这是一个MapView Bug吗？

Question

我正在实施一个使用Google地图的应用.在调试过程中,我发现了一个有趣的错误,您可以轻松地重现(我希望).如果您从Google测试Hello MapView示例:

错误:如果您快速向任何方向滑动(尝试对角线方向),在一段时间内,您可能会收到以下错误:

地图崩溃了.不知道怎么解决这个问题？

Answer 1

认为 Google 地图因OutOfMemoryError崩溃，我在 HTC Wildfire 上遇到过几次。它可以在堆内存较小的设备上轻松重现。当您快速滑动（调整大小）时，您将超出所有堆。认为垃圾收集器在某些情况下无法如此快地释放内存，并且您会遇到内存不足的情况。
