26,303 PointsIs it obligated to check a network present ?
I'm just curious about this. Is it suffice to check only connectivity ? Because if no connectivity , it means no network presents anyway.

9,447 PointsI did wonder this at first and do not 100% know the answer but my best guess is that we are first asking networkInfo whether or not it has the answers to questions we could ask it and then if it does have the answers we ask it if we are connected to the internet. However, if we asked networkInfo are we connected to the internet but networkInfo didn't have the answers then it would probably return with an error and maybe cause the app to crash. So basically if networkInfo has no information (networkInfo = null) for whatever reason, then it won't know whether there is a connection or not and can't return an answer. By using the code 'if (networkInfo != null && networkInfo.isConnected())' we are first checking whether networkInfo holds the answers, if not then we move on with our code (out of the 'if' statement) without asking the next question which would return an error. I hope that makes some sense.
