设置代理

adb shell settings put global http_proxy 代理IP地址:端口号
如:
adb shell settings put global http_proxy 127.0.0.1:8888

取消代理

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

移除代理后要重启手机才能生效。设置代理可以多次设置，立即生效
