退出应用程序时内存未清除

标签： android memory ondestroy

我已经浏览了几篇文章并注意到有时在应用程序退出时不会调用onDestroy（）。有时只调用onPause（）。我的整个事情是，当我使用后退按钮或finish（）函数退出我的应用程序时，一切看起来都很好。当我尝试重新打开我的应用时，它说：

12-14 04:09:59.457: E/GraphicsJNI(996): VM won't let us allocate 3279360 bytes

我也会粘贴整个日志。事情就是当它重新打开时，强制关闭。之后，我可以重新打开它。例如，每当我在Eclipse中重建它并通过模拟器运行它时，它都可以正常工作。但是，如果我在应用程序内关闭它并尝试重新打开它，那就是我遇到这个内存问题。我不确定什么不被清除，我真的希望你们中的一个人有一个解决方案，或者至少可以指出我正确的方向来解决这个问题，因为它真的让我头疼。如果你们需要更多信息，请告诉我。感谢。

尝试查看DDMS，它有一个Heap选项卡，告诉你内存分配。

窗口＆gt; Open Perspective＆gt;其他......

然后选择DDMS

修改

在我的一个应用程序中，我在Quit按钮中设置了此设置，它清除了Backstack并启动了应用程序中的第一个活动，只需将Main.class替换为您的第一个活动名称即可。然后，当您点击后退按钮时，应用退出

        Intent intent = new Intent(this, MainMenu.class);
        intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP); 
        intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
        startActivity(intent);
