Looks like strange bug on samsung. One thing you can't do on your side is to move your app to java8/kotlin and use https://developer.android.com/reference/android/arch/lifecycle/DefaultLifecycleObserver (it is in common-java8 artifact) for all your observers, so you'll never fallback to reflection and never hit this bug

Sorry, one thing you CAN DO on your side is to move on java8/kotlin. Sorry for typo
Description
Version used: 1.1.1
Devices/Android versions reproduced on: Samsung devices with Android 5.0, 5.0.1 and 5.0.2 (Some of it)
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:
Caused by java.lang.NoSuchFieldException: ON_START

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?
