Get Android NDK crash reports

If your Android app contains native libraries, you can enable full stack traces and detailed crash reports for your native code from Firebase Crashlytics with a few small updates to your app's build configuration.

Before you begin

To get started, first set up Crashlytics for Android by following the Getting Started guide.

Update your Gradle configuration

In your app-level build.gradle, enable the Crashlytics NDK flag and add the Crashlytics NDK dependency.

apply plugin: 'com.android.application'
apply plugin: 'io.fabric'

// Enable Crashlytics NDK reporting
crashlytics {
    enableNdk true
}

dependencies {
    // ...

    implementation 'com.google.firebase:firebase-core:17.0.1'
    implementation 'com.crashlytics.sdk.android:crashlytics:2.10.1'

    // Add the Crashlytics NDK dependency
    implementation 'com.crashlytics.sdk.android:crashlytics-ndk:2.1.0'
}

Upload native symbols

To produce readable stack traces from NDK crashes, Crashlytics needs to know about the symbols in your native binaries. Our Gradle plugin includes the crashlyticsUploadSymbols{variant} task to automate this process.

For method names to appear in your stack traces, you must explicitly invoke the crashlyticsUploadSymbols{variant} task after each build of your NDK library. For example:

./gradlew crashlyticsUploadSymbolsRelease

See your crash reports

Verify that Crashlytics is properly reporting NDK crashes by building your app, uploading symbols, and forcing a native crash. You’ll need to restart the app after it crashes for Crashlytics to send the report. You should see the crash in your Firebase console within a few minutes.
