Copy link

you can use the built-in comparator (ResolveInfo.DisplayNameComparator) instead:

List<ResolveInfo> resInfo = pm.queryIntentActivities(dummy, 0);
Collections.sort(resInfo, new ResolveInfo.DisplayNameComparator(getPackageManager()));
List<HashMap<String, String>> metaInfo = new ArrayList<>();
for (ResolveInfo ri : resInfo) {
