Hi Kirill, 
We have checked the reported issue and we afraid that we are unable to reproduce the issue. So, can you please share your device information, OS version, video of the issue or code snippet, application scenario with replication steps? This will be helpful for us to investigate further and provide you a better solution at the earliest.

This issue still exist. if you have an entry inside the listview and you edit the text and press enter or save on android, it throws this exception.

Hi Emil,

We would like to let you know that mentioned crash related to SfTextInputLayout has been fixed already. As per your mentioned issue reproducing cases, we have some concern on this, 
  • Could you please confirm whether this crash occurred when adding the Entry alone to the ListView or else Entry as InputView of SfTextInputLayout?

  • Could you please confirm same crash has been reproduced at our end?

  • Are you ensuring this with ListView or Syncfusion SfListView?
In the case of reported issue only with the framework element of Entry & ListView, please check with Xamarin team or else please share us with the issue replicating sample which will be more helpful to check at our end and provide a possible solution since we ensure, that is worked fine at our end.

Sridevi S.
