Hi everyone. I'm pretty much a beginner. Right now I'm moving from intents to using NavigationController. My issue is that when I'm adding arguments, there is no argument for Double.

[Jean Paul Pacheco]

is using primitive wrappers an option when it comes to setting argument types in this case? I have not tried it personally but it might be an option.

[Jonny]

I'm not sure what that means

[Jonny]

Floot, Long, Boolean, String, Custom Parcelable, Custom Serializable

[Jonny]

Are my alternatives

[Jean Paul Pacheco]

I’m talking about something like

<argument
    android:name="argDouble"
    app:argType="java.lang.Double" />

[Jonny]

I'm trying it

[Jonny]

Got an error about class is java.lang.Double but found Float

[Jonny]

Caused by: org.xmlpull.v1.XmlPullParserException: Type is java.lang.Double but found float: 0
        at androidx.navigation.NavInflater.checkNavType(NavInflater.java:262)
        at androidx.navigation.NavInflater.inflateArgument(NavInflater.java:226)
        at androidx.navigation.NavInflater.inflateArgumentForDestination(NavInflater.java:146)

[Jonny]

is this the problem? android:defaultValue="0.0"

[Jean Paul Pacheco]

ok after looking a bit more into it, it seems that it’s just not possible to work with doubles as things are. Possibly once it’s out of the beta or a coming update might support it, but even using the primitive wrappers doesn’t seem like it will work. What you could do maybe is pass the value you need in a bundle when calling navigate()

[Jonny]

hm. that's so odd that they aren't supporting Double

[Jonny]

I need to pass google map location

[Jean Paul Pacheco]

I’m sure its in the works, as I see more than a few people have brought this up in forums. Fingers crossed at least 🤞

[Jonny]

Yes eventually 🙂.

[Jonny]

How would you modify this code to make it work?

[Jonny]

val action = SetLocationFragmentDirections.actionDestinationSetLocationToDestinationFindJobs()
                action.lat = job.lat
                action.lon = job.lon
                findNavController().navigate(action)

[Jonny]

It's hard learning android from scratch (almost). They keep the old functionality but you're not supposed to use it etc. A lot of talk when reading up on something is about how it's an improvement over the old technique that I don't yet know about.

[Jonny]

I'm using a string instead, and then convert it back

[Jonny]

I tried the bundle but the code gets messier and it doesn't use my action so it breaks my back stack
