Hey!
I have a page with a barcode scanner in which another page is opened when a scan is completed. I use Navigation.PushAsync, which works everywhere in the app, but somehow it doesn't work here and throws the exception "Only the original thread that created a view hierarchy can touch its views". I have no idea how to fix this, so hopefully someone is able to help.
The interface:
Getting the scanned result and redirecting to the page (simplified):
Opening the page (simplified):
The error occurs at line 127. I hope someone can help!
Try
Device.BeginInvokeOnMainThread (async() => {
await Navigation.PushAsync...
});
Hey! This works, thanks!
Now I have several Navigation usages in the code, do I need to set this invoke for each and every one of them or is there one general code where they can all use this invoke?
No. You should use it only when you have to navigate but you are not in the main thread, so I think the barcode event is the only situation when you have to use it
Okay perfect, thanks again!
Hey! I do face a new problem for which I made a new question. Maybe you know the answer to this?
