Note description

RuntimePermissions: Required comment to comment on activity or fragment for which permission is to be obtained

NeedsPermission: Required annotation to annotate the method that needs to get permission

OnShowRationale: An unnecessary comment, prompting the user why this permission should be turned on. It is called when the user needs access permission after refusing it

OnPermissionDenied: Non-required comment, prompt when user chooses to reject

OnNeverAskAgain: Non-required comments, prompts after the user chooses not to ask again

Call to get permission: The auxiliary class xxxPermissionsDispatcher will be generated from the new compiler, which will be called through xxxPermissionsDispatcher. xxxWithCheck method, and the onRequestPermissionsResult method will be overridden, in which onRequestPermissionsResult method of onRequestPermissionsResult will be called, and the result of getting permission will be returned.
