Calling startActivity() from outside of an Activity context requires the FLAG_ACTIVITY_NEW_TASK flag.

Set this flag

I'm just calling this Device.OpenUri("https://google.coom"); code from my view model.
How can I add that flag while calling Device.OpenUri?

in manifest file on your android project

May I recommend: https://github.com/xamarin/essentials and our browser API : ) it actually uses chrome custom tabs too :)

Looking at this code: https://github.com/xamarin/Xamarin.Forms/blob/793bbe6c850c73fab21db372b80e52521c97f82f/Xamarin.Forms.Platform.Android/Forms.cs

It should have ClearTop and NewTask if you are using an application context: https://github.com/xamarin/Essentials/blob/master/Xamarin.Essentials/Browser/Browser.android.cs#L28-L30

If it was an Activity then this wouldn't be the case.

I'm getting the same exception, when trying to open a website.

Keep calm and wait for merging the pull request

I've fixed that by using package that @jamesmontemagno provided.
