I have noticed my Android app is showing a significant uptick in crashes. I have 49 java.lang.IllegalStateException crashes with my Android app. Here is the specific text from the Google Play console: ```auto java.lang.RuntimeException: at android.app.ActivityThread.performLaunchActivity (ActivityThread.java:3827) at android.app.ActivityThread.handleLaunchActivity (ActivityThread.java:4003) at android.app.servertransaction.LaunchActivityItem.execute (LaunchActivityItem.java:85) at android.app.servertransaction.TransactionExecutor.executeCallbacks (TransactionExecutor.java:135) at android.app.servertransaction.TransactionExecutor.execute (TransactionExecutor.java:95) at android.app.ActivityThread$H.handleMessage (ActivityThread.java:2317) at android.os.Handler.dispatchMessage (Handler.java:106) at android.os.Looper.loop (Looper.java:246) at android.app.ActivityThread.main (ActivityThread.java:8595) at java.lang.reflect.Method.invoke (Native Method) at com.android.internal.os.RuntimeInit$MethodAndArgsCaller.run (RuntimeInit.java:602) at com.android.internal.os.ZygoteInit.main (ZygoteInit.java:1130) Caused by: androidx.fragment.app.Fragment$InstantiationException: at androidx.fragment.app.Fragment.instantiate (Fragment.java:566) at androidx.fragment.app.FragmentContainer.instantiate (FragmentContainer.java:57) at androidx.fragment.app.FragmentManager$3.instantiate (FragmentManager.java:390) at androidx.fragment.app.FragmentStateManager.

(ScreenFragment.java:42) ``` I am not an expert in Android by any means, so I have no idea where to zero in on what is causing these crashes. Flipping through the crash data, it appears to crash in both Android 11 (SDK 30) and Android 9 (SDK 28). Has anyone experienced this before? If so, did you figure out what was causing the crashes? I haven’t had anyone reach out to me for support, so I don’t know how big of a concern it is, but seeing the crashes popping up makes me want to investigate it and figure out what is causing the problem. Edit: After more digging, it is also showing up with Android 7 (SDK 24) and Android 7.1 (SDK 25); albeit less frequently. I assume that’s because a majority of my users are using newer devices. ---

I loaded the APK into Android Studio and let it run for a while. I had no issues on two different emulated devices. I don’t know if this is something I need to be concerned with or not, but I only had a handful of crashes before I released my v4 which was with the new AAB requirement. I have had a total of 79 crashes in the past 60 days. I would not have known about them unless someone contacted me with issues, but I was checking in the Play console and noticed all of these crashes. ---
