 /**
     * Retrieve a set of activities that should be presented to the user as
     * similar options.  This is like {@link #queryIntentActivities}, except it
     * also allows you to supply a list of more explicit Intents that you would
     * like to resolve to particular options, and takes care of returning the
     * final ResolveInfo list in a reasonable order, with no duplicates, based
     * on those inputs.
     *
     * @param caller The class name of the activity that is making the
     *               request.  This activity will never appear in the output
     *               list.  Can be null.
     * @param specifics An array of Intents that should be resolved to the
     *                  first specific results.  Can be null.
     * @param intent The desired intent as per resolveActivity().
     * @param flags Additional option flags.  The most important is
     * {@link #MATCH_DEFAULT_ONLY}, to limit the resolution to only
     * those activities that support the {@link android.content.Intent#CATEGORY_DEFAULT}.
     *
     * @return A List<ResolveInfo> containing one entry for each matching
     *         Activity. These are ordered first by all of the intents resolved
     *         in specifics and then any additional activities that
     *         can handle intent but did not get included by one of
     *         the specifics intents.  If there are no matching
     *         activities, an empty list is returned.
     *
     * @see #MATCH_DEFAULT_ONLY
     * @see #GET_INTENT_FILTERS
     * @see #GET_RESOLVED_FILTER
