我正在尝试建立基石基于 AOSP 4.3_r2.2。我在构建过程中遇到了很多错误，如下所示：
frameworks/base/core/res/res/values/public.xml:244: error: Symbol 'config_bluetooth_adapter_quick_switch' declared with <java-symbol> not defined

我在这里搜索并找到了这个issue。所以我知道这可能缺少符号定义问题。但是当我查看 public.xml 时，我发现它们属于不同的类型，如下所示：
<java-symbol type="bool" name="config_bluetooth_sco_off_call" />
<java-symbol type="bool" name="config_enableDreams" />
<java-symbol type="drawable" name="ic_suggestions_add" />
<java-symbol type="drawable" name="ic_suggestions_delete" />
<java-symbol type="id" name="backspace" />
<java-symbol type="id" name="carrier" />
<java-symbol type="id" name="dangerous_perms_list" />
...
我还发现框架/base/core/res/MakeJavaSymbols.sed 有一个脚本文件，它说命令
make framework 2>&1 | sed -n -f MakeJavaSymbols.sed | sort -u
可用于生成缺失的资源。我搜索了很多，我找到的只是运行这个命令，它会输出丢失的部分。但我跑了，什么也没发生。所以我的问题是我应该在哪里以及如何添加这些缺失的符号？有几百个，需要手动添加吗？我错过了什么吗？由于我是 AOSP 框架的新手，所以请帮助。
最终解决了这个问题，通过这样做：
1.删除了public.xml中的符号定义；
2. 将 android.view.Surface 替换为 android.view.SurfaceControl，将 WindowManagerService.DEFAULT_DIM_DURATION 替换为 WindowAnimator.DEFAULT_DIM_DURATION。
之后我就编译成功了，并且可以运行，虽然还是有一些问题。
