Android google maps v2 API 突然停止工作？
Android google maps v2 API suddenly stops working?
更新
我和同事N6试过了。有效。所以我买了一个新的开箱即用的 N6。我安装了 Play 服务。它失败了。
我整天都在做这个。它昨天一整天都运行良好。我只记得 gradle 让我交换网络（安全）来下载一些东西。大约一个小时后，我去建造.. nada。回到昨晚的检查，nada。它适用于我个人的 phone，但不适用于 nexus 6。哎呀，我什至将 #### phone 闪烁到 5.1 nexus 图像。纳达。清除了所有缓存的 gradle 文件，调整了最小 SDK 编号。没有什么。哦，还有 googled 几个小时。
我建，运行没问题。使用我的地图 CRASH 导航至 activity。虽然只在 nexus 上，但我的 note 4 没有崩溃。问题不是空指针，问题是

您的问题在这里：
Location myLocation = locationManager.getLastKnownLocation(provider);
double latitude = myLocation.getLatitude();
根据您的堆栈跟踪，getLastKnownLocation() 正在返回 null。即 documented behavior. getLastKnownLocation() is only really good for optimistic checks on location, where if it does return null you either live without the location data or you use other methods to request location updates 并在该位置可用后使用该位置。

我和同事N6试过了。有效。所以我买了一个新的开箱即用的 N6。我安装了 Play 服务。它失败了。
我整天都在做这个。它昨天一整天都运行良好。我只记得 gradle 让我交换网络（安全）来下载一些东西。大约一个小时后，我去建造.. nada。回到昨晚的检查，nada。它适用于我个人的 phone，但不适用于 nexus 6。哎呀，我什至将 #### phone 闪烁到 5.1 nexus 图像。纳达。清除了所有缓存的 gradle 文件，调整了最小 SDK 编号。没有什么。哦，还有 googled 几个小时。
我建，运行没问题。使用我的地图 CRASH 导航至 activity。虽然只在 nexus 上，但我的 note 4 没有崩溃。问题不是空指针，问题是

Java代码。它主要是带有一些点击监听器的示例代码。我确实将地图更改为混合地图，从示例中...编辑我认为现在我看到了问题，这不是 google 示例。

您的问题在这里：
Location myLocation = locationManager.getLastKnownLocation(provider);
double latitude = myLocation.getLatitude();
根据您的堆栈跟踪，getLastKnownLocation() 正在返回 null。即 documented behavior. getLastKnownLocation() is only really good for optimistic checks on location, where if it does return null you either live without the location data or you use other methods to request location updates 并在该位置可用后使用该位置。
