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();
.
