Displaying integer on toast

Toast.makeText either takes a CharSequence or an int as its second argument.

However, the int represents a resource ID (such as R.string.hello_world).

The application crashes probably because no resource is found with that ID, since it’s not an ID to start with, but an arbitrary integer.

In your case, use Toast.makeText(this,String.valueOf(bignum),Toast.LENGTH_LONG).show();.
