除了谷歌广告，我没有在我的活动中使用任何图片。但我得到 java.lang.outofmemoryerror 并且应用程序正在崩溃。

这是日志猫

}

我能知道为什么我收到 java.lang.outofmemoy 错误以及我在做什么错误吗？

谢谢：）

在 Android 中，每个应用程序都分配有一个VM 预算。VM 预算是任何应用程序可以使用的最大内存量。此内存限制包括所有内容、位图（即使它是在外部堆上创建的）、对象等。每当应用程序超出此限制时，就会引发 OOM 异常。

VM 预算的值范围从 16MB 到 80MB 或更多。这取决于设备。

即使打印大量日志也会导致 OOM 问题，我自己已经测试过了。

同样在您的情况下，日志清楚地表明您在onPreExecute异步任务中添加的对话框正在泄漏。您是否正在处理活动中的方向变化？

03-25 18:24:22.485: E/WindowManager(277): 活动 com.netserv.Pungry.RestaurantsList 泄露了最初添加在这里的窗口 com.android.internal.policy.impl.PhoneWindow$DecorView@43f0d2e8

如果您不处理方向更改，那么对于方向的每次更改，将再次创建并onCreate执行活动，这会导致异步任务被一次又一次地触发。这也可能导致更高的内存利用率。

你的服务器响应有多大，我有过服务器响应的经验，它有 50,000 多个节点，从长远来看会导致问题。

您是否使用外部库来解析 XML 数据？我建议编写一个简单的 SAX 解析器而不是那个，它会减少对象创建的数量，并且控制保留在您自己的代码中

问题很可能是您使用 ksoap2 通过 SOAP 请求发送/接收大量数据。OutOfMemoryError每当超出内存时就会引起。您的应用程序中没有必要必须存在图像才能发生这种情况。

以前曾报告过使用此库的此类问题。此线程中的解决方案可能对您有用：
