Is it possible to send arguments other than string or integer in android's new navigation component

Issue

The new navigation component is great! however I would like to send "Long" variables between my fragments.

writing this in the navigation graph file works:

<argument
        android:name="discussionId"
        app:type="string" />

writing this won't compile:

<argument
        android:name="discussionId"
        app:type="long" />

Currently, it seems I'm forced to parse them to and from string formats. It works fine, but it seems bizarre to me that I can't use primitive types such as long or byte or short for such a fundamental architecture. Am I missing something? Is this kind of feature set to be developed in the future?

Solution

At the moment you can't use safe args with types apart from integer, string, inferred and reference. An issue has been opened asking for other types.

But you pass a bundle programmatically when using the navigate() method to navigate to a destination:

var bundle = bundleOf("key" to amount)
view.findNavController().navigate(R.id.action_id, bundle)

And you can use the usual getArguments to retrieve the data in the destination fragment:

val value = arguments.getString("key")
