:-1: warning: Warning: QML import could not be resolved in any of the import paths: X

[Creaperdown]

I am trying to run my application on Android, but it crashes on startup, while running:

const QUrl url("qrc:/main.qml");
    QObject::connect(
        &engine, &QQmlApplicationEngine::objectCreated, &app,
        [url](QObject* obj, const QUrl& objUrl)
        {
            if(obj == nullptr && url == objUrl)
                QCoreApplication::exit(-1);
        },
        Qt::QueuedConnection);
    engine.load(url);

I get warnings saying that:

Thus I suspect that the cause of the crash is the engine not being able to find my import paths. I have found multiple mentions of it on the internet, but none of them had a solution.

I register my custom types via e.g.:

qmlRegisterSingletonInstance("Librum.controllers", 1, 0, "DictionaryController", dictionaryController);```
in my main.cpp file.

Does someone have an idea what might cause this?

@Creaperdown start small, have a minimal QML file. If it works, add more stuff until it crashes.

Bisecting like this gets you more information about why it crashes.
