Convert the number to string i.e
int num = 5;
String n = num + "";

and then,
num1.setText(n);

Solution 1

setText[^] with a single int parameter used to set the text from a resource where the int is the resource id...In your case it will look for the resource with id 4 - which does not exists...
Convert the number to string using .toString() method of the int type...

Hi,

The error means a resource you've used couldn't be found.

Please check that you've created a TextView with the id of textView14.

Lastly, change the line:

Java

num1.setText(a);

to:

Java

num1.setText(a.toString());

This is because TextViews only accept text in form of String.
