字体相关介绍可参考

Android系统字体加载流程

Android 系统字体

10.0 和之前低版本还是有些差异的，可以查看编译 out 目录下 system\fonts 中所编译的字体文件

注释 frameworks/base/data/fonts/fonts.xml 中成对字体组

注释 external/noto-fonts/Android.mk 中不需要编译字体文件 .ttf .otf

删除无用语言包

frameworks/base/core/res/res/values/locale_config.xml

删除其中不需要语音列表，注意以为一组，这里只保留了中文相关

<resources>

    <string-array translatable="false" name="supported_locales">
        <item>en-US</item> <!-- English (United States) -->
        <item>zh-Hans-CN</item> <!-- Chinese (Simplified, China) -->
        <item>zh-Hans-HK</item> <!-- Chinese (Simplified, Hong Kong) -->
        <item>zh-Hans-MO</item> <!-- Chinese (Simplified, Macau) -->
        <item>zh-Hans-SG</item> <!-- Chinese (Simplified, Singapore) -->
        <item>zh-Hant-HK</item> <!-- Chinese (Traditional, Hong Kong) -->
        <item>zh-Hant-MO</item> <!-- Chinese (Traditional, Macau) -->
        <item>zh-Hant-TW</item> <!-- Chinese (Traditional, Taiwan) -->
    </string-array>

</resources>

这样修改后只是系统设置中系统–语音和输入法–语音–添加语音列表中只展示中文相关，

对应的资源文件并未删除依旧打包到了 system.img 中，依旧占用系统空间。接下来继续删除

frameworks/base/core/res/res/ 多余的资源文件夹，和刚刚的 locale_config.xml 保留对应
