Xamarin Forms Image Not Showing

Post a Comment
I have a Xamarin Forms (2.0) Android app where I'm trying to show an image. I've got an icon called icon-pages-r1.png which I'm trying to show using the following code:

Solution 1:

You can't use hyphens in image names for Xamarin Android. Get rid of the hyphens (in both the file name and the Image reference) and you'll be set.

Solution 2:

For others who may end up here...

Make sure the image file is actually a part of the project (Resources\drawable) and that the build action is AndroidResource.

Solution 3:

When binding to the name of an image resource in android I found it must be:

  • in Resources/Drawable folder
  • set Build Action: AndroidResource
  • set Copy to Output: Do not copy
  • doesn't allow hyphens in name
  • name is case sensitive

Solution 4:

I had this issue.I set MSBuild project build output verbosity as Diagnostic. Now I found the following in my Output window when I searched for OOM.

ImageRenderer: Error loading image: Java.Lang.OutOfMemoryError: Failed to allocate a 571513228 byte allocation with 2140744 free bytes and 92MB until OOM

Now tried

  • Create a png image which has less than 200KB size and less than 1400 X 1050 size (for testing purpose).

It worked fine.

Note: "MSBuild project build output verbosity" can be found under Tools -> Options -> Projects and Solutions -> Build and Run

General Checkpoints

  • Read Local Images
  • Make sure the file name has only lowercase alphabets.
  • Add that png file into Resources/drawable folder.

Create a content page as follows

<StackLayoutVerticalOptions="Center"HorizontalOptions="Center"><LabelText="Pre" /><ImageSource="abstracttriangleg.png"Aspect="AspectFill"VerticalOptions="End"HorizontalOptions="CenterAndExpand"/><LabelText="Post" /></StackLayout>
  • Clean solution.
  • Clean bin and Obj files.

Resources says:

Android supports bitmap files in three formats: .png (preferred), .jpg (acceptable), .gif (discouraged).

Compress PNG and JPEG files says:

You can reduce PNG file sizes without losing image quality using tools like pngcrush, pngquant, or zopflipng. All of these tools can reduce PNG file size while preserving the perceptive image quality.

The pngcrush tool is particularly effective.

To compress JPEG files, you can use tools like packJPG and guetzli.

Solution 5:

For iOS

Step 1: Add your image into ios -> Resources folder (If not create it)

Step 2; Right click image -> Properties -> Build action -> set as "Content"
