# @capacitor-firebase/crashlytics[¶](#capacitor-firebasecrashlytics "Permanent link")

Unofficial Capacitor plugin for [Firebase Crashlytics](https://firebase.google.com/docs/crashlytics/).[1](#fn:1)

[ ![Deliver Live Updates to your Capacitor app with Capawesome Cloud](../../../assets/external/cloud.capawesome.io/assets/banners/cloud-build-and-deploy-capacitor-apps.69628c3f.png) ](https://cloud.capawesome.io/) 

## Newsletter[¶](#newsletter "Permanent link")

Stay up to date with the latest news and updates about the Capawesome, Capacitor, and Ionic ecosystem by subscribing to our [Capawesome Newsletter](https://cloud.capawesome.io/newsletter/).

## Compatibility[¶](#compatibility "Permanent link")

| Plugin Version | Capacitor Version | Status         |
| -------------- | ----------------- | -------------- |
| 8.x.x          | \>=8.x.x          | Active support |
| 7.x.x          | 7.x.x             | Deprecated     |
| 6.x.x          | 6.x.x             | Deprecated     |
| 5.x.x          | 5.x.x             | Deprecated     |
| 1.x.x          | 4.x.x             | Deprecated     |

## Installation[¶](#installation "Permanent link")

You can use our **AI-Assisted Setup** to install the plugin. Add the [Capawesome Skills](https://github.com/capawesome-team/skills) to your AI tool using the following command:

`[](#%5F%5Fcodelineno-0-1)npx skills add capawesome-team/skills --skill capacitor-plugins
`

Then use the following prompt:

`` [](#%5F%5Fcodelineno-1-1)Use the `capacitor-plugins` skill from `capawesome-team/skills` to install the `@capacitor-firebase/crashlytics` plugin in my project.
 ``

If you prefer **Manual Setup**, install the plugin by running the following commands and follow the platform-specific instructions below:

`[](#%5F%5Fcodelineno-2-1)npm install @capacitor-firebase/crashlytics
[](#%5F%5Fcodelineno-2-2)npx cap sync
`

Add Firebase to your project if you haven't already ([Android](https://github.com/capawesome-team/capacitor-firebase/blob/main/docs/firebase-setup.md#android) / [iOS](https://github.com/capawesome-team/capacitor-firebase/blob/main/docs/firebase-setup.md#ios)).

### Android[¶](#android "Permanent link")

#### Crashlytics Gradle plugin[¶](#crashlytics-gradle-plugin "Permanent link")

First, add the dependency for the Crashlytics Gradle plugin to your root-level (project-level) Gradle file (`<project>/build.gradle`):

`[](#%5F%5Fcodelineno-3-1)buildscript {
[](#%5F%5Fcodelineno-3-2)    dependencies {
[](#%5F%5Fcodelineno-3-3)+       // Add the dependency for the Crashlytics Gradle plugin
[](#%5F%5Fcodelineno-3-4)+       classpath 'com.google.firebase:firebase-crashlytics-gradle:2.9.9'
[](#%5F%5Fcodelineno-3-5)    }
[](#%5F%5Fcodelineno-3-6)}
`

Add the Crashlytics Gradle plugin to your module (app-level) Gradle file (usually `<project>/<app-module>/build.gradle`):

`[](#%5F%5Fcodelineno-4-1)apply plugin: 'com.google.firebase.crashlytics'
`

#### Variables[¶](#variables "Permanent link")

If needed, you can define the following project variable in your app’s `variables.gradle` file to change the default version of the dependency:

* `$firebaseCrashlyticsVersion` version of `com.google.firebase:firebase-crashlytics` (default: `20.0.3`)

This can be useful if you encounter dependency conflicts with other plugins in your project.

### iOS[¶](#ios "Permanent link")

To generate human readable crash reports, Crashlytics needs your project's debug symbol (dSYM) files. The following steps describe how to automatically upload dSYM files to Firebase whenever you build your app:

1. Open your project's Xcode workspace, then select its project file in the left navigator.
2. From the **TARGETS** list, select your main build target.
3. Click the **Build Settings** tab, then complete the following steps so that Xcode produces dSYMs for your builds.
4. Click **All**, then search for `debug information format`.
5. Set **Debug Information Format** to `DWARF with dSYM File` for all your build types.
6. Click the **Build Phases** tab and complete the following steps:
7. Click the **+** button, then select **New Run Script Phase**.  
Make sure this new **Run Script** phase is your project's last build phase; otherwise, Crashlytics can't properly process dSYMs. 2\. Expand the new **Run Script** section. 3\. In the script field (located under the _Shell_ label), add the run script based on your package manager:  
**CocoaPods:**  
`[](#%5F%5Fcodelineno-5-1)"${PODS_ROOT}/FirebaseCrashlytics/run"  
`  
**Swift Package Manager:**  
`[](#%5F%5Fcodelineno-6-1)"${BUILD_DIR%/Build/*}/SourcePackages/checkouts/firebase-ios-sdk/Crashlytics/run"  
`
8. In the **Input Files** section, add the paths for the locations of the following files based on your package manager:  
**CocoaPods:**  
`[](#%5F%5Fcodelineno-7-1)${DWARF_DSYM_FOLDER_PATH}/${DWARF_DSYM_FILE_NAME}/Contents/Resources/DWARF/${TARGET_NAME}  
`  
`[](#%5F%5Fcodelineno-8-1)$(SRCROOT)/$(BUILT_PRODUCTS_DIR)/$(INFOPLIST_PATH)  
`  
**Swift Package Manager:**  
`[](#%5F%5Fcodelineno-9-1)${DWARF_DSYM_FOLDER_PATH}/${DWARF_DSYM_FILE_NAME}  
`  
`[](#%5F%5Fcodelineno-10-1)${DWARF_DSYM_FOLDER_PATH}/${DWARF_DSYM_FILE_NAME}/Contents/Resources/DWARF/${PRODUCT_NAME}  
`  
`[](#%5F%5Fcodelineno-11-1)${DWARF_DSYM_FOLDER_PATH}/${DWARF_DSYM_FILE_NAME}/Contents/Info.plist  
`  
`[](#%5F%5Fcodelineno-12-1)$(TARGET_BUILD_DIR)/$(UNLOCALIZED_RESOURCES_FOLDER_PATH)/GoogleService-Info.plist  
`  
`[](#%5F%5Fcodelineno-13-1)$(TARGET_BUILD_DIR)/$(EXECUTABLE_PATH)  
`  
If you have `ENABLE_USER_SCRIPT_SANDBOXING=YES` and `ENABLE_DEBUG_DYLIB=YES` in your project build settings, also include:  
`[](#%5F%5Fcodelineno-14-1)${DWARF_DSYM_FOLDER_PATH}/${DWARF_DSYM_FILE_NAME}/Contents/Resources/DWARF/${PRODUCT_NAME}.debug.dylib  
`

## Configuration[¶](#configuration "Permanent link")

No configuration required for this plugin.

## Test your implementation[¶](#test-your-implementation "Permanent link")

[Here](https://firebase.google.com/docs/crashlytics/force-a-crash) you can find more information on how to test the Firebase Crashlytics implementation. Among other things, you will find information on how to correctly [adjust the project's debug settings](https://firebase.google.com/docs/crashlytics/force-a-crash?platform=ios#adjust%5Fyour%5Fprojects%5Fdebug%5Fsettings) under iOS and how to [test it out](https://firebase.google.com/docs/crashlytics/force-a-crash?platform=ios#test%5Fit%5Fout).

If you get obfuscated crash reports for iOS, make sure you have [initialized Crashlytics](https://firebase.google.com/docs/crashlytics/get-started?platform=ios#initialize-crashlytics) correctly and take a look at [this guide](https://firebase.google.com/docs/crashlytics/get-deobfuscated-reports?platform=ios), which provides some ways to troubleshoot if Crashlytics can't find your app's dSYM.
