 Of course not! Permiso requires very little boilerplate, and therefore ```PermisoActivity``` does very little. If you don't want to subclass ```PermisoActivity```, all you have to do is make sure you do the two following things:
 
-* In ```onCreate()```, invoke ```Permiso.getInstance().setActivity(this)```.
+* In ```onCreate()``` and ```onResume()```, invoke ```Permiso.getInstance().setActivity(this)```.
 * Forward the results of ```Activity.onRequestPermissionsResult()``` to ```Permiso.getInstance().onRequestPermissionResult()```.
