Hi, I can't seem to pass my parcelable arrays to other activity, so is there anyone who can help me out/

[gildor]

Parcelable array? Array of parcelables?

[gildor]

Could you please show your code

[sqia09]

data class RoutesResponse(@SerializedName("result") val result: String,
@SerializedName("freason") val freason: String,
@SerializedName("route") var routesList: MutableList<RouteObject>,
@SerializedName("route_site") var routeSiteList: MutableList<RouteSite>) : Parcelable {

companion object {
@JvmField val CREATOR: Parcelable.Creator<RoutesResponse> = object : Parcelable.Creator<RoutesResponse>{
override fun createFromParcel(p0: Parcel): RoutesResponse = RoutesResponse(p0)
override fun newArray(p0: Int): Array<RoutesResponse?> = arrayOfNulls(p0)
}
}

constructor(source: Parcel) : this(source.readString(),
source.readString(),
source.createTypedArrayList(RouteObject.CREATOR),
source.createTypedArrayList(RouteSite.CREATOR))

override fun describeContents() = 0

override fun writeToParcel(p0: Parcel?, p1: Int) {
p0?.let {
with(it){
writeString(result)
writeString(freason)
writeTypedList(routesList)
writeTypedList(routeSiteList)
}
}
}
}

[sqia09]

the other two models of type RouteSite and RouteObject have similar parcelable implementation

[sqia09]

I'm sending the list like this:

[sqia09]

val testList = getRelevantRoutes(it.id)
toast (testList.size.toString())

startActivity(intentFor<GatewayActivity>(KEY_ROUTE_SITES to testList))

[sqia09]

and recieving using this:
val siteListFromIntent = intent.getParcelableArrayExtra("routesSiteList")[0]

[sqia09]

I'm geting source.readString can not be null when i try to read from intent.
I'll drop using anko if there's a work around

[gildor]

So what is error in your case?

[gildor]

Maybe source.readString is really null

[sqia09]

how can i fix it?

[sqia09]

java.lang.IllegalStateException: source.readString() must not be null

[gildor]

So string is null, it means that Parcel has no string in first position

[sqia09]

but the list is showing up in the activity from where I want to send my list

[gildor]

Try to debug your intent

[sqia09]

and also I'm getting it from the webservice

[sqia09]

ok

[sqia09]

how do you send intents to one kotlin activty to another and how do you read the?

[gildor]

Exactly the same way as in java

[gildor]

https://developer.android.com/guide/components/activities/parcelables-and-bundles.html

[sqia09]

in Kotlin? give me that line of code

[sqia09]

and do you implement Parcelable the way I've tried to do?

[gildor]

I do not implement Parcelable manually

[gildor]

Same way in kotlin, just copy paste

[sqia09]

have you used @Parcelize?

[gildor]

no

[gildor]

but it’s definitely nothing wrong to implement it manually

[gildor]

Are you sure that you need getParcelableArrayExtra?
val siteListFromIntent = intent.getParcelableArrayExtra(“routesSiteList”)[0]

[gildor]

because looks like you send list instead of array

[gildor]

there is getParcelableArrayListExtra
