Crash when trying to leave a fragment that contains a Parceler unwrapped object

Question

I have an abstract class that is annotated with @Parcel. It has a concrete subclass MyMovie but it is not annotated.

I can successfully create a fragment by passing MyMovie to the args bundle. All is fine, for both wrapping MyMovie and unwrapping the parcelable.

Problem occurs when I try to leave the fragment, for example, by pressing home button. Here is the stack trace:

This is how I include Parceler in my app-level build.gradle:

compile 'org.parceler:parceler-api:1.1.1'

Thanks for helping.

I did the following to solve the problem: 1) make abstract class concrete 2) annotate the concrete class, and 3) apply the apt plugin. — Jonas, Sep 14 '15 at 13:34

I'd guess that you need to include the Parceler annotation processor in your Gradle script:

apt 'org.parceler:parceler:1.1.5'
