Is there a convenient way to create Parcelable data classes in Android with Kotlin?

Kotlin 1.1.4 is out

Android Extensions plugin now includes an automatic Parcelable implementation generator. Declare the serialized properties in a primary constructor and add a @Parcelize annotation, and writeToParcel()/createFromParcel() methods will be created automatically:

@Parcelize
class User(val firstName: String, val lastName: String) : Parcelable

So you need to enable them adding this to you module's build.gradle:

apply plugin: 'org.jetbrains.kotlin.android.extensions'

android {
    androidExtensions {
        experimental = true
    }
}

You can try this plugin:

android-parcelable-intellij-plugin-kotlin

It help you generate Android Parcelable boilerplate code for kotlin's data class. And it finally look like this:

data class Model(var test1: Int, var test2: Int): Parcelable {

    constructor(source: Parcel): this(source.readInt(), source.readInt())

    override fun describeContents(): Int {
        return 0
    }

    override fun writeToParcel(dest: Parcel?, flags: Int) {
        dest?.writeInt(this.test1)
        dest?.writeInt(this.test2)
    }

    companion object {
        @JvmField final val CREATOR: Parcelable.Creator<Model> = object : Parcelable.Creator<Model> {
            override fun createFromParcel(source: Parcel): Model{
                return Model(source)
            }

            override fun newArray(size: Int): Array<Model?> {
                return arrayOfNulls(size)
            }
        }
    }
}

Just click on the data keyword of your kotlin data class, then press alt+Enter, select the first option saying "Add Parceable Implementation"
