Android: problems with getSelectedItem on a spinner

Question

I have a Spinner, and put the selected item in the body of a mail. this is my code:

@Override
protected void onCreate(Bundle savedInstanceState) {
         


        

Answer 1

It seems that Item is returned with NULL value try to Invoking the method from a null object.

TheNullPointerException is a RuntimeException and thus, the Javac compiler does not force you to use a try-catch block to handle it appropriately.

Hope this will help you to solve your issue.
