首先，我使用的是运行 android 4.4(kitkat) 的 Nexus 7(2013 年的 1080p 屏幕)，并使用 eclipse 和适用于 windows 的 adb 插件(我认为是 64 位)。我的应用程序 minSdkVersion 设置为 11，并且只能在横向模式下运行。
问题是我的应用程序运行一段时间后，我不断收到 OOM 错误。我的 dalvik 堆保持恒定在 25~MB 左右，但使用 Debug.getNativeHeapAllocatedSize() 和 Debug.getNativeHeapSize() 它说我的 native 堆大小不断增加，直到应用程序因 OOM 错误而崩溃。
我通过在我的 list 中声明 android:hardwareAccelerated="true"并在我的 SurfaceView 构造函数中使用 setLayerType( View.LAYER_TYPE_HARDWARE , null ) 将其设置为硬件加速来使用硬件加速。
(使用 setLayerType( View.LAYER_TYPE_HARDWARE , null ) 是我的问题，我删除了它并且内存泄漏停止了)。
奇怪的是，一旦我按下主页按钮然后返回我的应用程序， native 堆就会重置回其初始值。
我从 LogCat 中的这些消息中证明了 dalvik 堆保持不变并且 native 堆正在增长:
debug.native 堆:分配了 191.73MB 中的 191.45MB(0.28MB 空闲) debug.VM 堆内存:分配 23.00MB VM 堆大小:31.00MB MaxHeapSize:192.00MB : availMemory 634.95MB , lowMemory? false ，阈值 96.00MB : Canvas .isHardwareAccelerated() = true : GC_FOR_ALLOC 释放 4566K，30% 释放 22608K/32236K，暂停 32ms，总计 32ms : 调试。 ================================= : debug.native heap : 分配 197.01MB of 197.27MB (0.26MB free) : debug.VM 堆内存:分配 22.00MB VM 堆大小:31.00MB MaxHeapSize:192.00MB : availMemory 629.38MB , lowMemory? false , 阈值 96.00MB
然后，一旦 native 堆已满，我就会收到错误消息:

我想知道如何防止 native 堆内存泄漏，因为我不知道如何在 dalvik 堆上分配 native block 。
我顺便解决了这个问题，只是想把它写出来以帮助其他人，因为我搜索了几天都找不到答案。
最佳答案
我花了几天时间寻找解决方案，以解决为什么我的 native 堆在增加而我的 dalvik 堆保持不变。在阅读了许多问题和 android 文档页面后，我最终尝试关闭硬件加速，因为我已经遇到了与这两者相关的 OOM 问题。
我从 SurfaceView 中删除了 setLayerType( View.LAYER_TYPE_HARDWARE , null ) 行，问题就消失了。我根据一些关于尝试打开硬件加速的建议提出了一些建议后添加了该行，但我从来没有真正理解我在那里做了什么。出于某种原因，该行导致大约 1mb/2 秒被添加到 native 堆，直到我的程序崩溃。
因此，对于任何正在寻找问题解决方案的人来说，一次尝试一件事，并在将其复制粘贴到您的代码之前了解您的尝试。
我仍然不知道为什么这会导致 native 堆不断增加。
我希望这对遇到 OOM native 堆问题的人有所帮助。
