iOS+ (Apple platforms)
For Apple platform apps using the Crashlytics Unity SDK 8.2.0+, the Firebase
Unity Editor plugin automatically configures your Xcode project to upload
symbols. Download the latest version.
Android
For Android apps, the Crashlytics Unity SDK 8.6.1+ automatically includes
NDK crash reporting, which allows Crashlytics to automatically report Unity
IL2CPP
crashes on Android. However, to see symbolicated stack traces for native library
crashes in the Crashlytics dashboard, you must upload symbol information at
build time using the Firebase CLI.
(only for apps using Android API level 30+) Update your app’s
AndroidManifest.xml template to disable Pointer Tagging:
Check the box for Android Player Settings > Publishing Settings >
Build > Custom Main Manifest.
Open the manifest template located at
Assets/Plugins/Android/AndroidManifest.xml.
(only for apps using an SDK version before
8.8.0) Add the
following attribute to the application tag:
<application android:allowNativeHeapPointerTagging="false" ... />
Build your project and upload symbols.
Complete these steps each time that you create a release build or any build
for which you want to see symbolicated stack traces in the
Firebase console.
From the Build Settings dialog, do one of the following:
Export to an Android Studio project to build your project; or
Build your APK directly from the Unity Editor.
Before building, make sure the checkbox for Create symbols.zip is
checked in the Build Settings dialog.
Once your build has finished, generate a Crashlytics-compatible symbol
file and upload it to Firebase servers by running the following
Firebase CLI command:
FIREBASE_APP_ID: Your Firebase Android App ID (not your
package name)
Example Firebase Android App ID: 1:567383003300:android:17104a2ced0c9b9b
Need to find your Firebase App ID?
Here are two ways to find your Firebase App ID:
In your google-services.json file, your App ID is the
mobilesdk_app_id value; or
In the Firebase console, go to your
Project settings.
Scroll down to the Your apps card, then click on the desired Firebase
App to find its App ID.
PATH/TO/SYMBOLS: The path to the symbol file generated by the
CLI
Exported to an Android Studio project —
PATH/TO/SYMBOLS is the unityLibrary/symbols directory,
which is created in the exported project root after you build the app
via Gradle or Android Studio.
Built the APK directly from within Unity —
PATH/TO/SYMBOLS is the path of the zipped symbol file
generated in the project root directory when your build finished
(for example:
myproject/myapp-1.0-v100.symbols.zip).

Firebase CLI command for symbol file generation and upload
Flag
Description
--generator=csym
Uses the legacy cSYM symbol file generator instead of the
default Breakpad generator
Not recommended for use. We recommend using the default
Breakpad symbol file generator.
--generator=breakpad
Uses the Breakpad symbol file generator
Note that the default for symbol file generation is Breakpad.
Only use this flag if you've added
symbolGenerator { csym() }
in your build configuration and you want to override it to use
Breakpad instead.
--dry-run
Generates the symbol files but does not upload them
This flag is useful if you want to inspect the content of the
files that are sent.

You\nusually configure this behavior during the initial setup of Crashlytics in\nyour app, specifically by\n[adding a run script](/docs/crashlytics/get-started?platform=ios#set-up-dsym-uploading)\nthat automatically uploads dSYM files during your app's build phase.\n\nUnfortunately, there are a few cases that could cause your automatic dSYM files\nupload to fail. This guide provides some ways to troubleshoot when\nCrashlytics can't locate your app's dSYM files.\n\nMake sure Xcode can automatically process dSYMs and upload the files\n\nWhen setting up Crashlytics in your app, you\n[configured a run script](/docs/crashlytics/get-started?platform=ios#set-up-dsym-uploading)\nto automatically process dSYMs and upload the files.\n\nMake sure that your configuration for the Crashlytics run script is\nup-to-date with the new requirements which started with Xcode 15. If your\nconfiguration isn't up-to-date, you might be getting the following error: \n\n`error: Info.plist Error Unable to process Info.plist at path ...`.\n\nSpecifically, Xcode 15 and later requires that you provide a more complete set\nof file locations. For your Crashlytics run script\n(`firebase-ios-sdk/Crashlytics/run`), make sure that you have the following\nsetup:\n\n1. Click the **Build Phases** tab, and then expand the *Run Script* section.\n\n2. In the *Input Files* section, make sure you have the paths for the locations\n of the following files:\n\n ```\n ${DWARF_DSYM_FOLDER_PATH}/${DWARF_DSYM_FILE_NAME}\n ``` \n\n ```\n ${DWARF_DSYM_FOLDER_PATH}/${DWARF_DSYM_FILE_NAME}/Contents/Resources/DWARF/${PRODUCT_NAME}\n ``` \n\n ```\n ${DWARF_DSYM_FOLDER_PATH}/${DWARF_DSYM_FILE_NAME}/Contents/Info.plist\n ``` \n\n ```\n $(TARGET_BUILD_DIR)/$(UNLOCALIZED_RESOURCES_FOLDER_PATH)/GoogleService-Info.plist\n ``` \n\n ```\n $(TARGET_BUILD_DIR)/$(EXECUTABLE_PATH)\n ```\n If you have `ENABLE_USER_SCRIPT_SANDBOXING=YES` and `ENABLE_DEBUG_DYLIB=YES` in your project build settings, then include the following: \n\n ```\n ${DWARF_DSYM_FOLDER_PATH}/${DWARF_DSYM_FILE_NAME}/Contents/Resources/DWARF/${PRODUCT_NAME}.debug.dylib\n ```\n **Understand why the locations of these files are\n needed**\n\n Xcode looks in the specified locations for these input files to ensure\n that the build files are available for the run script. Also, if\n *User Script Sandboxing* is enabled, Xcode only allows the run\n script to access files specified in the *Input Files*.\n - Providing the location of your project's dSYM files enables Crashlytics to process dSYMs.\n - Providing the location of your app's built `GoogleService-Info.plist` file enables Crashlytics to associate the dSYMs with your Firebase app.\n - Providing the location of your app's executable allows the run script to prevent duplicate uploads of the same dSYM. Note that app binaries are *not uploaded*.\n\nCheck if Xcode is producing dSYMs\n\nMore often than not, dSYM files go missing because Xcode simply isn't producing\nthem. When an upload fails, Crashlytics displays a \"Missing dSYM\" alert in\nthe Firebase console. If you get this alert, first check that Xcode is\nproducing the correct dSYM for every build:\n\n1. Open your project in Xcode, and then select the project file in the Xcode\n Navigator.\n\n2. Select your main build target.\n\n3. Open the target's **Build Settings** tab, and then click **All**.\n\n4. Search for `debug information format`.\n\n5. Set **Debug Information Format** to **DWARF with dSYM File** for all\n your build types.\n\n6. Rebuild your app.\n\nYour crash reports should now appear in the\n[Crashlytics dashboard](https://console.firebase.google.com/project/_/crashlytics). If the problem persists or you\nencounter other errors, try [locating your dSYMs](#locate) and\n[uploading them to Crashlytics manually](#upload-dsyms).\n\nLocate your dSYMs on a local machine\n\nRun the following command to display all your dSYMs' UUIDs on your machine and\nsearch for the missing dSYM: \n\n```text\nmdfind -name .dSYM | while read -r line; do dwarfdump -u \"$line\"; done\n```\n\nOnce you find the dSYM, [manually upload it to Crashlytics](#upload-dsyms).\nIf the `mdfind` command doesn't return any results, you can look in the\n`Products` directory where your `.app` lives (by default, the `Products`\ndirectory is located in `Derived Data`). If your app is released to production,\nyou can also look for its dSYM in the `.xcarchive` directory on disk:\n\n1. In Xcode, open the **Organizer** window, and then select your app from the\n list. Xcode displays a list of archives for your project.\n\n2. Control-click an archive to view it in Finder. Control-click it again, and\n then click **Show Package Contents**.\n\n3. Within `.xcarchive` is a dSYMs directory that contains dSYMs generated as\n part of Xcode's archiving process.\n\nUpload your dSYMs\n\nCrashlytics supports multiple ways to upload your dSYMs files, either\n[automatically](#auto-upload-dsyms) or [manually](#manually-upload-dsyms).\n\n*(Recommended)* Automatically process your dSYMs and upload the files\n\nWhen you initially set up Crashlytics, you most likely configured this\nautomatic upload behavior for your app. However, if automatic uploads are\nfailing, [check that your configuration is correct](#check-input-files-setup).\n\nManually upload your dSYM files\n\nIf automatic uploads are failing, you can manually upload your dSYM files using\neither of the following options.\n\n- **Option 1** : Use the console-based \"Drag and Drop\" option to upload a zip\n file containing your dSYM files (go to the\n Firebase console \\\u003e\n [Crashlytics](https://console.firebase.google.com/project/_/crashlytics) \\\u003e\n *dSYMs* tab).\n\n- **Option 2** : Use the `upload-symbols` script that you can call from\n anywhere in your build process to manually upload your dSYM files. To run the\n `upload-symbols` script, use either of the following options:\n\n - **Option A**: Include the following line in your build process:\n\n ```gdscript\n find dSYM_DIRECTORY -name \"*.dSYM\" | xargs -I \\{\\} $PODS_ROOT/FirebaseCrashlytics/upload-symbols -gsp /PATH/TO/GoogleService-Info.plist -p PLATFORM \\{\\}\n ```\n - **Option B**: Run the script directly from your terminal:\n\n ```\n /PATH/TO/PODS/DIRECTORY/FirebaseCrashlytics/upload-symbols -gsp /PATH/TO/GoogleService-Info.plist -p ios /PATH/TO/dSYMs\n ```\n\n For usage notes and additional instructions about this script, run\n `upload-symbols` with the `--help` parameter."]]
