Another great video. Thank you very much for the awesome job you're doing. The location "Bug" seams to be because of the GetLastKnownLocationAsync() call. It basically gets the cached location every time you tap. If I use another emulator where I set the location before I tap the button then it finds another monkey. If I comment out that line then it finds different monkeys as I change my location.
Great Video Gerald, however the ICommand attribute seems to have disappeared from the CommunityToolkit.Mvvm 8.2.2 , and I can't remember this concept being introduced in any of the previous videos in this crash course. Is there a video I've missed showing how to integrate the ICommand attribute and use commanding to implement navigation using MvvmCommunityToolkit 8.2.2.?
Yeah it was a bit unfortunate that they introduced breaking changes right after these videos. Sorry about that! The repository associated with the course is updated with the latest bits. I’m planning to make some more dedicated content about the MVVM stuff. Would that be useful?
@@jfversluis You have obviously put in a tremendous amount of work into these crash course .Net Maui videos, it seems a shame not for them to be kept up to date with the latest 'developments' by the Microsoft / MVVMCommunityToolkit team. I wonder if there is an easy way to keep these updated than having to redo the video.
@stevehutch appreciate it thank you! Yeah it would be cool to at least add some kind of annotation to the video later but alas. No such luck. Life of a UA-camr 😄
My guess on the geo-location not refreshing is the line of code that checks for a cached geolocation. override that and it should get the new location.
Thanks for explaining it Gerald. Any chance for functionality that would automatically notify application when location has changed? I assume that constant checking for location changes may drain battery quicker than subscribing to location changes instead. This functionality was available in Xamarin.Forms, not sure how to do it in MAUI
I don't think that functionality was inside of the box for Xamarin.Forms. Surely it is possible, if it was through a plugin that make sure that it has been made compatible with .NET MAUI. If that hasn't happened yet, it probably will soon. Or, of course, you can implement it yourself with platform code!
I forced my location to Seattle, Wa. and the app returned the nearest monkey which was in Seattle. So the code works. I believe the default location for Windows desktop is San Jose, Ca. The would make the monkey in Phoenix the closest.
At 23:20 it shows as blank because the location is in the middle of nowhere. This caught me out. Change the map from Default to Satellite and you'll be able to see where it is.
Another ver useful video on Maui. I have to download images from a Http(not s) website. I need to add User-Agent and Accept default request headers for each request. To use UriImageSource in Xaml to download the images, I need to add these request headers for these requests. Is it possible for me to setup an http client with these headers and use dependency injection to provide this http client for all UriImageSource requests?
That is a very good question! For the HTTP part (try to get around that!) you will have to add something to your AndroidManifest and info.plist to allow iOS and Android to even do that. For the rest, I had a quick look at the source, it seems to use it's own HttpClient 😩 github.com/dotnet/maui/blob/cdf43dafaf2dd30ec8732adcb4df855465e9623f/src/Controls/src/Core/UriImageSource.cs#L116 So either write your own image source for now and it would probably be worth to open an issue for this and see if we can change that somehow.
@@jfversluis I have it all working in a Xamarin Forms app. I download and cache the images. I have been hoping since the UriImageSource and its caching became available that there would be a method of providing default request headers for the system requests. However recently icarrenomercado had suggested using : ImageHandler.Mapper.AppendToMapping(nameof(ImageView.Drawable), async (handler, view). I have been playing with this but havent been able to get it working yet.
@@davefoley5071 it has been requested a couple times more. I guess it would be cool if you could configure an HttpClient that would be used throughout so you can configure your headers and such once and it will be picked up by our code as well If you have something that works or ideas open that issue and/or pr!
[ICommand] no longer works. I had to do some Google-Fu and found out that [ICommand] was renamed to [RelayCommand] in the CommunityToolkit.Mvvm package starting with 8.0.0 preview4 and carrying over to the main 8.0.0 release.
Yeah it’s unfortunate they did a breaking change rename soon after 😢 the attached repository for the videos have the updates code though. Thanks for sharing!
Not sure how I missed this great video! 🙂Is there a way in a MAUI app to Click a Button which would open the phones camera and take a picture and store that image in a DB or Blob Storage?
Yep absolutely! Combine it with this (MediaPicker is now built in to .NET MAUI, it’s under a different namespace though) ua-cam.com/video/AYfGxhEHiec/v-deo.html And this: ua-cam.com/video/KPDGtLeNClQ/v-deo.html and this: ua-cam.com/video/5fJZQcukagk/v-deo.html I see I need to make a combined updated video 😄
Are all essentials features available yet in Maui, can we track development of this somewhere? await MediaPicker.CapturePhotoAsync() always returns null. Permissions are set correct.
Remember that if you’re running on an emulator that is no longer local host. It’s treated as a separate device so always use your IP address of the machine the API is running on
@@jfversluis thanks for tip! I figured that part out and am now stuck with either a certificate error if i try on https or an ''unexpected end of stream'' error, and I've spent a full 3 days trying to get passed them. It seems using AndroidClientHandler might solve the problem but that's in a deprecated Xamarin library and so not included in MAUI...
In the documentation they mentioned that in Android we should add the code in Platforms/Android/MainApplication.cs you add it to AssemblyInfo and it works
@@jfversluis thank you for your reply... I have another question can we now use maui in production apps? Also I didn't find the push notifications in the documentation, how to add it to the app?
@@baseljuma158 we’ve released it as GA. If you feel comfortable using it in production is up to you! There might be some third-party plugins that do not have support yet. So be sure to check out what you need first. Push notifications is definitely possible but I don’t think there is any content for it yet.
Gerald, can u make a Speech to Text video for Maui? For XF u can use Azure Service or Google's API but u have to pay for Azure and Google's API is hard (impossible? ) to customize for XF. Compared to other frameworks it is very poor to be honest. Would be awesome! Best Rob

Yes the map works on Windows. Sometimes it is zoomed in. So if there are nothing of interest nearby, it looks blank and you have to zoom out.
Ah that makes sense I guess! It’s just zoomed in very much then. I’ll have to try thanks 😄
