call stack too long android application crashes

I am building a application for my father’s business. That can get data from google sheets in json format. then I am parsing the Json Data and storing them as array this works well in the editor and show the result in a combobox but as soon the the page loads there by firing the event construct that gets the data from google sheets and stores in array the app crashes and give the below error. I have around 315 elements of names and corresponding amount that the names owe my organisation
LogAndroid: Error: Crtical error:
LogAndroid: Error: Assertion failed: Result+ NumToAdd<=MaxElements
LogAndroid: Error: Maximum number of Uobjects exceeded
LogAndroid: Error: << callstack too long >>
