Android Q is deprecating the "android.preference" library which Titanium's Ti.UI.Android.openPreferences() API uses.
Google's docs suggests that "android.preference" library is deprecated, not removed. So, we should first check that the deprecated usage still works while targeting API Level 29.
The best solution is to change Titanium to depend on the AndroidX libraries instead of the older Support libraries per
TIMOB-26472. This is a much bigger change that effects all modules that we may want to defer to a later date.
