问题
I wonder if there is some way to being notified when user changes permission in app settings on Android 6.0. I was looking for this answer with no luck. Do you know if it is possible with broadcast receiver and some specific Intent? Or maybe there is some hack to achieve this?
回答1:
according to this answer, there is no any broadcast/event that you can intercept when permission revoked from the settings screen by the user.
but the "good" news, in assumption that it's your concern - your process will be terminated automatically by the system if there will be any changes to the permission status while your app process was alive
回答2:
You can keep track of this by using the AlarmManager to periodically check for the permissions your're interested in (for example every 30 seconds) and compare it to the value you saw the last time (saved in SharedPreferences for example). In the worst case you won't get updates within the timer interval, however it should be very unlikely that the user changes a permission multiple times within a short time interval.
Keep in mind that you have to start the periodical checks when the device boots up (android.intent.action.BOOT_COMPLETED).
