java - Intent to choose between the camera or the gallery in Android

I'm trying to launch an intent to pick a image from the camera or the android's gallery. I checked THIS post and currently my code is near to work:

private Intent getPickIntent() {
    final List<Intent> intents = new ArrayList<Intent>();
    if (allowCamera) {
        setCameraIntents(intents, cameraOutputUri);
    }
    if (allowGallery) {
        intents.add(new Intent(Intent.ACTION_PICK, android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI));
    }

    if (intents.isEmpty()) return null;
    Intent result = Intent.createChooser(intents.remove(0), null);
    if (!intents.isEmpty()) {
        result.putExtra(Intent.EXTRA_INITIAL_INTENTS, intents.toArray(new Parcelable[] {}));
    }
    return result;
}

private void setCameraIntents(List<Intent> cameraIntents, Uri output) {
    final Intent captureIntent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
    final PackageManager packageManager = context.getPackageManager();
    final List<ResolveInfo> listCam = packageManager.queryIntentActivities(captureIntent, 0);
    for (ResolveInfo res : listCam) {
        final String packageName = res.activityInfo.packageName;
        final Intent intent = new Intent(captureIntent);
        intent.setComponent(new ComponentName(res.activityInfo.packageName, res.activityInfo.name));
        intent.setPackage(packageName);
        intent.putExtra(MediaStore.EXTRA_OUTPUT, output);
        cameraIntents.add(intent);
    }
}

When I set allowCamera=true it works correctly.

When I set allowGallery=true it shows the following chooser:

But if I set allowCamera=true and allowGallery =true the chooser shown is:

And if you select Android System then the first chooser is shown.

I'd like the chooser to be something like:

enter image description here

How can I "expand" the Android System option?

            Intent galleryintent = new Intent(Intent.ACTION_GET_CONTENT, null);
            galleryintent.setType("image/*");

            Intent cameraIntent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);

            Intent chooser = new Intent(Intent.ACTION_CHOOSER);
            chooser.putExtra(Intent.EXTRA_INTENT, galleryintent);
            chooser.putExtra(Intent.EXTRA_TITLE, "Select from:");

            Intent[] intentArray = { cameraIntent };
            chooser.putExtra(Intent.EXTRA_INITIAL_INTENTS, intentArray);
            startActivityForResult(chooser, REQUEST_PIC);
