Question

How should I use it on release mode for xamarin forms?

Opened this issue 7 years ago · 5 comments

Hello,
I have Xamarin forms app and It works perfectly on debug mode. But when I build of release mode, I receive a exception of concurrency. I'm using a ConcurrentBag in order to save RemoteSystem but it crashes when add ítems. How should I do it in order to save ítems in a list?
Thank you

@cansado2930 can you please provide a snippet of your code and where the problem is?

Hi @cmknox
Yes, without problems. This is the code:

private static ObservableCollection deviceList = new ObservableCollection();
private static RemoteSystemWatcher _remoteSystemWatcher;
//....//
private static void searchdevices()
{
_remoteSystemWatcher = RemoteSystem.CreateWatcher();
// Subscribing to the event that will be raised when a new remote system is found by the watcher.
_remoteSystemWatcher.RemoteSystemAdded += RemoteSystemWatcher_RemoteSystemAdded;
// Start the watcher.
_remoteSystemWatcher.Start();
}
private static async void RemoteSystemWatcher_RemoteSystemAdded(RemoteSystemWatcher sender, RemoteSystemAddedEventArgs args)
{
try
{
deviceList.Add(args.P0);
}
catch (Exception) { }
}
//....//

As you can see, I call to searchDevices in order to actívate the searcher. The RemoteSystemWatcher_RemoteSystemAdded function, on the line "deviceList.add(args.P0)" is the "problem". On debug mode, as App run slow it Works correctly but when It is built on release mode
then app crash in this line, with a message of concurrency problem that I have been able to check on log. Do you have some advice in order to avoid this problem and save devices on a list.
Thank you!

@cansado2930 thanks for the reply. We are currently working on a new release for Xamarin that should address your problem. Stay tuned for later this week.

@cansado2930 we have released a new Xamarin SDK drop, 0.8.0, can you please give it a try and let me know if it works for you?

Answer 5 · 2017-11-29T17:52:24.000Z

Yes, I can. I have updated to 0.8.0 and I have built the reléase versión (because the debug with 0.8. Works correctly) and it crash again. I have attached the console log:
