在过去的几天里，我读了很多类似的帖子，但没有一个专门回答这个问题。在使用混合地图进行大约 2 分钟的激进地图平移和缩放后，我开始遇到 OOM 问题。该应用程序似乎还在崩溃后保留了内存，因为在第一次失败后达到 OOM 所需的时间更少。我将代码缩小为仅具有 MapFragment 的 Activity，但仍然得到相同的 OOM。除了添加之外，我还使用 DDMS 和 MAT 来尝试隔离问题android:largeHeap="true"这只会延迟 OOM。屏幕重新定向不是问题，因为我正在设置android:screenOrientation="portrait"在我的清单中。任何帮助，将不胜感激。
2014年8月25日更新：这个问题应该会在 2013 年 5 月修复吗？
2014-09-06 更新：仍然没有成功，唯一好的选择是使用Normal代替Hybrid。 GC 似乎能够在没有图像的情况下跟上。
