How can i use switch(mouseButton) in android mode?

Hi, this is the part of my code that works on java mode, but obviously it doesn't work in android mode, so my question is, can i use this kind of switch on my android project? How can i make this work? I tried to change the mouse button with mouse pressed but i understood that i cannot use a boolean in a switch. This is the error that occurs every time (5 equals errors):

1. ERROR in /private/var/folders/7h/__943dks5895p0qs_txz9p700000gn/T/android1454252317288703044sketch/src/processing/test/catchme/CatchMe.java (at line 101) switch(mouseButton) { ^^^^^^^^^^^

mouseButton cannot be resolved to a variable

This is the part of code of the first error:

void draw(){ // state if(mousePressed){ if(state == stateMenu){ if (rectOver) { switch(mouseButton) { case LEFT: state = statePlay; break; case RIGHT: state =stateLost; break; case ESC: // quit exit(); break; default: // do nothing break; } } }

}
