Check Android user's "when device is locked" notification settings

Question

On Android L, I would like show the user a notification on the lock screen only if the user settings is set to "show all notification content", otherwise the content will be pointless and I just prefer not to show the notification at all.

Any idea how to verify in code the user notification settings?

Thanks!

You need to read

Settings.Secure.LOCK_SCREEN_ALLOW_PRIVATE_NOTIFICATIONS = "lock_screen_allow_private_notifications"

Settings.Secure.LOCK_SCREEN_SHOW_NOTIFICATIONS = "lock_screen_show_notifications"

only if both are 1 then you need to show your notifications. But since these values are not part of public api, these might change in future, or might not work on all devices

int show_all = Settings.Secure.getInt(getContentResolver(),"lock_screen_allow_private_notifications", -1); 
int noti_enabled = Settings.Secure.getInt(getContentResolver(),"lock_screen_show_notifications", -1); 

if(show_all > 0 && noti_enabled > 0){
//post noti
}
