Getting java.lang.NoSuchFieldException: ON_START for Android Arch Lifecycle

Question

I am having a library for SDK that extends both Application.ActivityLifecycleCallbacks, LifecycleObserver. In the constructor, I am registering the class as an observer for ProcessLifecycleOwner.

ProcessLifecycleOwner.get().getLifecycle().addObserver(this);

For the method that does ON_START work, I have added the following annotation for the same.

@OnLifecycleEvent(Lifecycle.Event.ON_START)

This works completely fine in a local and testing environment. Even for the release version, it works fine. But very rarely it fails with the following error:

   at android.arch.lifecycle.LifecycleRegistry$ObserverWithState.<init>(SourceFile:347)
   at android.arch.lifecycle.LifecycleRegistry.addObserver(SourceFile:162)

This error is very rare. I have only seen this happen for Android 5.0, 5.0.1 and 5.0.2 on device Samsung.

I am using android.arch.lifecycle:extensions:1.1.1.

Can someone please help me with this?

Which version of Lifecycle you are using ? add the dependency with question . — ADM, Feb 15 '19 at 06:31

Apparently there is some bug on Samsung devices for which reflection fails, very occasionally though.

I posted this on google issue tracker and got the below answer:

Solution is to migrate to Java 1.8 / Kotlin and use DefaultLifecycleObserver that internally does not use reflection.

Haven't tried this solution yet. Will post if it worked or not.
