有这么一个需求，需要给手机设置全局代理。百度到的结果都是设置后，如果需要清除代理的话，需要重启手机，这里使用的方式是不需要重启的方式后
实现方式如下：
设置代理:
String[] strings = {"settings put global http_proxy " + ip + ":" + port};
ShellUtils.CommandResult commandResult2 = ShellUtils.execCmd(strings, false, true);直接使用adb shell命令设置，需要权限
<uses-permission android:name="android.permission.ACCESS_CONTENT_PROVIDERS_EXTERNALLY" />
<uses-permission android:name="android.permission.WRITE_SECURE_SETTINGS" />使用该权限时，需要给应用系统签名
清除代理：
String[] strings = {"settings put global http_proxy :0"};
ShellUtils.CommandResult commandResult2 = ShellUtils.execCmd(strings, false, true);
附上shellutiils代码
