textView.setText(""+userAge);
this to this
textView.setText(userAge);
onclick method shutdown app on VM both code work same goal, but i don't understand why second row doesn't work
moxy :
You can't use setText with integer inside. You first need to convert it to a string.
There is two options, textView.setText(""+userAge);, textView.setText(String.valueOf(userAge));
