Hi,

Just updated to .NET 9 and Telerik MAUI 8.0.0.

Getting a crash when using a RadDataGrid on android 5.1.1 (this version is supported by .NET 9). The crash was not happening on .NET 8 and Telerik MAUI 7.0.0.

        <telerik:RadDataGrid x:Name="dataGrid" ItemsSource="{Binding Items}" AutoGenerateColumns="False">

            <telerik:RadDataGrid.Columns>
                <telerik:DataGridTextColumn PropertyName="Name" SizeMode="Auto"/>
                <telerik:DataGridTextColumn PropertyName="Value" SizeMode="Stretch"/>
            </telerik:RadDataGrid.Columns>
            <telerik:RadDataGrid.GroupDescriptors>
                <telerik:PropertyGroupDescriptor PropertyName="Section"/>
            </telerik:RadDataGrid.GroupDescriptors>
        </telerik:RadDataGrid>

It looks like Telerik.Maui.Handlers.RadTextInputHandler.MapCustomCursorColor is trying to call to a function that does not exist in android 5.1.1.

Hello Anthony,

I have logged the behavior here: https://feedback.telerik.com/maui/1671195-entry-unhandled-exception-on-android-5-1-with-telerik-maui-8-0-0 and escalated to the dev team. 

As a solution use higher version than 5.1. For example I tested on Android 11, 12, etc.

Regards,
Didi

Hi Didi,

Thanks, but your suggested solution is not applicable. We have customers with tablets running Android 5.1.1, we cannot ask them to spend money on new tablets because of a bug in software.

Hi anthony,

I understand your point. Still the Border and Entry controls we have in 8.0.0 version use API that is not available for 5.1 Android version.

You can add the following code in the App.xaml.cs file. Still these code removes the border control

public partial class App : Application
{
    public App()
    {

        InitializeComponent();
#if ANDROID
        Telerik.Maui.Handlers.RadTextInputHandler.TextInputMapper.ModifyMapping("CustomCursorColor", (h, v, m) => { });
        Telerik.Maui.Handlers.RadBorderHandler.BorderMapper.ModifyMapping(nameof(IRadBorder.Background), (h, v, m) => { });
        Telerik.Maui.Handlers.RadBorderHandler.BorderMapper.ModifyMapping(nameof(IRadBorder.BackgroundColor), (h, v, m) => { });
        Telerik.Maui.Handlers.RadBorderHandler.BorderMapper.ModifyMapping(nameof(IRadBorder.BorderColor), (h, v, m) => { });
        Telerik.Maui.Handlers.RadBorderHandler.BorderMapper.ModifyMapping(nameof(IRadBorder.BorderBrush), (h, v, m) => { });
        Telerik.Maui.Handlers.RadBorderHandler.BorderMapper.ModifyMapping(nameof(IRadBorder.CornerRadius), (h, v, m) => { });
        Telerik.Maui.Handlers.RadBorderHandler.BorderMapper.ModifyMapping(nameof(IRadBorder.BorderThickness), (h, v, m) => { });
#endif
        this.MainPage = new MainPage();
    }
}

Hi Didi,

I just ran our app on an Android 9 tablet and this crash is happening on Android 9 as well. I haven't tested your workaround as yet.

Hi Anthony,

We are aware the issue happens also on .NET 9. In the log bug report, we do not specify the .NET version.

Give the workaround a try, still keep in mind that this workaround removes the border. This is the option I can suggest.

Hi Didi,

The workaround stops the crashes, however all of the RadBorder elements I have used everywhere else in the app also get removed which isn't great.

Hi Anthony, 

I explained that the workaround removes the border. This is the option I can suggest for now, also you can downgrade the Telerik MAUI version to 7.1.0 as the behavior happens with 8.0.0 version.

Hi Didi,

I will be rolling back to 7.1.0 as most Telerik controls use the RadBorder for underlines and the app ends up looking terrible and inconsistent without them.

I hope Telerik fixes these crashes as a priority, many of your customers would still be using these older android versions. Those versions are officially still supported by MAUI so any MAUI related controls should also support them.

Regards

Anthony

I can assure you the case is escalated to the dev team.

FYI, I also have this issue, and Maui does say that the Android requirements have not changed. I will admit that, right now, this affects only my testing. However, when my app is released, this could easily be an issue. Thanks.

Hi all,
The issue is fixed in Telerik MAUI 10.0.0 version. Update to the latest version and test the fix on your side https://feedback.telerik.com/maui/1671195-entry-unhandled-exception-on-android-5-1-with-telerik-maui-8-0-0

I just have to say again that the serendipitous timing was nice... gotta take wins when they come! And, yes, the fix does indeed work!
