When I launch my app from Android Studio, with Facebook SDK installed on my device, Xiaomi Mi A2, it triggers the same error trhee times. It does not stop the app, but I don't know if I am missing something or simply, it is not important, but in the end, it is an error and I want to clarify it.

I am using Android Studio 3.4.1, Android 9 on the Xiaomi A2 and the new clause in build.gradle file is implementation 'com.facebook.android:facebook-android-sdk:5.1.0'. Error has not appeared before upgrading Facebook SDK.

This is what appears in Logcat:

EDIT The issue has been fixed in version 5.1.1.

Revert to 5.0.3 to get rid of this. 5.1.0 is actually crashing in production at this method (there's a bug report here). GitHub commits of this file show its rather flawed, the method is called from multiple threads concluding to a concurrency crash because it's using a static ArrayList.

Lately the core FB SDK is kinda bloated with useless stuff and low-quality code. The codeless stuff "feature" that simply can't even be turned off is especially a horror to look at. If you don't strictly need the FB SDK in your app, I'd avoid it until they get their shit figured out.
