嗨，你好好读一下与android中的grow heap有关的错误

08-13 21:46:22.382: I/dalvikvm-heap(10859): Grow heap (frag case) to 20.578MB for 2400016-byte allocation

下面是日志（已过滤），其中我多次退出我的应用程序并一遍又一遍地重新开始。正如你可以看到的那样，每次重启都会增加堆。怎么可能？完全退出时，应该不会清除应用堆？

如果我对代码进行任何更改并重新启动应用程序，则堆将重置为其原始值。这种行为是否正常？

每次我在应用程序中切换活动时，也会发生相同的堆增长。我在andengine中编写了我的应用程序。我的堆高达80MB，加载速度更快，堆积更大。

这就像关闭应用程序后保留的内存泄漏，在应用程序中我确实使用sharedPreferences来保存。但我没有看到这可以产生什么影响。有什么想法吗？

Android应用程序不会简单地关闭，请参阅以下关于该主题的精彩博文： http://blog.radioactiveyak.com/2010/05/when-to-include-exit-button-in-android.html

堆增长是因为你的应用程序没有关闭，它只是隐藏了。实际上，你似乎确实有内存泄漏。更改变量名称时堆会缩小，因为生成了新的apk，手机上的应用程序被终止并重新安装了应用程序。

重启应用程序时Android堆增长
