Crashes when app resumes

[johnsonwangnz]

First initialization is ok, but after that the same initialization call throws exception Unhandled Exception: System.TypeInitializationException: The type initializer for 'ConfigurationManager' threw an exception. occurred

@johnsonwangnz Hi, what is your platform that you test it? which version of PCLApp do you use?

[johnsonwangnz]

I ma using vs 2017, Android 7.1 -API 25 x86, the place initialization was done is in shared portable resources. I have not tried other platforms.

@johnsonwangnz what is your meaning about 'same initialization'? Did you mean call

ConfigurationManager.Initialise(assembly.GetManifestResourceStream("DemoApp.App.config")); twice?

If you prevent to reinitializing of ConfigurationManager, Did you have any problem in using ConfigurationManager after resuming app?

Please try this branch from nuget if you have same problem again, tell me please. :)

[johnsonwangnz]

Yes I put following code in App constructor in pcl Assembly assembly = typeof(App).GetTypeInfo().Assembly; ConfigurationManager.Initialise(assembly.GetManifestResourceStream("DemoApp.App.config"));
then every time app resumes, it will be executed again, the second line is where the exception is, I have implemented the reading of App.config into a property myself using similar idea, I only added a test to see if that property already loaded then no need to read again. So it might be just a check, Cheers

@johnsonwangnz : Probably you have a workaround by now or maybe you already have a fix for this. But just so that someone else can get some help out of this, try checking if you already have your namevalue collection loaded before you initialize. ex:

if(ConfigurationManager.AppSettings == null) ConfigurationManager.Initialise(assembly.GetManifestResourceStream("DemoApp.App.config"));

Hope this helps. :)

Thanks

Managed to recreate this. When I put in the null check, it stopped throwing at PCL App.cs level, and threw in MainActivity.cs at: LoadApplication(new App(new AndroidInitializer()));

[soroshsabz]

@AllFallD0wn Did you write ConfigurationManager.Initialise(PCLAppConfig.FileSystemStream.PortableStream.Current); before LoadApplication?

Did you see Usage of library?

[Nick-Case]

@soroshsabz I was following the usage for Embedded App.Config, not File System App.Config:

var a = typeof(App).GetTypeInfo().Assembly;
if (ConfigurationManager.AppSettings == null)
{
    ConfigurationManager.Initialise(a.GetManifestResourceStream("App.config"));
}

This resulted in the above exception when resuming the application

[phamthanhtong]

FOR FILE SYSTEM APP.CONFIG In MainActivity.cs if (ConfigurationManager.AppSettings == null) { ConfigurationManager.Initialise(PCLAppConfig.FileSystemStream.PortableStream.Current); }

[soroshsabz]

@Nick-Case Ok, Please share App.xaml.cs

thanks

Just try to change the BuildAction of the config file. Right click on the App.config > Properties > Build Action = Embedded resource

[soroshsabz]

@johnsonwangnz Did you problem is resolved?

[soroshsabz]

@johnsonwangnz Please close issue if your issue was resoled

thanks
