I am new to android coding and need help with my project :



I have a function which I call from the OnResume of the mainActivity . The function reloads the data from the database and shows it on the list view .
Now when I go to second Activity and enter new data , the data is saved when onPause of secondActivity is called . On returning to mainActivity I don't see the changes made to list view but when I click on the same item of list view and go to second Activity again on returning for the 2nd time the changes start showing and the code works properly . What could be the possible reason for function not working in the 1st attempt ?



Note : I also call the function from onCreate of main Activity



Thanks in advance

Can I board the first leg of the flight without having final country's visa?

Image
5 Not asking because the hidden city ticketing. I have an upcoming flight from Shanghai -> Seattle -> Vancouver. However, I couldn't find my Canadian PR card. So in order for me to get back to Canada without applying for PRTD (permanent resident travel document) which takes a long time as well, I might need to rent a car from Seattle and drive back to Vancouver. So in this case, will the airline check my Canadian PR card? Or I can get away from just providing my US visa?
