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 systemfonts 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





   
        en-US
        zh-Hans-CN
        zh-Hans-HK
        zh-Hans-MO
        zh-Hans-SG
        zh-Hant-HK
        zh-Hant-MO
        zh-Hant-TW
   





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
