Android Intent.createChooser application selector

Among the common Activity Action Intent constants, ACTION_PICK android.intent.action.PICK means "select data". Let's briefly share some usages of Intent.ACTION_PICK that I know:

(1) Call the gallery to get all local images:
Intent imageIntent = new Intent(Intent.ACTION_GET_CONTENT);
imageIntent.setType(“image/*”);
startActivityForResult(imageIntent, PICK_CODE); //PICK_CODE is a constant

(2), call local contact:
Intent intent = new Intent(Intent.ACTION_PICK);
intent.setType(ContactsContract.Contacts.CONTENT_TYPE);
startActivityForResult(intent, PICK_CONTACT);
(3), call music, get all local music files :
Intent audioIntent = new Intent(Intent.ACTION_GET_CONTENT);
audioIntent.setType(“audio/*”);
startActivityForResult(audioIntent, PICK_AUDIO);
(4), call video, get all local video files:
Intent videoIntent = new Intent(Intent .ACTION_GET_CONTENT);
videoIntent.setType("video/*");
startActivityForResult(videoIntent, PICK_VIDEO);

E.g:

 public static void jumpToChooser(Activity activity) {
        if (activity == null) {
            return;
        }
        Intent intent = new Intent(Intent.ACTION_PICK);
        intent.setType("image/*");

        PackageManager packageManager = activity.getPackageManager();
        List<ResolveInfo> resInfo = packageManager.queryIntentActivities(intent, 0);
        if (resInfo != null && (!resInfo.isEmpty())) {
            List<Intent> targets = new ArrayList<>();
            for (ResolveInfo info : resInfo) {
                Intent targeted = new Intent(Intent.ACTION_PICK);
                targeted.setType("image/*");
                ActivityInfo activityInfo = info.activityInfo;
                String packageName = activityInfo.packageName;
                if (activityInfo != null && packageName != null) {
                    if (packageName.contains(FILE_MANAGER) || packageName.contains(GALLERY_APP)) {//FILE_MANAGER,GALLERY_APP自定义包名
                        targeted.setPackage(packageName);
                        targets.add(targeted);
                    }
                }
            }
//            intent = Intent.createChooser(targets.remove(0), activity.getString(R.string.vrmake_setting_chooser_title));
            intent.putExtra(Intent.EXTRA_INITIAL_INTENTS, targets.toArray(new Parcelable[]{}));
        }
        activity.startActivityForResult(intent, PHOTO_REQUEST_GALLERY);
    }
