Crash on adding an item to carouselView about carouselview HOT 11 CLOSED

I dont know how MyImages may look but they maybe a list of string representing the url of the image, dont?

Take a look how you are doing the binding of Image source, it should be something like this:

Also, if you are going to build an image carousel, use FFImageLoading or you will get OutOfMemory crash in Android.

from carouselview.

Image Source="{Binding .}"

from carouselview.

Take a look at this repo as example: https://github.com/alexrainman/TabbedCarouselView

from carouselview.

thanks for the prompt response ,
MyImages is an observableCollection

VehicleImages = new ObservableCollection();

i will have a look - weird part is I got it working for the first time and not anymore :)

from carouselview.

The plugin has been well tested by the community and lot of issues has been fixed and functionality added. The only trick with images is to use it with FFImageLoading.

from carouselview.

in your sample Source="{Binding .}" what is dot for?

hi @alexrainman

soi tried your suggestion with using the FFImageLoading and it only worked once. every other try throws the exception i posted before .

This is what i have done that is community visible:

• Alex has been pretty active sharing his knowledge and answering questions in StackOverflow, GitHub and Xamarin Forums.
• Alex has been open sourcing Xamarin components and plugin with the community, with more of 10 repositories being maintained on GitHub.
• One of Alex's Xamarin.Forms plugin, the CarouselView, is currently being pulled into the Xamarin.Forms core (xamarin/Xamarin.Forms#853). As an stable widget, this control has become the standard for Xamarin.Forms carousel screens with more that 16K downloads in NuGet and more than 100 solved and not open issues.
• Another Alex's plugin, the SegmentedControl (https://github.com/alexrainman/SegmentedControl), is a big candidate to be also pulled into Xamarin.Forms core.
• Plus Xamarin.Forms UI related plugins, Alex shares plugins to set app icon Badge, Google Analytics and KeyChain access.
• Alex shares his knowledge about cutting edge technologies like Couchbase NoSQL and MobileIron integration with Xamarin Apps.
