删除全局 http_proxy 而不重启 Android 设备

Question

我使用以下代码通过命令行工具 adb 设置 Android HTTP 代理。

adb shell settings put global http_proxy <ip>:<port>

但是，当我想撤消代理设置时，以下代码不会删除代理。尽管清除了这些系统属性，Android 设备仍会尝试连接<ip>:<port>

adb shell settings delete global http_proxy
adb shell settings delete global global_http_proxy_host
adb shell settings delete global global_http_proxy_port

我必须重新启动 Android 设备才能删除代理。有没有办法在不重启设备的情况下清理代理？

安卓版本是7.0。

要重现此问题：

# Set up a proxy
adb shell settings put global http_proxy <ip>:<port>

# Remove them
adb shell settings delete global http_proxy
adb shell settings delete global global_http_proxy_host
adb shell settings delete global global_http_proxy_port

# Then open a browser, it will still connect to the proxy ip and port
