- Every uploaded bundle must include the Google Play Billing Library.
- Any app bundle that you upload on your pre-registration track must be in an executable APK format.
- Every uploaded bundle must include a one-year grace period.
- Any app bundles that you upload on your re-registration track are only used to specify your supported devices.
The correct answer is: Any app bundles that you upload on your pre-registration track are only used to specify your supported devices.
Here’s why:
- Purpose of App Bundles in Pre-registration: During the pre-registration phase, the app bundles you upload are not for distribution to users. They serve the sole purpose of defining the range of devices your app will support when it officially launches. This information helps Google Play filter pre-registration availability based on device compatibility.
The other options are incorrect:
- Google Play Billing Library Requirement: While the Google Play Billing Library is essential for apps with in-app purchases, it’s not a mandatory requirement for all app bundles uploaded on the pre-registration track.
- Executable APK Format: App bundles uploaded during pre-registration don’t need to be in an executable APK format. They are used for device compatibility information, not for immediate execution.
- One-Year Grace Period: There’s no mention of a one-year grace period associated with app bundles in the context of pre-registration.
The reference to the correct answer is found in Chapter “Optimize your store listing with experiments”, under the section “Set up experiments”. While not directly about pre-registration, the concept of using app bundles for specifying supported devices aligns with the information presented in this chapter.
