Bug - RadRadialGauge is not visible in Release on an Android device

[Remmo]

Hi all,

I use a very simple RadRadialGauge, when I run in debug my app everything is ok, but when I start it in release mode, I cannot see anything on  real device, heres the code:
<telerikGauges:RadRadialGauge StartAngle="90" Margin="0" SweepAngle="360" HorizontalOptions="FillAndExpand" Padding="0" VerticalOptions="FillAndExpand" >
                                <telerikGauges:RadRadialGauge.Axis>
                                    <telerikGauges:GaugeLinearAxis Maximum="1"   
                                                       Minimum="0"
                                                       ShowLabels="False"
                                                       StrokeThickness="0" />
                                </telerikGauges:RadRadialGauge.Axis>
                                <telerikGauges:RadRadialGauge.Ranges>
                                    <telerikGauges:GaugeRangesDefinition Offset="0">
                                        <telerikGauges:GaugeRange Color="{StaticResource YukoLightBlue}"
                                                      From="0"                                                               
                                                      To="1" />
                                    </telerikGauges:GaugeRangesDefinition>
                                </telerikGauges:RadRadialGauge.Ranges>
                                <telerikGauges:RadRadialGauge.Indicators>                                    
                                    <telerikGauges:GaugeRangeBarIndicator Fill="{StaticResource YukoForceDarkBlue}"
                                                              FromCap="ConcaveOval"
                                                              ToCap="Oval"
                                                              Offset="0"
                                                              From="0"                                                             
                                                              To="0.45" />
                                </telerikGauges:RadRadialGauge.Indicators>
                            </telerikGauges:RadRadialGauge>

Any helps is appreciated.

 

Thanks

Hello Remmo,

I am pasting here the reply from the support ticket regarding the same topic:

When you switch to Release mode, this enables the linker. The linker will remove assemblies that have no references in the app code, if you don't have Xaml Compilation enabled, the XAML is not compiled and there are no references at compile time.

To ensure there are references to controls so that the linker doesn't remove unused assemblies, either give everything an x:Name or enable Xamarin XAML Compilation (aka XamlC). I recommend enabling it on the assembly level, instead of per-page, as seen in the first example.

And finally what resolved the issue: the supported architecture in release mode should be set to "armeabi-v7a".
