Stacktrace Resolving

One benefit of using Android Logcat package is automatic stacktrace resolving. The addr2line tool in Android NDK is used to convert the addresses in the crash logs to the file names and line numbers. Below is an example of what's added to the log.

The original log from Android logcat

E CRASH   :      #01  pc 01c65330  /data/app/com.CrashComp.Crash-J2Z_L0XSsSAZPkt9lab2rQ==/lib/arm/libunity.so(DiagnosticsUtils_Bindings::ForceCrash(DiagnosticsUtils_Bindings::ForcedCrashCategory, ScriptingExceptionPtr*)+48)

The log shown in Android Logcat window in the Unity Editor

Error CRASH:    #01  pc 01c65330  /data/app/com.CrashComp.Crash-J2Z_L0XSsSAZPkt9lab2rQ==/lib/arm/libunity.so DiagnosticsUtils_Bindings::ForceCrash(DiagnosticsUtils_Bindings::ForcedCrashCategory, ScriptingExceptionPtr*) at ../Runtime/Export/Diagnostics/DiagnosticsUtils.bindings.cpp:25
