我的应用程序使用谷歌地图 V2。在其他设备上一切正常，但是当我在 HTC Wildfire S 上打开地图活动时，在地图导航几分钟后，我收到此错误：

我的地图上有数百个标记，这可能会使内存饱和？

我没有 Wildfire S 要检查，但我想如果你添加这个：

Toast.makeText(this, String.valueOf((Runtime.getRuntime().maxMemory() / 1024 / 1024)),
       Toast.LENGTH_SHORT).show();

在您的应用程序开头的某个位置并在设备上运行它，toast 将显示 16。这是您的应用程序可以分配的最大堆（以 MB 为单位）。可能您的其他测试设备有不同的限制。例如，我的 Desire HD（运行 PACman JellyBean）的限制是 48MB。对于 AVD，可以将此限制设置为配置的一部分。在某些情况下可以覆盖此限制以及如何增加 android 应用程序的堆大小？提供了一些很好的信息。

您是否需要这么多的 Ram 以及更多是另一个问题，如果没有更多关于代码和设计的信息，我们无法推测。但是，看看最近的问题android maps, markers and memory leaks。

最后，如果所有这些对您来说都是新的，那么仍然值得观看 Google IO 2011 演示文稿：Android 应用程序的内存管理。
