融合位置 API 运行时权限错误
Posted
技术标签:
【中文标题】融合位置 API 运行时权限错误【英文标题】：Fused location API runtime permissions error 【发布时间】：2017-04-30 10:47:32 【问题描述】：我正在尝试获得访问该位置的权限并使用适用于 android 的 Fusedlocation 提供程序 API，但是，我的应用在打开时崩溃。我查看了 Google 开发人员文档并对相应的方法进行了适当的更改。
当我得到一个位置时，我会传递坐标并使用 SharedPreferences 存储它们。能否请您告诉我我在程序中没有处理什么或处理不正确？

【问题讨论】：
我现在已将堆栈跟踪添加到报告的问题中 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，但是在我调用的 onConnected() 方法中，检查权限（）验证了 ACCESS_FINE_LOCATION 权限？我错过了什么吗？ 【参考方案1】：Caused by: java.lang.IllegalStateException: GoogleApiClient is not connected yet.
在调用onConnected() 之前，您不能调用requestLocationUpdates()。但是，如果您确定自己拥有运行时权限，那么您已经在 onCreate() 中调用了 requestLocationUpdates()。
【讨论】：
你是对的。我已修复它，但仍然出现错误。我已经在上面发布了我的新堆栈跟踪并更新了程序，以便只维护位置上下文 @MaheshN：只有在 两个onConnected() 被调用 并且 你有权限之前，你才能调用 requestLocationUpdates()。现在，您在获得权限之前调用buildGoogleApiClient()，然后从onConnected() 调用requestLocationUpdates()（同样，在您获得权限之前）。 This sample app 演示了如何做到这一点。
你的 github 链接有帮助。我能够正确包含运行时权限。感谢您的帮助以上是关于融合位置 API 运行时权限错误的主要内容，如果未能解决你的问题，请参考以下文章
