java - ANR 在由谷歌地图引起的 onCreate 中执行 setContentView？

Question

这一行代码：

setContentView(R.layout.main);

完成执行需要 2 到 7-8 秒，因为我在布局中添加了 Google Maps v2 片段，今天我在开发者控制台中收到了此 ANR：

可能与 setContentView 完成所需的长时间有关吗？有谁知道如何解决这个问题？提前致谢。

真正奇怪的行为是，这种缓慢的启动仅在您第一次启动应用程序时发生，或者如果您关闭它已经有几个小时了，而如果您使用后退按钮甚至最近的应用程序关闭它，那么它会在一秒钟内启动，很快，我真的不明白为什么。PS adMob 也是应用程序的一部分。
