Technical request for guidance on enabling 16 KB page size support in Unreal Engine 5.4 using NDK r25b

Hello Team,

As you may know, Google Play now requires the use of 16 KB page sizes, as stated in the following document: Support 16 KB page sizes | Compatibility | Android Developers

We also noticed that your team has recently released support for this requirement in Unreal Engine 5.6.

We would like to ask about two points as outlined below:

  1. In our case, we are still using Unreal Engine 5.4 for our game. Could you please advise which components or changes we should consider merging from Unreal Engine 5.6 into 5.4 in order to support the 16 KB page size requirement?
  2. Since the 16 KB page size support requires NDK 28 or later, we would like to ask how we can enable this functionality in Unreal Engine when using an older NDK version (we are currently using NDK r25b). Is there any workaround or configuration that allows us to proceed without upgrading the NDK?

Let me know if you need more info.

Thanks a lot,

Nga Le

Hi Nga,

16K page size support is supported under r26b as per Google documentation here: https://developer.android.com/guide/practices/page-sizes#compile-r26-lower

Here’s a list of CLs for UE 5.6 that would need to be backported if staying on UE 5.4 is necessary for your project:
