Anyone else unable to publish their first Production release to Google Play because of the “16 KB memory page sizes” requirement?

Need help

Hi everyone,

I’m currently preparing to publish my first Android app built with Bubble to the Google Play Store.

Open Testing works fine, but when I submit my Production release, Google Play blocks the upload with this error:

“Your app does not support 16 KB memory page sizes.”

From what I understand, this is a new Google Play requirement related to WebAssembly (Wasm) and memory page size support. The problem is: this setting is applied during the build of the AAB, which is something Bubble controls. There is no option in the Play Console or Android Studio to fix it manually.

I tried re-uploading, checking App Integrity, signing settings, etc., but nothing helps. The AAB generated by Bubble simply doesn’t pass the new requirement.

So I’m wondering:

Is anyone else experiencing this?

Is it currently impossible to publish a Bubble-built app to Google Play Production until Bubble updates the Android exporter to support 16 KB page sizes?

If someone has successfully published a Production release recently, how did you solve this error?

At the moment, it seems like we may all be stuck unless Bubble updates the export tool.

Any insights or confirmations would be greatly appreciated.

Thanks!

This is a known issue with the new Google Play requirement for 16 KB memory page sizes that went into effect recently. Unfortunately, this is a limitation on the native build side that only the team at Bubble can fix.

The problem is that when Bubble generates the Android App Bundle (AAB), it needs to be compiled with flags that support 16 KB page sizes for WebAssembly/native code. Since you don’t have direct access to modify the build configuration or gradle files, you’re completely dependent on Bubble updating their mobile app export process.

What you can do:

  • Report this directly to Bubble support with your specific error screenshot so they prioritize a fix

  • Check if there’s already a bug report in the forum and upvote/comment on it to show this is affecting multiple users

  • For now, Open Testing works because Google hasn’t enforced this requirement there yet, but Production releases are blocked

This isn’t something you can fix on your end through re-uploading, changing signing settings, or app integrity checks. Bubble needs to update their build toolchain to comply with the new Google Play requirements. You may want to temporarily delay your Production launch until Bubble pushes an update.

Keep an eye on Bubble’s announcements or reach out to their support team for an ETA on when this will be addressed.

J’ai le même problème. Ma nouvelle version est bloquée par Google Play depuis une semaine environ. Malheureusement on n’y peut rien de notre côté. Seule une mise à jour de Bubble peut nous débloquer.
