【问题描述】：
我的应用程序有一个很大的问题。 我们需要很多空间来进行位图转换，但是 直接在（应用程序的）启动时，大部分内存都被分配了未知的东西...... 您可以在下面找到 Xamarin Studio 的控制台输出。 什么可能触发如此大的分配？ 该应用程序在不同的设备上进行了测试，下面的输出来自最差的一个（三星 Galaxy S3）
这是我的 MainActivity 的 OnCreate：
protected override void OnCreate(Bundle bundle)
{
base.OnCreate(bundle);
SetContentView(Resource.Layout.Main);
}
控制台输出：
Forwarding debugger port 8808

感谢您的帮助！
编辑：
在清单中使用 LargeHeap 没有帮助。 当我加载完全没有布局的应用程序时，堆大小也增长到 19mb。
【问题讨论】：
-
HelloWorld 应用程序运行时内存（在 100MB 堆中）使用 ~15MB（在发布中）~14MB（在发布/aot/llvm 中）~16MB（在调试模式下，没有附加调试器），~17MB （在调试模式下），其中包括 Mono（基于 NDK）运行时、一些 .Net 程序集、Java 桥、启动活动等......在启动时听起来对我来说......
