Android app crashes when the user pinches the chart

[David Conlisk]

Hi all,

When a user pinches the graph on my app the app crashes with the following error message:

Java.Lang.ArrayIndexOutOfBoundsExceptionlength=1; index=1

Hi David Conlisk,

 

Thanks for contacting Syncfusion Support

 

We are not able to reproduce the issue at our end and we have prepared a sample with your code.  Please  update us the modified  sample for further assistance on this.

Thanks,

Hi Yuvaraj,

Thanks for the sample, which does work. I compared it with my version and realised the problem is to do with the fact that I'm using a MasterDetailPage in my app. I've updated your simple droid project to place the graph within a MasterDetailPage and it crashes when you pinch. Please see the attached updated project.

Thanks,

David

I faced the same issue.

Please share information if you have solution for this.

Thank you,

Hi Yuvaraj Palanisamy,

In my case, the problem raises only when I enable tooltip of series or chart.

When I remove tooltip, every thing is ok.

Please check it and fingure out.

I hope I can use tooltip in this case too.

Please let me know when you have solution.

Thank you
