Question

does anyone have any luck setting up the ` Parcelize` annotation on a class <https android jlelse eu yet another awesome kotlin feature parcelize 5439718ba220> i tried this but it doesnt recognize the import ```import kotlinx android parcel Parcelize``` and i did a gradle sync after adding ```android androidExtensions experimental = true ```

Anastasia Finogenova · Answer

I mean launching the app I had this lint issue where it was highlighted and then run as expected

```sealed class DifficultyLevel val columnCount Int val rowCount Int val flagsCount Int val minesCount Int Parcelable class Easy DifficultyLevel 10 10 10 10 constructor parcel Parcel this override fun writeToParcel parcel Parcel flags Int super writeToParcel parcel flags override fun describeContents Int return 0 companion object CREATOR Parcelable Creator lt Easy gt override fun createFromParcel parcel Parcel Easy return Easy parcel override fun newArray size Int Array lt Easy gt return arrayOfNulls size class Medium DifficultyLevel 13 13 23 23 constructor parcel Parcel this override fun writeToParcel parcel Parcel flags Int super writeToParcel parcel flags override fun describeContents Int return 0 companion object CREATOR Parcelable Creator lt Medium gt override fun createFromParcel parcel Parcel Medium return Medium parcel override fun newArray size Int Array lt Medium gt return arrayOfNulls size class Hard DifficultyLevel 16 16 69 69 constructor parcel Parcel this override fun writeToParcel parcel Parcel flags Int super writeToParcel parcel flags override fun describeContents Int return 0 companion object CREATOR Parcelable Creator lt Hard gt override fun createFromParcel parcel Parcel Hard return Hard parcel override fun newArray size Int Array lt Hard gt return arrayOfNulls size override fun writeToParcel parcel Parcel flags Int parcel writeInt columnCount parcel writeInt rowCount parcel writeInt flagsCount parcel writeInt minesCount ```

lawlorslaw · Answer

yes i just tried running the app

lawlorslaw · Answer

i ve add this to the top of my app `build gradle` file ```apply plugin kotlin android extensions ```

lawlorslaw · Answer

and i added this ```androidExtensions experimental = true ```

lawlorslaw · Answer

see it cannot resolve this annotation

lawlorslaw · Answer

there must be something else you need to set up to make this work

Anastasia Finogenova · Answer

Did you add both of these apply plugin kotlin android extensions apply plugin kotlin android

lawlorslaw · Answer

yes i did

lawlorslaw · Answer

i invalidated cache and restarted android studio but no luck with that either

lawlorslaw · Answer

looks like someone had a similar issue here <https youtrack jetbrains com issue KT 22213>

lawlorslaw · Answer

so i figured it out this is the correct order for the plugins ```apply plugin kotlin android apply plugin kotlin android extensions ``` i had it in reverse which is why it wasnt working

Anastasia Finogenova · Answer

Actually they are in reverse on the official docs how to include kotlin into existing Android project

lawlorslaw · Answer

thats a bummer that the docs have it all wrong i hope they update that
