OsObject.notifyChangeListeners() get obfuscated by the proguard

[codguru]

I've got this error on LTE. No wifi. What's matter? I tested with proguard.

Realm sync feature enabled: no

Android Studio version: 2.3.1

Which Android version and device: Galaxy S7 7.0

[codguru]

Self answer.
I added to proguard. it's work with no error.

-keep class io.realm.internal.OsObject { *; }

but, it is correct solution?

[beeender]

Thanks for figuring this out! I would say it is a bug in our side, we will fix it in the next release.
Before the release, adding

-keep class io.realm.internal.OsObject { *; }

will be a temporary solution.

Thanks !

[beeender]

Fixed by #4467. will be released in v3.1.2.
