问题描述

据我所知，每部 Android 手机都将所有应用的最大内存使用量限制为大约 16、24 或 32Mb.我刚刚看到有人在讨论 Dungeon Defenders 应用程序，该应用程序似乎使用了 256 Mb 的 RAM.

As far as I'm aware, each Android phones limits all apps to a maximum memory usage of about 16, 24 or 32Mb. I've just seen people discussing the app Dungeon Defenders which apparently seems to make use of 256 Mb of RAM.

这怎么可能?有谁知道这里发生了什么?访问这么多 RAM 会使我正在从事的某些项目更容易编写，所以我很想知道这个游戏在做什么.

How is this possible? Does anyone know what is going on here? Having access to that much RAM would make certain projects I'm working on much easier to write so I'm very interested to know what this game is doing.

推荐答案

在德国柏林的 droidcon 上，我听说您无法增加应用程序在 dalvik 端可以使用的 RAM 量.您可以使用本机端的所有可用内存，所以我猜命名的应用程序已经使用 NDK 在 C 中实现了本机的大量内存内容.这是我知道的唯一可能的解决方案...

On the droidcon in Berlin, Germany, I heard that you can't increase the amount of RAM an application can use on the dalvik side. You can use all available memory on the native side so I guess the named application have implemented heavy memory stuff native in C using the NDK. Thats the only possible solution I know...

更新这不是会议，而是与 Reto Meier 及其同事一起在我的大学访问 Google 实验室.

Update It wasn't the conference, it was a Google Lab visit at my university with Reto Meier and colleagues.
