The '16 KB page sizes' issue wasn't resolved, even though the bundle details indicated that the latest version supports 16 KB page size

On August 28, I received an email from Google Play Support asking me to update and publish my app to support the 16KB Page Size requirement before November 1. I checked the bundle details and it confirmed that the current version did not support 16 KB Page Size.

As shown in the detail description and follow the guideline, I update the versions of the following components

• rootbeer lib = 0.1.1
• AGP = 8.5.1
• Google services = 4.4.3
• Kotlin = 2.0.0
• Gradle = 8.7
• Android Studio = Narwhal Feature Drop | 2025.1.2 Patch 2

Then I build and published the new version on September 2. The bundle details confirm that the latest version supports 16KB Page Size.

I tested my app with emulator with 'Pre-Release 16 KB Page Size Google Play Intel x86_64 Atom System Image' and everything looks normal.

To confirm that the emulator can be used to test the 16 KB Page Size, I tested with the previous version which does not support 16 KB Page Size and the app cannot started

However, after the review was completed, I returned to the issue page and found that the problem still persists.

I use 'Analyze APK' feature in Android Studio to check the issue. But the analysis results for the .apk and .aab files were different.

When I analyze .apk file, no issue found.

When I analyze .aab file, it said that the 16 KB Page Size issue exists.

I went through all the files, and none of them contain the issue.

I am wondering which part of the bundle might still contain the issue.

[Update for incorrect issue error in Android Studio]

Thank you @Risfat for pointing out the issue with Android Studio 2025.1.2. After update Android Studio to 2025.1.3 and re-analyzed the .aab file, the error is gone.

Yesterday I spent hours debugging my Flutter app. The .aab looked fine in Android Studio, but both the emulator (16kb) and Play Console showed errors. The issue is a bug in Android Studio Narwhal 2025.1.2, where AAB alignment isn’t checked properly (APKs are fine).

The fix: install the RC version (2025.1.3), upgrade NDK to r28, and update Gradle. I used gradle-8.14.2-all.zip since I couldn’t find the alpha mentioned.

Hope I save you some time if you are on the same situation. 😊
