Question

我正在为Android设备编写游戏，目前我的应用程序只能在平板电脑模拟器上成功运行。当我尝试在手机模拟器上运行应用程序或将其连接到我的设备时，它说“不幸的是，应用已经停止”。以下是我尝试在手机上运行应用程序时出现的错误。任何帮助将不胜感激。

OutOfMemoryError 是Android中最常见的问题，尤其是在处理Bitmaps(BitmapFactory,showing trace here)时。当由于内存空间不足而无法分配对象时，Java虚拟机（JVM）会抛出此错误，并且垃圾收集器也无法释放一些空间。

您可以在清单中添加这些行android:hardwareAccelerated="false"，android:largeHeap="true"，它适用于某些情况。

<application
    android:allowBackup="true"
    android:hardwareAccelerated="false"
    android:icon="@mipmap/ic_launcher"
    android:label="@string/app_name"
    android:largeHeap="true"
    android:supportsRtl="true"
    android:theme="@style/AppTheme">

我认为你应该在Androids Developer页面上阅读一些内容，特别是在这里：Displaying Bitmaps Efficiently

阅读所有5节课，然后重新编写代码。如果它仍然无法工作，我们将很高兴看到您在教程材料中做错了什么。

这里有一些SOF中这类错误的可能答案
