Document Realm compatibility with Parceler

Hi

I have a Realm object that is also Parcelable. I use Parceler as a workaround because it’s not possible to implement Parcelable on Realm objects. Everything has been working nicely so far, but I ran into a problem when I tried to launch an activity with ACTION_SEND set on the intent.

This is the Parceler exception I’m getting (logged a bug for them here https://github.com/johncarl81/parceler/issues/106):

org.parceler.ParcelerRuntimeException: Unable to find generated Parcelable class for io.realm.MessageRealmProxy, verify that your class is configured properly and that the Parcelable class io.realm.MessageRealmProxy$$Parcelable is generated by Parceler.

The realm object is called Message and is set to be parcelable using the following annotation:

@RealmClass
@Parcel(implementations = { Message.class }, value = Parcel.Serialization.BEAN, analyze = { Message.class })
public class Message extends RealmObject {

The class is not just a simple POJO, it has some static methods that parses data and some of the member variables are set as @Ignore, but I’ve tried simplifying it, and I still get the same error.

Haha I came across this now randomly almost 2 years later, after wanting to do the same thing again in a new project and realized I was the one who originally started this discussion. Glad to have helped. And to have helped myself. 😃

@johncarl81 Thanks for the answer. I found them under the build folder(using Find File tool in Android Studio), but can’t import. And if I don’t import them, I get a compile error if I try something like “implementations = { MyObjectRealmProxy.class }”.
