After Android 12 update share intent not working in Samsung S10 device.This code is properly working in below Android version 12 devices but could not find the reason why in android 12 is filtering out.

        Intent sharingIntent = new Intent(android.content.Intent.ACTION_SEND);
        sharingIntent.setType("text/plain");
        // (Optional) If you want a preview title, set it with Intent.EXTRA_TITLE
        sharingIntent.putExtra(Intent.EXTRA_TITLE, str_title);
        sharingIntent.putExtra(Intent.EXTRA_TEXT, "https://www.cyranolab.media/msg/?q=507dddd6-8e43-11ec-9d11-061d7e6be791");
        sharingIntent.putExtra(Intent.EXTRA_SUBJECT, str_title);

        Intent receiver = new Intent(getActivityContext, UserSelectedShareBroadcast.class);
  PendingIntent pendingIntent;
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.S) {
            pendingIntent = PendingIntent.getActivity(getActivityContext,
                    0, receiver, PendingIntent.FLAG_UPDATE_CURRENT | PendingIntent.FLAG_IMMUTABLE);
        }else {
            pendingIntent = PendingIntent.getActivity(getActivityContext,
                    0, receiver, PendingIntent.FLAG_UPDATE_CURRENT);
        }

        Intent openInChooser = Intent.createChooser(sharingIntent, "Choose", pendingIntent.getIntentSender());
        List<LabeledIntent> intentList = new ArrayList<>();

        Intent externalEmailIntent = new Intent(getActivityContext, ExternalEmailShareActivity.class);
        externalEmailIntent.putExtra("programId", programId);
        externalEmailIntent.putExtra("sharedResourceId", sharedResourceId);
        externalEmailIntent.putExtra("INBOX", "Inbox");
        intentList.add(new LabeledIntent(externalEmailIntent, "Package Name", "Email to", R.drawable.ic_mail_outline));
        // convert intentList to array
        LabeledIntent[] extraIntents = intentList.toArray(new LabeledIntent[0]);

        openInChooser.putExtra(Intent.EXTRA_INITIAL_INTENTS, extraIntents);
        int REQUEST_SHARED_URL = 2;
        getActivityContext.startActivityForResult(openInChooser, REQUEST_SHARED_URL);
    }
