Include native symbols in your release build
Stay organized with collections Save and categorize content based on your preferences.

By default, native code libraries are stripped in release builds of your app. This stripping consists of removing the symbol table and debugging information contained in any native libraries used by your app. Stripping native code libraries results in significant size savings; however, it's impossible to diagnose crashes on the Google Play Console due to the missing information (such as class and function names). To debug crashes, you must include a debug symbols file with your app in Play Console.

Upload a symbols file

The Google Play Console reports native crashes under Android vitals. With a few steps, you can generate and upload a native debug symbols file for your app. This file enables symbolicated native crash stack traces (that include class and function names) in Android vitals to help you debug your app in production. These steps vary depending on the version of the Android Gradle plugin used in your project and whether you're using an Android App Bundle (recommended) or APK.

Android Gradle plugin version 4.1 or later

If your project builds an Android App Bundle (AAB), you can configure your build to automatically include the native debug symbols file in the AAB so it's uploaded to the Play Console when you publish your app. To include this file in release builds, add the following to your app's build.gradle.kts file:

android.buildTypes.release.ndk.debugSymbolLevel = { SYMBOL_TABLE | FULL }

Select the debug symbol level from the following:

Use SYMBOL_TABLE to get function names in the Play Console's symbolicated stack traces. This level supports tombstones.
Use FULL to get function names, files, and line numbers in the Play Console's symbolicated stack traces.

If your project builds an APK, use the android.buildTypes.release.ndk.debugSymbolLevel setting shown earlier to generate the native debug symbols file separately. Manually upload the native debug symbols file to the Google Play Console (the process is similar to uploading a mapping file to deobfuscate stack traces). As part of the build process, the Android Gradle plugin outputs this file in the following project location:

app/build/outputs/native-debug-symbols/<var>variant-name</var>/native-debug-symbols.zip

Android Gradle plugin version 4.0 or earlier (and other build systems)

As part of the build process, the Android Gradle plugin keeps a copy of the unstripped libraries in a project directory. This directory structure is similar to the following:

app/build/intermediates/cmake/universal/release/obj/
├── armeabi-v7a/
│   ├── libgameengine.so
│   ├── libothercode.so
│   └── libvideocodec.so
├── arm64-v8a/
│   ├── libgameengine.so
│   ├── libothercode.so
│   └── libvideocodec.so
├── x86/
│   ├── libgameengine.so
│   ├── libothercode.so
│   └── libvideocodec.so
└── x86_64/
    ├── libgameengine.so
    ├── libothercode.so
    └── libvideocodec.so

Zip up the contents of this directory:

cd app/build/intermediates/cmake/universal/release/obj
zip -r symbols.zip .

Manually upload the symbols.zip file to the Google Play Console.
