cordova-HTTP: most simple GET request not working

I'm trying to send a GET request from my Android emulator to the laptop on which the emulator is running, using the cordova plugin "cordova-HTTP":

cordovaHTTP.get(
            "http://10.0.2.2:80/",
            {},
            {},
            function(response) {
                console.log('success called');
            },
            function(error_response) {console.log('error called'); console.log(error_response.status);}
        );

The error callback gets called and the status code is 500 (= internal server error). But on my laptop I can see with tcpdump that no packages are even received. Why does this very simple GET request not work?

When I use Google Chrome on the emulator and navigate to "http://10.0.2.2:80/" everything works fine, I see the dummy page of the Apache2 webserver which is installed on my laptop.

Since API level 28 it is not allowed to send simple GET requests by default, because clear text traffic is not allowed. So I added the following to the config.xml of my cordova project (inside the <platform name="android"> tag):

<edit-config file="app/src/main/AndroidManifest.xml" mode="merge" target="/manifest/application"> 
<application android:usesCleartextTraffic="true" /> 
</edit-config>

Also make sure to add the android XML namespace inside your <widget> tag, otherwise the above won't work:
