I\'m trying to develop an app that will take a number from the dial pad and call another number instead. But i get a number format exception on the phonenumber i want to call. <
2156689451 is too big for an int (which range from -2^31≈-2,147E9 to +2^31-1≈2,147E9, whereas your number is ~2,15E10)
2156689451
Use long instead of int...
long
int
