Maybe it’s been a long day and I’ve overlooked something, but this is driving me absolutely crazy.
String address = "184.108.40.206".split("."); Log.d(TAG, "Address array length: "+address.length); //Output: 'Address array length: 0'
I am resolving the device IP address, and trying to split it into an
String array by splitting it on the period characters. Obviously this should return an array with a length of 4, but it’s returning a length of 0.
Is there something blatantly obvious I am overlooking here?
NOTE: The real code is pulling that IP address in from
WifiManager, but even if I put an arbitrary IP String in there like above, the length is 0.
The argument to
split is a regular expression, and the
. has a special meaning, so you’ll need to escape it:
String address = "220.127.116.11".split("\.");
