Error on view in tab

[Zainal Arifin]

Dear Synfusion,

I'm using Carousel to show my image which is taken by camera.

I got this error when view the carrousel object.

Java.Lang.NullPointerException: Attempt to invoke virtual method 'int android.graphics.Bitmap.getWidth()' on a null object reference

I attach pic for my layout to view the carrousel and class fo my carrousel.

Where I can set the height / width to view the carrousel ?

Thanks

best Regards,

Afin

Hi Afin,

Thanks for contacting Syncfusion Support.

On checking your code provided, it is found that the images are assigned to SfCarouselItem's ImageName API from custom Directories. Currently in Carousel, it is required to include the images in the Project drawable folder and need to assign the image name to the SfCarouselItem's ImageName property.


path: ../Resource/Drawable

We are glad to let you know that in our latest Volume 2 2016 release we have provided support for having Custom View in which we can have Images from any custom source and it can be assigned to SfCarouselItem's ContentView property API.

Please upgrade to our latest Syncfusion version to have this feature and below is the download link for upgrading the Syncfusion version.

Dear Hemalatha,

Is there any restriction for filename ? My path to view the image in carrousel is like below.

"/storage/emulated/0/Pictures/2131230793a8f5466d-cf27-e611-80c1-0a0027000000/IMGAFFOGATO_1.jpg"

My carrouse still don't show up even my item collection has saved well.

Best Regards,

Afin

Hi Afin,

Thanks for your update.

In SfCarousel control, SfCarouselItem.ImageName can be used only if the images are provided in the Project Resources folder. In order to achieve your requirement by placing the images in device location or from any url please make use of SfCarousel's Template support. We have created a sample for using Template support in SfCarousel control.Please download the same from the following link

Link: ExampleProject

Please check the sample and if the issue still persists, update us the modified sample or the replication procedure to analyze further and provide the solution.

Hi Hemalatha,

Please advise

Dear Hemalatha,

I tried to modify the list into like below.

list.Add(new MyPage("/storage/emulated/0/Pictures/2131230793/a8f5466dcf27e61180c10a0027000000/IMGAFFOGATO_000011.jpg"));

            list.Add(new MyPage("/storage/emulated/0/Pictures/2131230793/a8f5466dcf27e61180c10a0027000000/IMGAFFOGATO_000012.jpg"));

            list.Add(new MyPage("/storage/emulated/0/Pictures/2131230793/a8f5466dcf27e61180c10a0027000000/IMGAFFOGATO_000013.jpg"));

Hi Afin,

We were unable to reproduce the reported issue at our end. We have placed an image in the below sdcard location for testing purpose and provided the location to the Image's Source property and we got the image loaded to the Carousel control. Please refer the following code example and screenshot

Image Location : /sdcard/Downloads/image1.jpg

Code Example: 

  

public List<MyPage> GetDataSource()
{
List<MyPage> list = new List<MyPage>();

list.Add(new MyPage("/sdcard/Downloads/image1.jpg"));
list.Add(new MyPage("/sdcard/Downloads/image1.jpg"));
list.Add(new MyPage("/sdcard/Downloads/image1.jpg"));
return list;
}

Please update the replication procedure or video to analyze further regarding the reported behavior.
