NumberFormatException

Question

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. <

Answer 1

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)

Use long instead of int...

Answer 2

That's because 6768886877 is too big of a number for an int.

Use a long instead.

long checkNumber = 0l;

try{
  checkNumber = Long.parseLong (phoneNumber);
}
catch (NumberFormatException e)
{
  e.printStackTrace();
}
