    How do I address this?
    Shane Neuville
    @PureWeen

    access the context from a static instance in android isn't recommended
    you should access the context from whatever context that text view is instantiated from

    you should be able to do this.Context

    if you can't do this.Context then you need to pass in the Context from whatever is calling the code to instantiate the TextView

    pm64
    @pm64
    Thanks @PureWeen! This code is actually in a custom renderer, so sounds like I need to update the interface.
    Do you happen to know the type of Context? Intellisense is saying it's a type that doesn't appear to exist, Xamarin.Forms.Context..?
    pm64
    @pm64
    The calling code is in a class that inherits from Grid, and there's no this.Context for me to pass..
    Shane Neuville
    @PureWeen

    can you post the whole class into a gist where this code exists?

    var textView = new TextView(Forms.Context);

    pm64
    @pm64
    @PureWeen sure, here you go:
    @PureWeen above is from the Android project .. the following is from the Xamarin.Forms project:
    And sorry, "custom renderer" was inaccurate. I meant "platform-specific implementation of a shared interface".
    Shane Neuville
    @PureWeen

    that's a tricky one :confused:

    I would use this plugin

    https://github.com/jamesmontemagno/CurrentActivityPlugin
    And retrieve the current Context from that

    Which should be fine

    technically what you should do is retrieve the Context from the renderer associated with the Grid but that will only matter if you're using material or if your Grid has a different activity context

    pm64
    @pm64
    So best, best practice would be to use CurrentActivityPlugin within the Grid to obtain the Context from the renderer associated with the Grid, then pass that Context to my method?
    Shane Neuville
    @PureWeen

    yea but that might be overkill :smile: it's hard to know from the scenario

    in theory the Context on the Grid is just going to be your FormsAppCompatActivity

    it would only change if for some reason you are instantiating a new context for some reason
    like a different themed context or something like that
    pm64
    @pm64
    Ok, I'll need to read up on that to better understand the implications.
    Thanks man! Much appreciated.
    Shane Neuville
    @PureWeen

    yea with android the styles/themes etc.. are all stored inside the context so that's what android native views use to know how to make themselves look a certain way

    So, for material what we do is instantiate a new Context with material themes and then that gets passed through to all the children which then style based on that new context

    What you could also do (which would probably be fine) is register the concrete type yourself in MainActivity

                PaintUtils utils = new PaintUtils(this);
                DependencyService.RegisterSingleton<ICalculateTextWidth>(utils);

    or you could even just register a static TextView

    Because you are only using it to measure you don't really need to instantiate a new one everytime

    pm64
    @pm64
    Ah yes, great point
    Hey @PureWeen while I've got your ear, let me run one more thing by you that's been bugging me for ages. When I build my Android project, I get these warnings:
    Found conflicts between different versions of "Microsoft.CSharp" that could not be resolved.
    Found conflicts between different versions of "System.Numerics.Vectors" that could not be resolved.
    This project is referencing all of the latest bits, but it's been updated over time and I'm thinking these warnings might relate to some lingering artifact from the past. But I'm not able to identify it. Any thoughts?
    Shane Neuville
    @PureWeen

    that one I'm not super sure

    Your best bet for an answer there would be to hop in here
    https://aka.ms/dotnet-discord

    And ask the android team...

    My guess there is that that's a conflict between the mono version of those and the .net version of those

    you might have a nuget pulling in net47 or something versions of those

    in your obj folder there's a file called project.assets.json that you MIGHT be able to mine through to find where those are coming from

    Hello, I’m trying to get more information in how to modify itemselected or item clicked event in a shell menu or tab menu. So I want to do more actions than just navigating to another page by clicking this menu tabs. I used to use Master details page and Xamarin Navigation Service with creating my own custom menu, but now I want to learn more about shell navigation and do the same.

    I am using ninject and linking all binding contexts of my pages with view models using this menu item selected event. Please if anybody have an example, how to use menu or tab itemselected event on Xamarin shell?

    @IoTFier I was told Discord is only for development of XF, not for developer community help...
    IoTFier
    @IoTFier
    Hello @TonyLugg, that's incorrect, please join #xamarin-forms channel of the DotNetEvolution server
    Shane Neuville
    @PureWeen

    that's actually mostly true

    ideally discord stays more contributor/developer focused

    And then this chat and forums/issues/so etc... are more focused around general help

    Hey, anyone here deving for watchOS ? I got a weird error:
    TMS-90484: Invalid WatchKit Support - The WatchKitSupport2 folder is missing. Rebuild your app using the current public (GM) version of Xcode and resubmit it.
    Don't know what else to update. Might be another error that is being messaged wrongly?

    hello! new to the xamarin scene.
    I heard that Xamarin now supports linux as a build target! If it's true, could someone give me instructions on how to do this on linux?
    Matthijs ter Woord
    @mterwoord
    I'm tring to build my Xamarin Forms Android target project on a build server (self-hosted). Some builds fail due to resources not being found (or picked up) resulting in 'Resource.Layout' does not contain a definition for 'Tabbar' errors. Rerunning the same build (on same git commit) fixes it. Am I missing something here?
