我整天都在这。它昨天整天都很完美。所有我记得的是gradle让我交换网络（安全）下载的东西。大约一个小时后我去修建.. nada。恢复到最后一晚的检查，纳达。它可以在我的个人电话上运行但不是nexus 6.哎呀我甚至将####电话刷到5.1 nexus图像。纳达。清除所有缓存的gradle文件，将最小的SDK编号弄清楚。没有。哦，谷歌用了几个小时。
我建立，运行没有问题。使用我的地图CRASH导航到活动。虽然只是关于nexus，但我的笔记4没有崩溃。问题不是空指针，问题是

答案 0 :(得分：3)
你的问题在这里：
Location myLocation = locationManager.getLastKnownLocation(provider);
double latitude = myLocation.getLatitude();
根据您的堆栈跟踪，getLastKnownLocation()正在返回null。那是documented behavior。 getLastKnownLocation()仅适用于对位置进行乐观检查，如果它确实返回null，您可以在没有位置数据的情况下生活，或者use other methods to request location updates并在位置可用后使用该位置。< / p>
