android why the ResolveInfo got from resolveActivity() is different than from queryIntentActivities()

When looking at the ResolveInfo return from resolveActivity() and queryIntentActivities(),

why the ResolveInfo is different from these two calls for the same intent?

the viewIntent is Intent(Intent.ACTION_VIEW, Uri.parse(deeplinkData), and the one returned from resolveActivity has unrelated packagename/name:

ResolveInfo info = pm.resolveActivity(viewIntent, PackageManager.MATCH_DEFAULT_ONLY);

        System.out.println("+++ 111 resolveActivity(), info.activityInfo.packageName:  "+info.activityInfo.packageName+",\ninfo.activityInfo.name: "+info.activityInfo.name);

it has log:

+++ 111 resolveActivity(), info.activityInfo.packageName: android, 

info.activityInfo.name: com.android.internal.app.ResolverActivity

where using queryIntentActivities

List<ResolveInfo> resInfo = pm.queryIntentActivities(viewIntent, 0);
if (!resInfo.isEmpty()){
            for (ResolveInfo info : resInfo) {

                System.out.println("+++ queryIntentActivities(), info.activityInfo.packageName: "+ (info.activityInfo.packageName));
                System.out.println("+++ +++ queryIntentActivities(), info.activityInfo.name: "+ (info.activityInfo.name));

                ......
            }
        }

has log:

+++ queryIntentActivities(), info.activityInfo.packageName: com.client.android.debug
+++ +++ queryIntentActivities(), info.activityInfo.name: com.client.android.NewsActivity
+++ queryIntentActivities(), info.activityInfo.packageName: com.android.chrome
+++ +++ queryIntentActivities(), info.activityInfo.name: com.google.android.apps.chrome.IntentDispatcher

resolveActivity() returns the component that would be started if you call startActivity(). That will be:

• null if there is no match or you are not set up package visibility rules on Android 11+
• the activity that would be started from some app, if there is exactly one match or if the user chose a default
• the chooser activity, if there are 2+ matches and there is no default

In your case, you are getting the chooser activity (com.android.internal.app.ResolverActivity).
