Using Android Logcat

The toolbar is on the top of the window. Most Android Logcat controls can be found here.

Auto Run

When Auto Run is toggled, Android Logcat window will be launched automatically if you do Build And Run in Build Settings window.

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
