使用 xamarin.forms.android 检测屏幕镜像

Question

I want to detect android screen mirroring to pc. I am currently coding in c# Xamarin Forms Android .

What I have done

Here someone recommended to use DisplayManager and VirtualDisplay documentation. But I don't know how to achieve that in code.

Here someone recommended to check DisplayManager.getDisplays(), and see if it's >1. Again not working to detect vysor I tried with code.

Answer 1

It is not possible to do so in Android.

Reference

The closest you could get is by using FlagSecure to prevent screenshots.

Answer 2

Finally I got the working answer.
Android mirrors like vysor can't mirror without having developer options enabled.
To check whether mirror can be run, check this code below:

//https://stackoverflow.com/a/31582092/11390822

var context = Android.App.Application.Context;
var resolver = context.ApplicationContext.ContentResolver;
if (Settings.Secure.GetInt(resolver, Settings.Global.DevelopmentSettingsEnabled, 0) == 1)
{
//Developer options enabled
//Mean vysor can mirror
}
else
{
//Developer options disabled
//Mean vysor can't mirror now
}
