I am trying to get all the courses from user device, and show them on screen

I am trying to achieve the functionality of getting the courses from the Garmin devices and whenever any course is clicked the navigation should start with a corresponding course

until now what I've done is, that the application always crashes, and menu item did not get inflated any help will be highly appreciated,

try {
var iterator = PersistedContent.getCourses;
for (var i = 0; i < iterator.size(); i++) {
var content = iterator.next(); // Get the next object in the iterator
menu.addItem(
new MenuItem(
content.getName(),
"",
content.getId(), {}
)
);
}
} catch (exception) {
System.println("catch: " + exception);
} finally {
System.println("finally");
}

I don't think you can use an iterator like that (there's no size() method afaik)

Try something like this:

var iterator = PersistedContent.getCourses();
while (true) {
    var content = iterator.next(); // Get the next object in the iterator
    if (content == null) {
        break;
    }
    menu.addItem(
        new MenuItem(
            content.getName(),
            "",
            content.getId(),
            {}
        )
    );
}

is there any way I can get the courses from the Garmin account directly using an API call?

because I've tried a lot but there is an API that has a parameter of id which I don't have. is there any online sample for that Sir?
