Is there another way to check this? I will poke around and see if anyone else has something.
What about something like this:
public static boolean isOnline() {
boolean connectivity;
try {
URL url = new URL("https://raw.github.com/DivineRPG/DivineRPG/master/Version.txt");
URLConnection conn = url.openConnection();
conn.connect();
connectivity = true;
} catch (Exception e) {
connectivity = false;
}
return connectivity;
}
This is not actually a Java bug, but rather an issue with the user's network configuration. If you are having this bug, and if you are on windows, open up your command prompt and please provide the output of "ipconfig /all"
If you only get this crash when not connected to the internet then it could be that I simply forgot to catch the exception, as it should only throw a null pointer if no internet connections could be found.
@krwminer That would "work" for just version checking, though still best to avoid that approach. You are not checking for an internet connection, you are attempting to make a connection, which will be slower and harmful to performance, especially if the connection would fail, as it will try to connect for quite some time before it fails. Also if for some reason github servers go down or the url changes, then even if connected you will be returning false. If you must do it this way, then check for a connection with a more common domain such as google.com. Furthermore, I had written the online check to be generic so that it could be used for more than just version checking, and even then like I said, if we were to not check for internet connection and simply try to make a connection to the version file, it would take a considerable longer amount of time than checking for an internet connection and then making a connection, of course depending on the user's machine and network configuration.
All that said, making a connection like that would be the next advisable option, as a TCP connection check, though still preferred, is a bit pointless for a simple check like this.
If people only get this crash when not connected to the internet, then this can be easily fixed. If they are connected to the internet and the output of "ipconfig /all" does not shed some light on the issue then the best course of action would be to do the URLConnection method in the catch block when a null pointer from the current method is caught
This happened when connected to the internet. I am trying to get the "ipconfig /all" for you.
@krwminer You can do "ipconfig /all > Desktop/ipconfig.txt" to make it go to a txt file in case thats why you are "trying" :)
Also what version of Windows are you on? And any security/anti virus programs running? These could also be factors
I am relaying the info from someone else, that is why I do not have it for you. If it was just me, you would have all the info you need by now. ;)
If they do not respond soon, I will try and replicate it.
You see this problem also, right? Do you think you could provide the information @BossLetsPlays is requesting? I would like to wrap this up and close this issue out as soon as possible.
Going ahead and closing this as commit 665 solves the crashing, though the ipconfig /all output will still be appreciated
