The operation select list item cannot accept the arguments

Help me

when I press the back button it immediately appears and the display returns like the initial login to the application.

Do I have to tick only 1 block or other blocks such as login/register because between that block and the other blocks it is already connected to the database that I store on my computer using localhost.

because when I test the application on my computer with Connect to Companion via smartphone it runs smoothly and there are no errors like the one that appears above, but when I export the application and run it on the smartphone suddenly the problem appears as above.
sorry if my English is bad

Your list is an empty text, but not a list
Also to be able to select the second item, the list must have at least 2 items


  1. what is your android version?
  2. Where do you get the list?
