我对这款Llama或Duck游戏进行了更新（对现有游戏进行了重新设计），由于outOfMemory错误，应用程序非常不一致地关闭。我已多次尝试清理内存，例如使用Intent的addFlags并研究不同的解决方案，但错误仍在继续。顺便说一句，这是两个屏幕中的一个（基本相同），在用户正在玩游戏时将在整个游戏中不断重建。目标是让用户选择在屏幕上显示哪种动物，如果正确，它们将继续播放。感谢任何帮助，谢谢。

答案 0 :(得分：2)
尝试设置
android:largeHeap="true"
在您的清单的<application>标记内;这将启动应用程序，并将更多内存分配给堆。
注意：启用此功能也不能保证可用内存的固定增加，因为某些设备受其总可用内存的限制。
如果你开始使用OOM，你的代码就会遇到根本问题 - 这只是一个绑定。
