Does anybody know how to keep a socket connection alive in an android app that is in the bakcground?
The app is for a handheld scanner that has a “gun” trigger that scanns a barcode that is sent to the app and to the socket (to the other side). So the app just needs to be alive in the background (could be hours) until somebody scannes a barcode that is picked up by the app and sent to the socket. The app needs to be in the background because there is another app needed in the forground.

Would I wrap (what code?) in a background service? Well I don’t quite know...
@jongleur1983 - I am waiting on upgrading my App from XF4.1 to 4.2 until the github issue - https://github.com/xamarin/Xamarin.Forms/issues/6907#issuecomment-523948279 is address
I am not sure why in XF 4.1 you are hitting that issue around Data_Triggers. Did you a github submit on Xamarin.Forms ?
they were pending approval: https://docs.microsoft.com/en-us/xamarin/xamarin-forms/release-notes/4.2/4.2.0-sr1
Hey guys, IDK if this is the right place to ask but I'm looking for the tech to use in my next project which is gonna be a mobile app that allows you to map land using the GPS, but I'm not 100% sure xamarin is the best choice although I'd really like to use C#. Besides obviously the GPS readings (preferably with low level access if possible), decent 2D rendering is also important ofc, I don't really need anything advanced, just basic shapes, text and images are fine, so I could use something simpler than skia. App size is also a concern though. Any input is appreciated.
It's gonna be opensource and nonprofit, I'm doing it to map some public parks here in Italy and then publish a digital map/guide app for the visitors to do and navigate effectively

@Alan-FGR you can absolutely do all of that in Xamarin and Xamarin.Forms. I know of several apps made with Xamarin.Forms that do almost exactly what you’ve described.
with the new Android App bundles and build optimizations, I hope app size is a concern of the past
Jean-Marie has some recent articles about drawing on maps https://www.sharpnado.com/
Xamarin Essentials gives you a lot of geolocation data https://docs.microsoft.com/en-us/xamarin/essentials/geolocation?context=xamarin%2Fandroid&tabs=android
and of course you can use 100% of the native platform apis in C#
jcmanke has been adding a lot of good Maps stuff. This one for drawing is coming in 4.3 in preview now and stable in just a few weeks. xamarin/Xamarin.Forms#6136
Hi all. Running into an issue with the Xamarin.Inspector on VS for Mac. It appears to try and start, but then just gets stuck "Waiting for Xamarin Inspector to connect to application..."
Working through the information in the docs. Linker setting is set to Don't Link, Simulator has network access, no log file is available at the path specified. There is no Inspector folder under
Anything else I am missing?

XCode on my Mac updated, and I can not build projects any longer. I am getting the above errata:
Suggestions?
New question: From the Xcode 11 release notes:
Xcode supports uploading apps from the Organizer window or from the command line with xcodebuild or xcrun altool. Application Loader is no longer included with Xcode. (29008875)
My App Store auto-updated XCode to the new version. How do I get this necessary feature back so I can perform an upload to the app store?
can someone take a look? I have always error code 202 "Session is invalidated unexpectedly" on DidInvalidate
thanks
@acaliaro did you see the Getting Started? (https://github.com/xamarin/ios-samples/tree/master/ios11/NFCTagReader#getting-started) you’ll need to enable it on the app provisioning profile in your Apple Developer account. Did you do that?
BTW, on MAC it works fine...
