Question

我的应用程序存在很大问题。我们需要很多空间来进行位图转换，但是直接在Startup（应用程序）的大部分内存获取与未知的东西分配... 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测试，下面的输出来自最差的一个（三星Galaxy S3）

这是我对MainActivity的OnCreate：

protected override void OnCreate(Bundle bundle)
{
    base.OnCreate(bundle);
    SetContentView(Resource.Layout.Main);
}

控制台输出：

感谢您的帮助！

编辑：

在Manifest中使用LargeHeap不起作用。当我在没有布局的情况下加载应用程序时，堆大小也增加到19mb。

Answer 1

如果您没有使用自定义Application类且setContentView()，则有一行代码可能导致内存分配。您可能在Layout xml上有大图像或图像太多。尝试简化布局xml或使用较小的图像。如果您没有内存不足，则不需要更改此内容;但是你需要更多的空间来进行图像操作，所以你可以这样做（但不建议这样做）：android:largeHeap="true"

Answer 2

我发现了问题。在我的drawable文件夹不是正确的Icon.png。我使用的Icon的分辨率为708x708。我用一个较小的替换它，现在它可以... 谢谢Ercan让我朝着正确的方向前进。
