问题 How can I check if the device has low storage on Android 8 Oreo. I saw in the Android Documentation that the Intent.ACTION_DEVICE_STORAGE_LOW is deprecated in API 26.

I have referenced from those links: Notifications in specific time every day android, Android daily repeating notification at specific time of a day using AlarmManager, Android BroadcastReceiver on startup - keep running when Activity is in Background and much more...
