Hi, i am working on a xforms app that uses syncfusions SfAutoComplete control. On UWP the app works like a charm but on android the app hits a uncatched system exception whenever i try to use the SfAutoComplete box. The only part of the log in visual studio that makes any sense is "E/ArrayAdapter(21302): You must supply a resource ID for a TextView". What is this and how can i solve it?
Thanks in advance.
