Crashes and ANRs on Android produce a stack trace, which is a snapshot of the
sequence of nested functions called in your game up to the moment it crashed.
These snapshots can help you identify and fix any problems in the source.

However, when you build your game with Unity in release mode, the symbols are
not packed with the APK. If your game crashes or has ANRs, the call stack only
shows the memory address.

For example:

Google Play supports uploading a debug symbols file for each version of your app
in Play Console. This makes it easier to analyze and fix your crashes and ANRs.

From Unity 2020.3 and higher, you can follow Unity's guidance to generate
[Android symbols](https://docs.unity3d.com/2020.3/Documentation/Manual/android-symbols.html)
and then [upload the symbolication file](https://support.google.com/googleplay/android-developer/answer/9848633#zippy=%2Cupload-files-using-play-console) to Google
Play Console to see a human-readable stack trace on the Android Vitals
dashboard.

Otherwise, you can follow the
[Symbolicate Android crash](https://support.unity.com/hc/en-us/articles/115000292166-Symbolicate-Android-crash) article from
Unity to manually resolve the stack trace or generate symbol files for lower
versions of Unity.
