Decode Obfuscated Stack Trace

There are 2 ways to de-obfuscate stacktrace.

Method 1. Using Graphical User Interface​

  1. Proguardgui is a tool that will help deobfuscate stack traces.
    Proguardgui is located in path-to-sdk/tools/proguard/bin/.
  2. You need to open proguardgui.bat (for Windows users) or proguardgui.sh for (Mac or Linux users).
  3. Head over to the retrace section on the left side Proguard GUI tool.
  4. Set the path to your mapping file generated (automatically) during the release build that you have backed up from build/outputs/proguard/release/mapping.txt on your application module folder.
  5. Copy stacktrace from the Appxiom dashboard and paste it inside box titled obfuscated stack trace. Click on Retrace button.

Example snippet - Before DeObfuscation.​


example.app.android.be.u(Unknown Source)
example.app.android.we.b(Unknown Source)
android.app.Activity.performCreate(Activity.java:6975)
android.app.Instrumentation.callActivityOnCreate(Instrumentation.java:1213)
android.app.ActivityThread.performLaunchActivity(ActivityThread.java:2770)
android.app.ActivityThread.handleLaunchActivity(ActivityThread.java:2892)
android.app.ActivityThread.-wrap11(Unknown Source:0)

Example snippet - After DeObfuscation.​


com.example.app.android.MainActivity.getUserDetails(MainActivity.java:204)
com.example.app.android.MainActivity.onCreate(MainActivity.java:21)
android.app.Activity.performCreate(Activity.java:6975)
android.app.Instrumentation.callActivityOnCreate(Instrumentation.java:1213)
android.app.ActivityThread.performLaunchActivity(ActivityThread.java:2770)
android.app.ActivityThread.handleLaunchActivity(ActivityThread.java:2892)
android.app.ActivityThread.-wrap11(Unknown Source:0)

Method 2. Using Terminal​

  1. Copy the stacktrace from Appxiom dashboard to a file stacktrace.txt.
  2. Execute retrace.bat /path/to/mapping.txt /path/to/stacktrace.txt > deobfuscate.txt
  3. Use ./retrace.sh for Linux and Mac users.
  4. The de-obfuscated stacktrace will be written to the file deobfuscate.txt.
