我在谷歌广告以外的活动中没有使用任何图片。但我得到了java.lang.outofmemoryerror，app正在崩溃。
这里是logcat

我能知道为什么我收到java.lang.outofmemoy错误，我在做什么错误？
感谢：）

在Android中，每个应用程序都分配了 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，都会抛出OOM异常。
VM预算的值介于16MB到80MB之间。这取决于设备。
即使打印大量日志也会导致OOM问题，我已经对自己进行了测试。
同样在您的情况下，日志清楚地说明您在异步任务中的onPreExecute方法中添加的对话框正在泄漏。您是否在处理活动中的方向更改？
03-25 18：24：22.485：E / WindowManager（277）：活动com.netserv.Pungry.RestaurantsList泄露了最初添加到此处的窗口com.android.internal.policy.impl.PhoneWindow$DecorView@43f0d2e8
03-25 18：24：22.485：E / WindowManager（277）：android.view.WindowLeaked：Activity com.netserv.Pungry.RestaurantsList泄露了窗口com.android.internal.policy.impl.PhoneWindow $ DecorView @最初添加的43f0d2e8
如果您没有处理方向更改，那么对于每个方向更改，将再次创建活动并执行onCreate，这可能会一次又一次地触发异步任务。这也可以带来更高的内存利用率。
您的服务器响应有多大，我有过服务器响应的经验，这个响应是超过50,000个节点，从长远来看会导致问题。
您是否使用外部lib来解析XML数据？我建议编写一个简单的SAX解析器而不是它，它将减少对象创建的数量，并且控件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。只要超出内存，就会导致OutOfMemoryError。为了实现这一目标，您的应用程序中不一定必须包含图像。
之前已经报道过使用此库的问题。此线程中的解决方案可能对您有用：
