Question

这个应用程序昨天工作，但今天早上开始工作时，我收到以下错误

Throwing OutOfMemoryError "Failed to allocate a 164 byte allocation with 44 free bytes and 44B until OOM" (recursive case)

我不知道发生了什么，或者为什么内存不足。这只是模拟器不能完美运行吗？或者这与我的应用有关吗？

我不知道您需要多少信息。如果您需要更多信息，请告诉我，我会提供。

更新：

我想这与垃圾收集器有关？请参阅下文

Answer 1

当您在项目中使用 REALLY BIG 图像时，通常会发生此类错误。尝试缩小图像尺寸，这个错误就解决了。

如果您不使用某些专业图像编辑软件（如Photoshop或Illustrator），则可以使用内置图像查看器执行此简单任务。

在Mac上，您可以使用预览应用程序缩小图像尺寸。

使用预览打开图像（只需双击图像，预览是默认应用程序）。
选择标记工具栏（看起来像公文包）。
点击“调整大小”按钮（看起来像一个正方形，两个箭头对面的角落）。
输入所需的宽度和高度。
点击确定，你就完成了=）

**我没有使用电脑，所以我无法解释如何解决这个问题，但它也应该非常简单。

我希望它有助于某人...

Answer 2

尝试这可以帮助您在清单文件中添加此标记。

<application android:largeHeap="true">
</application>

它将为您的应用分配大堆。祝你好运:)）

Answer 3

如果出现OutOfMemory异常，则会出现最大图像尺寸问题。

您可以调整图片大小，例如

 Picasso.with(context)
                            .load(new File(arrayList.get(position).getUrl()))
                            .networkPolicy(NetworkPolicy.NO_CACHE)
                            .memoryPolicy(MemoryPolicy.NO_CACHE)
                            .resize(300,300)
                            .error(R.drawable.placeholder_full_image)
                            .placeholder(R.drawable.placeholder_full_image)
                            .into(genericViewHolder.productImage_iv);

这对我有用

Answer 4

您的循环无限循环，因此您的应用内存不足。请尝试以下步骤 onCreate-＆GT; ChangeLanguage-＆GT; RestartActivity-＆GT; onCreate-＆GT; ChangeLanguage-＆GT; RestartActivity ...

你需要以某种方式结束它。

Answer 5

OutOfMemoryError：无法分配458字节分配1613776空闲字节和1575KB直到OOM;由于碎片而失败（对于一个新的缓冲区需要连续的空闲32768字节，其中最大的连续空闲4096字节）

因此，应用程序试图从它拥有的1613776个空闲字节中分配458个字节，但由于碎片而失败，它无法为新缓冲区找到32768个空闲字节。

这article解释说这是因为操作系统管理不好。我已经在使用Android 5和6的手机上的应用程序中看到了这个问题，我不认为作为开发人员我们可以做些什么来修复它。
