Can you add this to Grade an Maven? about untis4j

[bytedream]

Yes I can add gradle and maven support in the next update. I'm currently writing a discord bot based on this library an I never got an error (i've tested it with multiple accounts). Do you get this error while using the login method? If yes, you mabye using the wrong server url. When you are at the webuntis login screen the url is https://xyz.webuntis.com/WebUntis/?school=abc-school#/basic/main (for example). For the url parameter in the login method you have to extract the https and the server (or base url), in this case it is https://xyz.webuntis.com. For the school name you have to enter the text between ...?school= and #/basic... in this case abc-school. The final result for this example would be Session.login("username", "password", "https://xyz.webuntis.com", "abc-school"). If you've already tried this and still get the error you can comment the error here so I can analyze it

If I catch all exceptions and print them out I only get null

[bytedream]

What happens if you remove the try catch and run it again?

[xRealNeon]

Instant crash

[bytedream]

And error message / stack trace?

[xRealNeon]

Nothing

[bytedream]

Which example do you use?

[xRealNeon]

The first one without any action just the login

[bytedream]

The login itself doesnt give any response. Try to print out session.getKlassen()

[xRealNeon]

Im not on my pc right now ill do it and report back what it does

[bytedream]

Ok^^

[xRealNeon]

like i said when i do https:// and then the server url it crashes without any output

[bytedream]

Even when you try session.getKlassen()?

[xRealNeon]

yes

[bytedream]

Do you use the release 1.0 jar?

[xRealNeon]

the latest from the readme

[bytedream]

Hm ok. I could send the pre 1.1 release jar here. Maybe it will work then but currently im not on my pc, so you have to wait about 2.5 hours. Alternatively you can download the source code, unzip it and try to include it into your project if you not want to wait for my jar

[bytedream]

Here's the jar file (its zipped because github don't support jar file uploads in issues): untis4j-pre-1.1.zip

[xRealNeon]

doesn't work

[bytedream]

hmm. Could you paste your code here?

[xRealNeon]

 try {
            Session session = Session.login("", "", "https://borys.webuntis.com", "");  // create a new webuntis session

            System.out.println(session.getKlassen());

            session.logout();  //logout
        } catch (LoginException e) {  // this exception get thrown if something went wrong with Session.login
            System.out.println("Failed to login: " + e.getMessage());
            return;
        } catch (IOException e) {  // if an error appears this get thrown
            e.printStackTrace();
            return;
        }

[bytedream]

Well i copy pasted the code (and used my username, password, server and school name) and it works fine. Weird

[xRealNeon]

yeah

[xRealNeon]

Oh, I didn't mention I'm using this in an app

[bytedream]

Then it will probably be an android app. Does the android version you've chosen support java8?

[xRealNeon]

I use the SDK version 26

[bytedream]

Currently I have tested the api only with the "normal" Java. Android support is not bad at all, so I will test the api on android as well. If there is any progress / if i find the bug or whatever this is, i'll post it here^^

[bytedream]

I've used a empty activity and added: the api and the org.json library; android.permission.INTERNET to the android manifest file.
Then I added the following to the onCreate(...) method:

this.requestPermissions(new String[]{Manifest.permission.INTERNET}, 0);
Thread t = new Thread(() -> { //if i would do this without a thread a 'android.os.NetworkOnMainThreadException' gets thrown
        try {
             Thread.sleep(5000);
        } catch (InterruptedException e) 
              e.printStackTrace();
        }
        try {
              Session session = Session.login("username", "password", "https://xyz.webuntis.com", "a-school");

              System.out.println(session.getKlassen());
        } catch (IOException e) {
              e.printStackTrace();
        }
});
t.start();

And it worked (with virtual and real device)

Here is the app if you want to test it: MyApplication.zip

[bytedream]

Does it work now? I'll close this issue with the next version if you wont't answer

[xRealNeon]

I get this error when i use session.getKlassen() and without it it works kind of
java.lang.NoSuchMethodError: No static method metafactory(Ljava/lang/invoke/MethodHandles$Lookup;Ljava/lang/String;Ljava/lang/invoke/MethodType;Ljava/lang/invoke/MethodType;Ljava/lang/invoke/MethodHandle;Ljava/lang/invoke/MethodType;)Ljava/lang/invoke/CallSite; in class Ljava/lang/invoke/LambdaMetafactory; or its super classes (declaration of 'java.lang.invoke.LambdaMetafactory' appears in /apex/com.android.art/javalib/core-oj.jar)

[xRealNeon]

the only thing that works is session.getInfos()

[bytedream]

Have you tried to run the zipped app that i've sent?

[bytedream]

There is no Maven / Gradle support planned as I am not a big fan of it. And since I haven't received an answer for a long time, I think the Android problem is solved (or you use a different API).
