Unable to find generated Parcelable class for Room database.

[mmlaif]

This library start to crash my app on some users devices, I can't replicate the error to solve it or understand it!

Firebase shows:

Fatal Exception: org.a.d
Unable to find generated Parcelable class for com.mzdhr.taskboxes.database.b.a, verify that your class is configured properly and that the Parcelable class com.mzdhr.taskboxes.database.b.a$$Parcelable is generated by Parceler.

Do you have some example code where the issue is happening?

[mmlaif]

Code:

                /** Passing Data to More Info Dialog via a Bundle Args **/
                // Passing data to DetailsFragment via a Bundle
                android.app.FragmentManager manager = ((Activity) mContext).getFragmentManager();
                Bundle args = new Bundle();
                Parcelable wrappedTaskEntity = Parcels.wrap(taskEntity);
                args.putParcelable(Constant.TASK_PARCELABLE_KEY, wrappedTaskEntity);
                mMoreInfoDialog.setArguments(args);
                mMoreInfoDialog.show(manager, "TaskMoreInfoFragment");

This happen (inside a adapter/viewholder classes) when I try to Parcels lib to wrap my objects to send them as args to a dialog. It works fine, but in some phones the library can parcel my objects and app crash.

com.mzdhr.taskboxes.database.b.a

b.a is the entitiy/TAskEntitiy.java class that used with Room database. I think using proguard shriks resources names.

[johncarl81]

Are you splitting your app up into multiple different aars?

[mmlaif]

multiple different aars? activities, fragments, dialgos if you mean that then yes.

[johncarl81]

No, I mean android archives... We've seen issues with using Parcelables and classloaders between libraries. Doesn't sound like this is the case for you, however.

What version of Parceler are you using?

[mmlaif]

Oh. It was version 1.1.11. I upgrade to 1.1.12 trying to replicated the error but couldn't. I think i need other phone devices to do it.
