Carousel issue - Canvas: trying to use a recycled bitmap android.graphics.Bitmap #10032

mehrdadab · 2022-09-10T07:31:34Z

Description

I am using CarouselView in .Net Maui, I have four image Urls that I assign to an Image component inside a CarouselView, my code is as below:

       <CarouselView ItemsSource="{Binding CatList}" IndicatorView="indicatorView" CurrentItemChangedCommand="{Binding CarouselImageChanged}" >
            <CarouselView.ItemTemplate>
                <DataTemplate>
                    <VerticalStackLayout MinimumHeightRequest="250" MaximumHeightRequest="300" Margin="0,0,0,5" Padding="1">
                        <Image Source="{Binding ImageUrl}"  />
                    </VerticalStackLayout>

                </DataTemplate>
            </CarouselView.ItemTemplate>

        </CarouselView>
        <IndicatorView x:Name="indicatorView"
                   IndicatorColor="LightGray"
                   SelectedIndicatorColor="DarkGray"
                   HorizontalOptions="Center" />

In the first round, when I slide through images, it works perfectly but crashes in the second round after the first or second image.
When I debug, it shows the exception below:
Java.Lang.RuntimeException: 'Canvas: trying to use a recycled bitmap android.graphics.Bitmap@bb33eb5'

My images are large and if I resize them the issue may be resolved, but I believe it should be a way to disable recycling images, in case there is no way to resize them.

Steps to Reproduce

Create a .net Maui app
Create a Page with CarouselView and an Image Component inside it.
Bind a list that contains image URLs(to be assigned to the Image source) to CarouselView(The images must be large)
Run the application on an android device and swipe the images,
On the second round it crashes and the exception is Java.Lang.RuntimeException: 'Canvas: trying to use a recycled bitmap android.graphics.Bitmap@bb33eb5'

Link to public reproduction project repository

Version with bug

6.0.400

Last version that worked well

Unknown/Other

Affected platforms

Android

Affected platform versions

Android Version 9 - API 28, Emulator Android 11.0 API 30

Did you find any workaround?

I noticed if I add CurrentItemChangedCommand to the CarouselView it will happen later on Emulator(Sometimes at the third round)

Relevant log output

No response

I found out this issue happens only in Debug mode. It works fine in Release mode.

PureWeen · 2022-09-14T18:25:59Z

@mattleibow @rmarinho any additional thoughts?

mattleibow · 2022-09-15T11:57:17Z

I wonder if we just need to stop explicitly disposing images and let glide do it for us. In the image source service, we probably need to dispose when we are returning bitmap/drawable, but do nothing when loading into an image view.

jsuarezruiz · 2022-10-03T12:25:43Z

Could you attach a small sample where reproduce the issue?

nk54 · 2022-10-07T10:00:40Z

Same issue on Android (it works in Windows the first time only : if I go from last image to first image again, nothing happens anymore). I try to switch the background image of a page. Each second, I change the image.

Here is some basic code to reproduce the bug : on MainPage.xaml.cs
private readonly string[] _images = new string[3];
private int _index = 0;
private string _splashSource;
public string SplashSource
{
get => _splashSource;
set => Set(ref _splashSource, value); // you can set _splashSource and raise INPC here to replace Set
}
public async Task CarouselAsync(int index)
{
await Task.Delay(1000);
_index = index == _images.Length ? 0 : index;
SplashSource = _images[index];
await CarouselAsync(_index + 1);
}

And in MainPage.xaml :
<Image Aspect="AspectFill" Source="{Binding SplashSource}" />

I get the same using a CarouselView with an Image in the ItemTemplate. Android 13 with .NET 7 GA tooling.

Java.Lang.RuntimeException: 'Canvas: trying to use a recycled bitmap android.graphics.Bitmap@83fdbc8'

Here is a repro. Just scroll and scroll until it eventually happens. Usually not very long.

Same Issue here in CollectionView
Java.Lang.RuntimeException: 'Canvas: trying to use a recycled bitmap android.graphics.Bitmap@44625eb'

AmSmart · 2022-11-18T22:30:30Z

Yep, just experienced the same issue with the CollectionView on Android. Any workarounds for now?

terraslate · 2022-11-21T15:42:07Z

I found out this issue happens only in Debug mode. It works fine in Release mode.

For me it occurs in release mode.

terraslate · 2022-11-21T15:44:38Z

perhaps this helps

#11519

Unfortunately this bug is so unpredictable in the current implementation we cannot release anything on maui to the public. it could blow up on any device at any time as we've seen on our test devices. Regards

FM1973 · 2022-11-22T08:24:36Z

same here. we are about to release the app to public, but we can´t. The error randomly happens. This is really a show stopper!

FM1973 · 2022-11-22T16:04:31Z

This happens for CarouselView and CollectionView.
We got our app ready and it´s pretty stable except this bug (99% of crash reports).
Can someone tell me if there is a workaround? A custom image control for example?
Our customer is getting nervous and so do I.

I forgot: in my case this happens primarily in release mode.

Hope this helps to nail down the problem

angelru · 2022-11-25T15:16:02Z

The same issue...

terraslate · 2022-11-26T04:42:33Z

Hope the team get the importance of this. It's a fundamental building block of all these views that images are handled correctly as a base requirement, there cannot be any room for error otherwise your app will just crash and along with it your brand image. Without this it is not possible to release any Maui app at this time unfortunately. Luckily mine was a port from Xamarin, so I've reworked the changes back into the old app that the Maui port was going to replace and will revisit in another 3 to 6 months time to see if things have improved. Incidentally the performance of the scrolling in the Maui app also would not have let us release either, but that is a different topic.

1357310795 · 2022-11-26T12:24:45Z

Not only CarouselView, but the Microsoft.Maui.Controls.Image control will produce this error on switching ImageSource😓

FM1973 · 2022-11-26T12:26:34Z

@1357310795
Yes, I can confirm that.

AmSmart · 2022-11-28T13:42:15Z

@jsuarezruiz @mattleibow

This might need retagging. It looks as though it is unrelated to the CollectionView or CarouselView but happens in the Image control when the source is being switched.

This obviously will impact any Android Control that uses the RecyclerView under the hood (I believe this includes both CollectionView and CarouselView), since that will likely attempt to reuse the same Image Control while switching the sources as a user scrolls.

angelru · 2022-11-28T20:40:42Z

I don't know if it has something to do with it, but with CollectionView with images, when you scroll quickly it seems that the source of the images is exchanged.

angelru · 2022-11-30T08:33:57Z

any solution to 'Canvas: trying to use a recycled bitmap android.graphics.Bitmap@5601f7b' ?

mohachouch · 2022-11-30T13:30:10Z

@jsuarezruiz @mattleibow @PureWeen @hartez @davidortinau @maddymontaquila

This bug has been declared multiple times and the first time in June 2022.

https://github.com/dotnet/maui/issues?q=is%3Aissue+is%3Aopen+Canvas%3A+trying+to+use+a+recycled+bitmap

When do you plan to fix it. The bug is rated high but no one is taking care of it. How do you expect us to trust Maui if the same Xamarin Forms slow fix issues happen again. As part of my company we are seriously considering moving to another technology (native or flutter). We're tired of always having to find workarounds !

mohachouch · 2022-12-01T08:56:00Z

I spent a few hours to analyze this problem.

This bug was created following this pull request: #7348

While waiting for Microsoft to permanently fix this bug, the workaround consists of redoing the clear before each source image change.

Below is an example of code to add the clear in the source image mapping.

This workaround is applicable to the following bug
#11519 #11130 #10032 #9712 #8809 #9011
#8178 #8809

using Microsoft.Maui.Handlers;
using Microsoft.Maui.Platform;

namespace MauiCanvas;

public static class MauiProgram
{
	public static MauiApp CreateMauiApp()
	{
		var builder = MauiApp.CreateBuilder();
		builder
			.UseMauiApp<App>()
			.ConfigureFonts(fonts =>
			{
				fonts.AddFont("OpenSans-Regular.ttf", "OpenSansRegular");
				fonts.AddFont("OpenSans-Semibold.ttf", "OpenSansSemibold");
			});

#if __ANDROID__
        ImageHandler.Mapper.PrependToMapping(nameof(Microsoft.Maui.IImage.Source), (handler, view) => PrependToMappingImageSource(handler, view));
#endif

        return builder.Build();
	}

#if __ANDROID__
    public static void PrependToMappingImageSource(IImageHandler handler, Microsoft.Maui.IImage image)
    {
        handler.PlatformView?.Clear();
    }
#endif

}

@mohachouch
Man I keep my fingers crossed your workaround does it´s job. I will give it a try.... Thanks!

hided · 2022-12-01T09:32:17Z

I'm struggling to understand how an issue as prominent as this one, a hard crash on android when simply displaying an image and tabbing away and back, has been seemingly ignored for so long and even moved to the backlog (on another referenced similar issue).

Thanks a lot @mohachouch for your time investigating and seemingly finding a workaround. Will definitely try this one later today.

FM1973 · 2022-12-01T17:11:00Z

@mohachouch
So far no crash the whole day! Thanks a lot!
I can´t understand why the team was not able to provide a solution as quick as you.
I know there is a lot to fix in maui, but this one made android apps unusable.
Thanks again!

mohachouch · 2022-12-02T08:49:52Z

Your welcome @FM1973

I remind you that the workaround is not a correction, it's just for waiting a more permanent fix.

I noticed an strange thing, in my case I don't have to clear but just to declare the method is enough to fix the bug.

@FM1973 can you check that it works on your side ?

Not applying this workarround does not work for everyone

#if __ANDROID__
    public static void PrependToMappingImageSource(IImageHandler handler, Microsoft.Maui.IImage image)
    {
    }
#endif

According to the source code, assignment of item is done asynchronously, may be related to that :

@mohachouch
Yes, I know it´s only a workaround and it is marked as such in our source code.
I will check if only declaring the method is enough, I can´t before next week, but will get back to you when done.

@mohachouch
Not really. Still get the error without handler.PlatformView?.Clear(); With handler.PlatformView?.Clear(); all is OK.

@mohachouch @1357310795
Same here. Removing Clear is bringing back instability.

Thank you for the tests, I do not understand why on my test it works.

It's safer to clear anyway while waiting for Microsoft's fix.
