Hi, I'm currently working on an app and would like to use this code if possible?

I found that when calling targetedIntents.get(0)/targetedIntents.remove(0) that item is added back to the list of apps as the last one. Since there is the sort called, this will mess up the sorted list.

I, instead, used the following:

Intent chooserIntent = Intent.createChooser(targetedIntents.remove(targetedIntents.size() -1), title);

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) {
