* Add namespace to provider authority to prevent crashes on Android.
See katzer#1664

* Comment out android-sdk requirement since it's not being applied correctly.
See katzer#1561

* oreo bug fix, no smallIcon set in notification (katzer#1792)

* Update AssetUtil.java

Removing Resources.getSystem() to get resource ID because in android 8.1 (physical device) it fire an exception with the DEFALUT_ICON (res://icon) if no smallIcon is set in the notification schedule.
Changed also Options.java for small icon fallback

* Update Options.java

Removed resId = context.getApplicationInfo().icon
The application icon is set always and it is not able to select the resId = android.R.drawable.ic_popup_reminder. This is always set (API 1) and not showing ugly as app icon (notification small icon should be a silhouette)
