Ok, I can partially answer my own question, in between posting and getting past the moderators, I worked out that I need a Context to call getContentResolver(), and whilst the AppWidgetProvider is not derived from Context, a Context is passed through to all the AppWidgetProvider calls such as onUpdate().
My other question still stands, is a ContentProvider the best way to get the data from my main app? I should point out that I need at most 3 numbers to be retreived which are quickly and simply calculated by my main app, so it is unlikely that there will be a ANR involved. Hence it seemed a direct call to the app's ContentProvider was more appropriate than launching another thread for a service?
