android中的应用程序有时会因java.lang.OutOfMemoryError而崩溃

我有一个在屏幕上画正方形的应用程序。用户可以使用手指（触摸事件）等移动正方形，增加其宽度和高度。用户还可以添加任意数量的正方形并单独移动它们

该应用程序在大部分情况下运行良好，但有时会崩溃，并给出以下错误

谁能告诉我怎么解决这个问题。谢谢：）

您可以将其写入您的

manifest.xml

文件

android:largeHeap="true"

---

这是内存泄漏的情况。首先，在这两个站点查看您的代码

at com.example.Square.isClicked(Square.java:478)05-09 11:32:49.488: E/AndroidRuntime(24826):    
at com.example.EditBubbleView$2.onTouch(EditBubbleView.java:378)

---

这两个方法是否同时被调用？？？？如果可能的话，把你的代码贴在这里，这样我们就可以看一看了

分析你的应用程序，看看它在哪里可能有内存泄漏。把你的代码放在崩溃的地方？你能显示错误中提到的代码吗

Square

和

editbubleview

堆栈跟踪显示您正在创建位图。您正在创建什么类型的位图？它有多大？可能超过设备上的可用内存。请将位图变量设置为全局变量。此外，在清单中将largeHeap值设置为true。如果问题仍然存在，则进行采样。这可能有效，但可能只是隐藏问题。最好先对其进行分析和测试，以确保它是必需的。文档还警告说，有必要了解你的应用程序是否真的需要更大的容量。这将是我的最后一次resort@Droider . 不要仅仅因为内存不足而请求一个大堆，并且需要一个快速修复方法。只有当您确切地知道所有内存被分配到哪里以及为什么必须保留内存时，才应该使用它。
