不幸的是应用程序已停止+ google 地图+无法确定Access_Fine_Location
Unfortunately application has stopped+ google map+can not determine Access_Fine_Location
我只是想按照本教程学习 (http://blog.teamtreehouse.com/beginners-guide-location-android)。我也为 AndroidManifest 添加了所需的权限。但是当我 运行 模拟器的应用程序停止时。在我的 logcat 中，它表示缺少 Access_fine_location 的权限；但这已经添加到清单中。谁能帮我找出问题所在？

好的，我的问题已经解决了。由于 ACCESS_FINE_LOCATION sdk 版本 23 存在一些问题，因此我选择了目标较低的 SDK。
从SDK 23开始，您需要在运行时请求权限。您可以在此处阅读有关运行时权限的信息：
http://developer.android.com/training/permissions/requesting.html
简单地说，在编写访问定位服务的逻辑之前，您需要检查应用程序是否具有所需的权限。在这种情况下 ACCESS_FINE_LOCATION 是一个危险的权限。所以用户必须明确授予权限。向用户解释为什么需要许可是一种很好的做法。用户响应请求后，判断权限是否被授予，然后进行相应处理。要么继续使用需要用户位置的代码，要么禁用它。
我只是想按照本教程学习 (http://blog.teamtreehouse.com/beginners-guide-location-android)。我也为 AndroidManifest 添加了所需的权限。但是当我 运行 模拟器的应用程序停止时。在我的 logcat 中，它表示缺少 Access_fine_location 的权限；但这已经添加到清单中。谁能帮我找出问题所在？

好的，我的问题已经解决了。由于 ACCESS_FINE_LOCATION sdk 版本 23 存在一些问题，因此我选择了目标较低的 SDK。
从SDK 23开始，您需要在运行时请求权限。您可以在此处阅读有关运行时权限的信息： http://developer.android.com/training/permissions/requesting.html
简单地说，在编写访问定位服务的逻辑之前，您需要检查应用程序是否具有所需的权限。在这种情况下 ACCESS_FINE_LOCATION 是一个危险的权限。所以用户必须明确授予权限。向用户解释为什么需要许可是一种很好的做法。用户响应请求后，判断权限是否被授予，然后进行相应处理。要么继续使用需要用户位置的代码，要么禁用它。
