Sir I'm getting this
Case R.id.btn

Hello sir I'm having an error at the end saying constant expression expected 😢😢

im having with the case step...

instead of using switch you can use if-else conditions such as

@Override
public void onClick(View view) {
N1 = getIntFromEditText(editTextN1);
N2 = getIntFromEditText(editTextN2);
if(view.getId()== R.id.btn_addition){
textView.setText("Answer = " + (N1 + N2));
}
else if (view.getId()== R.id.btn_subtraction){
textView.setText("Answer = " + (N1 - N2));
}
else if (view.getId()== R.id.btn_multiplication){
textView.setText("Answer = " + (N1 * N2));
}
else if (view.getId()== R.id.btn_division){
textView.setText("Answer = " + ((float)N1 - (float)N2));
}

}
}

Instead of using switch case you can use if-else conditions like this:
if(view.getId()== R.id.btn_addition){
textView.setText("Answer = " + (N1 + N2));
}
else if (view.getId()== R.id.btn_subtraction){
textView.setText("Answer = " + (N1 - N2));
}
else if (view.getId()== R.id.btn_multiplication){
textView.setText("Answer = " + (N1 * N2));
}
else if (view.getId()== R.id.btn_division){
textView.setText("Answer = " + ((float)N1 - (float)N2));
}
