Prints the content of the runtime-enabled SDK configuration file:
    $ bundletool dump runtime-enabled-sdk-config --bundle=/tmp/app.aab

Synopsis:
    bundletool dump <manifest|resources|config|runtime-enabled-sdk-config>
        --bundle=<app.aab>
        [--module=<base>]
        [--resource=<0x7f030001>]
        [--values]
        [--xpath=</manifest/@android:versionCode>]

Flags:
    --bundle: Path to the Android App Bundle.

    --module: (Optional) Name of the module to apply the dump for. Only applies
        when dumping the manifest. Defaults to 'base'.

    --resource: (Optional) Name or ID of the resource to lookup. Only applies
        when dumping resources. If a resource ID is provided, it can be
        specified either as a decimal or hexadecimal integer. If a resource name
        is provided, it must follow the format '<type>/<name>', e.g.
        'drawable/icon'

    --values: (Optional) When set, also prints the values of the resources.
        Defaults to false. Only applies when dumping the resources.

    --xpath: (Optional) XPath expression to extract the value of attributes from
        the XML file being dumped. Only applies when dumping the manifest.
