I understand that using 16K Pagesize will enhance memory efficiency (iOS uses 16K for a loooong time).

I have taken a quick look at the docs you posted. Looks like that requires an upgrade on NDK & AGP, and a complete review on the core source code on Pagesize. That's a lot of work.

So it won't be soon.

maybe all is right in 16K pagesize

Maybe.

The AGP plugin update is yet another painful job. Last time I did it the publish-to-maven script was broken and had to rollback.

@lingol 能直接使用NDK 或者cmake编译 出so库吗？这样就可以不升级AGP？

Maybe. It's not in our top priority though. I have checked with some senior Android devs and find out that no major brands turn on 16K on Android 15.

尊敬的开发者：
您好！目前小米已发布了Android 15预览版，开放平台也同步上线了带有新系统的远程真机，请开发者启动适配工作，并于2024年8月31日之前完成适配！
若您在2024年8月31日前未进行处理，我们将按照产品对用户的影响程度，采取相关措施以保障用户使用体验，包括但不限于“搜索标签提示”、“应用降级”、“分机型屏蔽”、“应用下架”。 请各位开发者及时调整，小米与您一起建设更好的Android 生态。

咨询了下小米工程师年内可能没计划进行16k对齐但是还是推荐先提前做好对齐工作，其他厂商还不了解。目前我们应用使用了mmkv在谷歌提供的模拟器上必崩。

[lingol]

new hash type from the future?

Looks like a bug in the system image. MMKV is built with NDK26, so no way has anything from the future.
May I suggest you make a bug report to the Google team?

编译一个支持16k的aar，目前我已经解决了该问题

@Nullifier1571 that's good to know, thank you.

你好，你是编译了一个支持16KB的MMKV版本了吗？方便共享吗？另外我看官方文档还是要改写代码的，比如代码里写死了4096的地方

了解的片面了, 适配android最新版本特性, 几乎是每个移动端团队每年必做的事情, 对现有app产生crash的变动 更会格外重视

也许吧。不过这并不是我们的首要任务。我咨询了一些资深 Android 开发人员，发现没有哪个大品牌会在 Android 15 上启用 16K。

[lingol]

Just so all you know, 16K is supported in the dev branch and will be available in the next version v2.0.

[mrousavy]

Nice work @lingol !

when will you release V2.0?

[lingol]

It should be rolled out this month.

[lingol]

v2.0.0 is out.
