回答1:
The Android docs says:
Note: If the app targets API level 23 or higher, the app user must explicitly grant this permission to the app through a permission management screen. The app requests the user's approval by sending an intent with action ACTION_MANAGE_WRITE_SETTINGS. The app can check whether it has this authorization by calling Settings.System.canWrite().
So you have to request the user's approval explicitly by sending an intent with action ACTION_MANAGE_WRITE_SETTINGS.
回答2:
What is the error message that you are getting? Is the app crashing when you try to open it or set the airplane settings? If you are targetting >API 23, you need to explicitly ask for permissions during runtime, this is a change from earlier versions when the permission was granted once at install time.
