Crashlytics Initialization Behavior

After integrating Firebase Crashlytics into your app, what happens if the app crashes before Crashlytics finishes initializing?

A The crash is recorded locally and sent to Firebase Crashlytics once initialization completes.

B The crash is not recorded or reported to Firebase Crashlytics.

C The app automatically restarts to complete Crashlytics initialization before reporting the crash.

D Crashlytics sends a partial crash report immediately, which is later completed.

💡 Hint

Think about what happens if the crash happens too early in the app lifecycle.

If the app crashes before Crashlytics initializes, the crash is not captured because Crashlytics is not yet ready to record or send crash data.

❓ Configuration

Correct Firebase Crashlytics Gradle Setup

Which of the following Gradle configurations correctly sets up Firebase Crashlytics in an Android app?

A Apply plugin 'com.google.gms.google-services' only and add 'com.google.firebase:firebase-crashlytics' dependency in app-level build.gradle.

B Add 'com.google.firebase:firebase-crashlytics' dependency only in project-level build.gradle without applying any plugin.

C Apply plugin 'com.google.firebase.crashlytics' in app-level build.gradle and add 'com.google.firebase:firebase-crashlytics' dependency.

D Add 'com.google.firebase:firebase-crashlytics' dependency in app-level build.gradle and apply plugin 'com.android.application' only.

💡 Hint

Remember that Crashlytics requires both a plugin and a dependency in the app module.

The Crashlytics Gradle plugin must be applied in the app-level build.gradle file, and the Crashlytics dependency must be added there as well for proper setup.

Crashlytics Data Privacy Compliance

Which practice ensures compliance with user privacy when using Firebase Crashlytics in your app?

A Avoid sending any user-identifiable information in crash reports and provide users with an option to opt out of crash reporting.

B Automatically collect user location data in crash reports without user consent.

C Disable Crashlytics data encryption to speed up crash report delivery.

D Send all user data including personal identifiers in crash reports to help debugging.

💡 Hint

Think about respecting user privacy and legal regulations.

To comply with privacy laws, apps should not send personal data in crash reports and must allow users to opt out of crash data collection.

❓ Architecture

Crashlytics Crash Report Flow

What is the correct sequence of steps for a crash report to be sent from a mobile app to the Firebase console using Crashlytics?

A 2,1,3,4

B 1,2,3,4

C 2,3,1,4

D 1,3,2,4

💡 Hint

Consider when Crashlytics can capture crashes and when it sends data.

Crashlytics must initialize first, then it can capture crashes locally. The crash report is sent on the next app launch, then processed and shown in the console.

Optimizing Crashlytics for Minimal Impact

Which approach best minimizes the impact of Firebase Crashlytics on app startup time and user experience?

A Send crash reports immediately on app crash without waiting for next app launch.

B Initialize Crashlytics synchronously at the very start of app launch to capture all crashes immediately.

C Disable Crashlytics initialization entirely on slow devices to improve startup time.

D Initialize Crashlytics asynchronously after critical app components have loaded and disable automatic data collection until user consent is given.

💡 Hint

Think about balancing crash data collection with app performance and user privacy.

Initializing Crashlytics asynchronously after critical components reduces startup delay. Disabling automatic collection until consent respects privacy and avoids unnecessary overhead.
