我有一个应用程序在KitKat上运行得很好但是当我将手机升级到API21（Lollipop）时，我遇到了这个奇怪的失败。我认为这是一个谷歌bug，但想知道是否有其他人看过它并找到了解决方法？我正在执行以下简单的代码（我的类扩展了SupportMapFragment，fyi）：
public CameraPosition getCurrentCameraPosition() {
return mMap != null ? mMap.getCameraPosition() : null;
}
然而mMap.getCameraPosition()导致了这个例外：

如果你想知道为什么我使用成员变量引用GoogleMap而不是getMap() ....我在这里使用getMap()但升级后到Lollipop，它开始返回null（尽管它在GoogleMap中返回了正确的onCreateView）。
我现在猜测它正在返回null，因为它遇到了这个OutOfMemoryException，在catch块中捕获了它，并返回null。
