Logs Flooded by Settings$SettingNotFoundException When Using SfCartesianChart - Android.Provider.Settings+SettingNotFoundException: animator_duration_scale

[rokmeglic71]

I’m seeing dozens of these errors every time my page renders:

Application error: Android.Provider.Settings+SettingNotFoundException: animator_duration_scale

  --- End of managed Android.Provider.Settings+SettingNotFoundException stack trace ---
android.provider.Settings$SettingNotFoundException: animator_duration_scale
	at android.provider.Settings.parseFloatSetting(Settings.java:4071)

They completely disappear if I comment out the <chart:SfCartesianChart> in my XAML, so it looks like the Syncfusion chart is triggering an internal call to Settings.Global.getFloat("animator_duration_scale", …).

Everything in the UI works as expected, but my logcat is cluttered. Can someone point me in the right direction to fix or suppress these warnings?

---

Steps to Reproduce

1. Install the Syncfusion.Maui.Toolkit NuGet package.
2. Add a <chart:SfCartesianChart> to a page’s XAML.
3. Deploy the app to an Android device (debug mode).
4. Navigate to the page and watch log for repeated SettingNotFoundException entries.

---

Expected vs. Actual Behavior

• Expected: No SettingNotFoundException for animator_duration_scale should appear in the logs.
• Actual: Every time RecyclerView (used internally by Syncfusion) binds its view holder, Android throws and logs this exception.

---

Environment

• .NET MAUI: 9.0.90 (latest stable)
• Syncfusion.Maui.Toolkit: 1.05 (latest stable)

---

What I’ve Tried

• Commenting out the <chart:SfCartesianChart> — errors vanish.
• Searching StackOverflow ([this thread](https://stackoverflow.com/questions/78594019/android-provider-settingssettingnotfoundexception)).
• Reviewing a Copilot AI share that suggests Syncfusion uses RecyclerView internally ([link](https://copilot.microsoft.com/shares/AGXSuSiU2ttHt4L17Cb7M)).

• Copilot AI: Syncfusion’s use of RecyclerView

Questions

1. Is there a known fix in Syncfusion or .NET MAUI to avoid querying the missing "animator_duration_scale" setting?
2. Can I catch or suppress this exception at the Android/MAUI boundary?
3. Should this be filed as a bug with Syncfusion?

Any guidance or workaround would be greatly appreciated. Thank you.

Hi @rokmeglic71 ,

We’ve tested the scenario on our side but couldn’t reproduce the animator_duration_scale exception. The app runs as expected with the current setup and package versions.

To help you further, we’ve included a sample and demo that shows how the controls are used. You can try running it on your device to see if the issue still occurs.

MAUITestApp.2.zip

ChartNavigationDemo.mp4

If the problem continues, please share more details like your device model, Android version, or emulator settings so we can assist you better.

Regards,
Fathima M

Thank you @SaiyathAliFathima for your time and effort.
Please add unhandled exception logging and you will see the errors.

Hi @rokmeglic71,

Thank you for your suggestions to log the exceptions in the output window.

In our specific case, the exception was related to chart rendering with animation. By default, Android enables animations. However, some users disable animations via Developer Options by adjusting the Animation scale settings to improve performance. If Developer Options have never been enabled on the device, these settings may not be accessible, which can lead to exceptions when attempting to apply animations.

To handle this scenario gracefully, we’ve wrapped the animation logic in a try-catch block.
maui-toolkit/maui/src/Core/Legend/AreaBase.cs at 925583090de21671eff50a35acdcb125636036a9 · syncfusion/maui-toolkit,
Based on whether an exception is thrown, we dynamically decide whether to render the chart with or without animation. This ensures a consistent and crash-free experience across different device configurations.

As you have triggered the FirstChanceException, this exception message was logged in the output window even if we handle the exception.

[rokmeglic71]

Could you change the code so it will not thrown an exception please?
CoPilot guided me to the way of using function with default value if the setting is not found. This way, the exception would not be thrown.

Hi @rokmeglic71 ,

Thank you for your input. I tried checking the details you provided, but unfortunately, the links are either inaccessible or not opening on my end.

Could you please share a screenshot of the relevant content and paste the exact details here directly?

[rokmeglic71]

Sorry, the last link does not work. Fixed. Link to documentation.

[rokmeglic71]

@SaiyathAliFathima any update on this? Thank you.

[SaiyathAliFathima]

Hi @rokmeglic71 ,
We would like to let you know that the requested changes have been merged - #255 . Thanks for raising it.

[rokmeglic71]

@SaiyathAliFathima great work, thank you.
