 * 在框架的日常维护中，有很多人跟我反馈过框架有 Bug，但是经过排查和定位发现，这其中有 95% 的问题来自于调用者一些不规范操作导致的，这不仅对我造成很大的困扰，同时也极大浪费了很多小伙伴的时间和精力，于是我在框架中加入了很多审查元素，在 **Debug** 模式下，一旦有某些操作不符合规范，那么框架会直接抛出异常给调用者，并在异常信息中正确指引调用者纠正错误，例如：
 
-    1. 传入的 Activity 对象不是 FragmentActivity 的子类，框架会抛出异常，又或者传入的 Activity 的状态异常（已经 **Finishing** 或者 **Destroyed**），这种情况一般是在异步申请权限导致的，框架也会抛出异常，请在合适的时机申请权限，如果申请的时机无法预估，请在外层做好  Activity 状态判断再进行权限申请。
+    1. 传入的 Context 实例不是 Activity 对象，框架会抛出异常，又或者传入的 Activity 的状态异常（已经 **Finishing** 或者 **Destroyed**），这种情况一般是在异步申请权限导致的，框架也会抛出异常，请在合适的时机申请权限，如果申请的时机无法预估，请在外层做好  Activity 状态判断再进行权限申请。
 
     2. 如果调用者没有传入任何权限就申请权限的话，框架会抛出异常，如果调用者传入的权限不是危险权限或者特殊权限，框架也会抛出异常，因为有的人会把普通权限当做危险权限传给框架，系统会直接拒绝。
