Controlling Image Caching in Xamarin.Forms & .NET MAUI

[@abaal2109]

In xaml if you set the cache validity to 0:1:0 it will do it for 1 minute.

🤯🤯🤯 I knew someone would know how to do it! I’ll try it out. I searched for like an hour with no success

I appreciate the videos that you are creating in this series. These videos are helping me build my own app as I teach myself.

[@ap00rva]

Thanks for the example. One thing that we are struggling in Maui is that the Image Url that we have is protected and we have to provide an Authorization bearer token, so is there a way to inject the HTTP header and put the Authorization token? This is specifically for Android.

Nice to know this. Thanks James!

Could you explain about a listview with images from local storage?

[@wilddy88]

Hello James, great video as usual. Is there a way to check if the image is loaded correctly? So that we can change to a placeholder image if the load fails ?

Is there a way to improve local image loading ? Since we are on MAUI and can't use FFImageLoading, there are small lags when displaying local image in collectionview

[@JamesMontemagno]

Have you looked at t.co/73i5Haumr3 also there is a new ffimageloading as well I think github.com/Redth/FFImageLoading

@@JamesMontemagno our main performance issue is on Android, image displaying is not as smooth as xamarin. we are still looking for an improvement.

[@Mielesplayz]

thanks, I didn't know you can just simply disable caching from an image
(I have a profile picture system, but it kept loading previous images because of the cache)

[@NavneetKeyIdeas]

Is there any way to clear the image cache if the image changed in url?

[@fanyang1972]

What if the image is stored locally; and can be taken?

[@fanyang1972]

figured out: replacing ImageSource.FromFile( localFile) with
var byteArray = File.ReadAllBytes(localFile); ImageSource.FromStream(() => new MemoryStream(byteArray))

Hi James thanks for the great video. What I want to know is, what if you want to cache the Image for a feew days but still be able to allow the user to update it before the cache experation date? cause the Image does not update if still cached even on property changed. and I don't think it's optimal to diable cache

[@JamesMontemagno]

Not that I know of off the top of my mind. What you may be able to do is create the image with the normal cache days but when you refresh manually then turn off caching in that instance and then put it back later
