我正在运行本教程，构建一个内置谷歌地图的Android应用程序。我的第一次运行是成功的，但是当我连续运行相同的东西时，它崩溃并且无法加载。
此处包括成功运行和不成功运行的日志：
- a non-exiting runtime exception
- the fatal unimplemented / null object reference exception
- a log about accessing hidden fields that's much longer than the equivalent message in the "correct" log
我不确定需要哪些数据，但这些问题有大小限制，所以请告诉我是否有任何其他信息可以提供帮助。
发射成功：
