Is your feature request related to a problem? Please describe.
三星国行 ROM 中有一段叫 com.android.server.GmsAlarmManager 的代码(港行也有,但是通过开关禁用了),会检查 www.google.com 的连通性。在无法连接的情况下,会对 GMS 实施 3 个限制,包括只允许访问解析 checkin.gstatic.com 得到的 IP,推迟 alarm,限制 wakelock。可以在 adb shell 中执行 dumpsys alarm 输出的内容的尾部看到相关信息。

因此,在使用分应用代理的情况下,如果没有勾选 Android System,将会导致 Google 全系软件无法正常使用。而 Per-app VPN 在系统底层是 iptables 按 uid 转向流量,所以如果使用 bypass 模式时,也可能在排除其他 app 时无意将 Android System 排除掉。

Describe the solution you'd like
在分应用代理的设置界面,显式显示 Android System,并按 uid 同步选择状态。

Additional context
我稍后附上 PR。
