Understanding Play Store App Signing

Which of the following best describes the purpose of app signing in the Play Store submission process?

A It removes unused code to optimize performance.

B It compresses the app to reduce download size.

C It automatically translates the app to multiple languages.

D It verifies the identity of the app developer and ensures app integrity.

💡 Hint

Think about security and trust when users download apps.

App signing uses a digital certificate to confirm the app comes from the developer and hasn't been tampered with.

Play Store Listing Requirements

Which of these is NOT required when creating a Play Store listing for your React Native app?

A App screenshots showing the app interface.

B The source code of your app.

C A privacy policy URL if your app collects user data.

D A short and full description of the app.

💡 Hint

Think about what users and Google need to see, not what developers share.

Google Play requires screenshots, descriptions, and privacy policy but not the app's source code.

Handling Version Codes in Play Store Submission

You have submitted versionCode 5 of your React Native app to the Play Store. What happens if you try to upload an APK or AAB with versionCode 4?

A The Play Store accepts it but users will not receive updates.

B The Play Store accepts it and replaces versionCode 5 with 4.

C The Play Store rejects the upload because versionCode must increase with each release.

D The Play Store automatically increments the versionCode to 6.

💡 Hint

Think about how updates should always move forward, not backward.

Play Store requires each new upload to have a higher versionCode than previous ones to avoid confusion.

Play Store Release Tracks Usage

Which Play Store release track allows you to test your React Native app with a small group of users before a full public release?

A Closed testing track

B Production track

C Beta testing track

D Internal testing track

💡 Hint

Consider which track limits access to a specific group rather than everyone.

Closed testing lets you release your app to a limited group for feedback before wider release.

Troubleshooting Play Store Submission Errors

You receive this error when uploading your React Native app bundle: "Upload failed: Your app bundle is missing the required native debug symbols." What is the most likely cause?

A You did not generate or include the native debug symbols (mapping files) during build.

B Your app bundle size exceeds the Play Store limit.

C You forgot to increment the versionName in build.gradle.

D Your app icon does not meet Play Store size requirements.

💡 Hint

Debug symbols help with crash reporting and must be included in the upload.

Native debug symbols are needed for Play Store to process crash reports; missing them causes upload failure.
