MapFragment Google Maps API v2内存不足错误/内存泄漏

Question

过去几天我已经阅读了许多类似的帖子，但都没有明确回答这个问题。经过2分钟积极的地图平移和混合地图缩放后，我开始遇到OOM问题。该应用程序似乎在崩溃后仍保留在内存中，因为在第一次失败后需要较少的时间才能到达OOM。我将代码缩小到只有一个带有MapFragment的Activity，并且仍然获得相同的OOM。我已经使用DDMS和MAT来尝试和隔离问题，除了添加android:largeHeap="true"这只会延迟OOM。屏幕重新定位不是问题，因为我在我的清单中设置了android:screenOrientation="portrait"。任何帮助，将不胜感激。

更新2014年8月25日：This is supposed to be fixed back in May 2013?

更新2014年9月6日：仍然没有成功，唯一的好选择是使用Normal而不是Hybrid。 GC似乎能够保持没有图像。

Answer 1

尝试调用地图的onPause，的onResume，在相应片段的方法onLowMemory。

Answer 2

我遇到了这个问题，试图在演示模式下一次运行几个小时的应用程序。无论我尝试了什么，30分钟后，我都会看到这个崩溃，但没有可读的堆栈报告。

我尝试了很多不同的东西，但这是唯一对我有用的东西。这不是修复地图错误，但它保持我的应用程序崩溃：

<application 
    ... 
    android:largeHeap="true">
