Android 7.1.2 - System.ObjectDisposedException: Cannot access a disposed object.

I’m using Rg.Plugins.Popup in my Xamarin.Forms app.

Per not, I haven’t much issues with Android (there are some on iOS), but today I had exception, that I’m no able to reproduce again.

However the stacktrace might be helpful to find the root cause:

I am getting this error with latest version.

My popup contains an Editor control which would be focused at time of closing popup.

Which leads me to believe it must be caused by something around this line:

I believe I am seeing the same issue. It happens on a variety of devices and OS versions. I’m using 1.1.4.154-pre, and I didn’t see this issue prior to the update (previously using 1.0.4)
