Understanding the Play Store App Signing

Which statement correctly describes the Play Store app signing process?

A You cannot use Google Play app signing if you want to update your app later.

B You must always sign your app with a debug key before uploading to Play Store.

C Play Store requires you to upload unsigned APKs and signs them automatically.

D Google manages the app signing key and signs your app after upload, improving security.

💡 Hint

Think about who holds the signing key for security and updates.

Google Play app signing means Google holds the signing key and signs your app after you upload an APK or AAB, which enhances security and allows easier key management.

Which of the following is NOT required when submitting an app to the Play Store?

A A minimum of 10 user reviews before publishing

B A high-resolution app icon in PNG format

C A signed APK or AAB file

💡 Hint

Consider what Play Store requires before publishing versus what happens after.

Versioning and Updates

What will happen if you upload an APK with a lower versionCode than the current Play Store version?

A The Play Store will accept it and replace the current version silently.

B The Play Store will reject the upload with an error about versionCode.

C The Play Store will publish both versions simultaneously.

D The Play Store will automatically increase the versionCode for you.

💡 Hint

Think about how Play Store ensures users get the latest app version.

Play Store requires each new upload to have a higher versionCode than the previous one to prevent downgrades and confusion.

Where in the Play Console do you upload your app bundle for release?

A Under the 'Release' section, inside 'Production' or other tracks

B In the 'Store Presence' tab under 'Store Listing'

C In the 'User Feedback' section

D In the 'Monetize' tab under 'Pricing & Distribution'

💡 Hint

Uploading the app bundle is part of releasing the app to users.

The 'Release' section is where you manage app versions and upload bundles or APKs for production or testing tracks.

Android Kotlin
