我试图获取访问位置的权限并使用Fusedlocation提供者android的API，但是，我的应用在打开时崩溃。我查看了Google开发者文档，并根据相应的方法进行了适当的更改。融合位置API运行时权限错误
当我得到一个位置时，我传递坐标并使用SharedPreferences存储它们。你能否让我知道我在程序中没有处理什么或处理不正确？

我已经将堆栈跟踪添加到报告的问题 –
我可以从错误中看到客户端必须具有ACCESS_FINE_LOCATION权限才能请求PRIORITY_HIGH_ACCURACY位置，但是我调用的是检查权限（）的onConnected（）方法，验证ACCESS_FINE_LOCATION权限？我错过了什么吗？ –
