I'm looking to set a global Proxy Pac URL on Android.
I tried with adb shell settings put global proxy_pac_url however it seems Android does not handle this, even though it seems to be specified: http://androidxref.com/8.1.0_r33/xref/frameworks/base/services/core/java/com/android/server/ConnectivityService.java#3234
Setting global http_proxy does work, but the disadvantage is that the only way to unset the proxy settings is to reboot the device.
