Butterknife: java.lang.IllegalStateException: at butterknife.internal.Utils.findRequiredView (Utils.java:92)

[CRoed]

I have an app using butterknife 8.8.1. A large amount of errors are showing up on my Play Console with the trace:
Caused by: java.lang.IllegalStateException: at butterknife.internal.Utils.findRequiredView (Utils.java:92) at butterknife.internal.Utils.findRequiredViewAsType (Utils.java:104) at com.xxxxxx.ui.activities.ChatActivity_ViewBinding.<init> (ChatActivity_ViewBinding.java:45) at java.lang.reflect.Constructor.newInstance0 (Native Method) at java.lang.reflect.Constructor.newInstance (Constructor.java:430) at butterknife.ButterKnife.createBinding (ButterKnife.java:199) at butterknife.ButterKnife.bind (ButterKnife.java:124) at com.xxxxxx.ui.activities.ChatActivity.onCreate (ChatActivity.java:218) at android.app.Activity.performCreate (Activity.java:6955) at android.app.Instrumentation.callActivityOnCreate (Instrumentation.java:1126) at android.app.ActivityThread.performLaunchActivity (ActivityThread.java:2927)

Every single device listed in my crash reports are Samsung phones/tablets running Android 7.0 or 7.1. I don't any physical device like that to test with, and I've been unable to replicate this error on any of the hardware I have.

Looking at that source file, I should be getting some more information about the illegal state exception by the traces that google is providing don't include the Log message. I can infer that the view it was trying to find was null. Do you have any debugging suggestions for this?

I don't really have any tips. The original exception for which that one is the cause has the information required. If you use a third-party crash reporting tool you will receive the entire trace.

Thanks, Jake. So I'm fairly new to Android and I see there's a ton of options available for third party crash reporting. If you have a recommendation I'd love to hear it.

Bugsnag is my favorite: bugsnag.com

Google probably pushes Crashlytics which is part of Fabric which is
semi-first-party.

You are receiving this because you modified the open/close state.

I'm getting this issue on my app. I can't just make the view @Nullable either, as it is a required field. i have the ids in my R file, and my compilers are all correct.
This issue only affects android tablets. I have tested and phones work without problem

[CRoed]

I apologize I never posted my fix here...

I had a landscape and portrait layout file. I was disregarding the portrait file and always loading landscape mode, however a few versions of android decided to load the portrait first and THEN load the landscape, and I had one typo with the wrong ID in the portrait layout. Bugsnag worked really well to help me find this (Thanks for the tip Jake Wharton).

I hope that helps you solve your issue.
