【问题讨论】：
你在正确的节点下添加权限了吗？请将清单添加到问题中。 感谢您的回复。我不知道。我添加了我的清单。请帮助我。 看起来不错，不知道是什么问题。 【参考方案1】：在 android > 23 中你必须在运行时检查权限
Requesting Permissions at Run Time
【讨论】：
感谢您的回复。但是如何？请多多指导。 @Mahdi 按照上面的建议链接【参考方案2】：在 Manifest 中，您已声明您将向用户请求这些权限。但是，您必须了解，您实际上并没有通过在 Manifest 中声明它们来获得这些权限。您需要在运行时请求这些权限。
从 Android 6.0（API 级别 23）开始，用户可以随时撤消任何应用的权限，即使该应用的目标 API 级别较低。因此，即使该应用昨天使用了相机，也不能假设它今天仍然拥有该权限。
来源：Official Website
我还没有完全看完你的代码。但是，关于解决您发布的错误，解决方案非常简单。您需要做的就是在运行时请求 android.permission.CALL_PHONE。
最好的指南可能是official website。这只是10分钟的阅读时间。
