error:(42, 29) error: no suitable constructor found user(int) constructor user.user(string,string) not applicable (actual , formal argument lists differ in length) constructor user.user(string,string,int,int,string,string) not applicable (actual , formal argument lists differ in length)

its said error:(41, 38) error: cannot find symbol variable pin how can find , make right.?

btn_pin = (button) findviewbyid(r.id.btn_pin); int pin = integer.parseint(input_pin.gettext().tostring()); input_pin = (edittext) findviewbyid(r.id.input_pin); 

you should use input_pin after findviewbyid, or nullpointerexception.
