Convert String with multiple values to arraylist and add programmatically to a spinner?

((I'm using the browser to enter the site, because app here is in trouble)

I'm pulling multiple results from a video formats on YouTube. However, when I step into the spinner, it only passes one result, which is usually the first, which is usually the audio. Then the (remaining) video formats of all spinner results do not appear.

Edited: First I see if the app received any valid YouTube link:

    // Check how it was started and if we can get the youtube link
    if (savedInstanceState == null && Intent.ACTION_SEND.equals(getIntent().getAction())
        && getIntent().getType() != null && "text/plain".equals(getIntent().getType())) {

        String ytLink = getIntent().getStringExtra(Intent.EXTRA_TEXT);

        if (ytLink != null
            && (ytLink.contains("://youtu.be/") || ytLink.contains("youtube.com/watch?v="))) {
            youtubeLink = ytLink;
            // We have a valid link
            getUrl(youtubeLink);
        } else {
            Toast.makeText(this, R.string.app_name, Toast.LENGTH_LONG).show();
            finish();
        }
    } else if (savedInstanceState != null && youtubeLink != null) {
        getUrl(youtubeLink);
    } else {
        //finish();
    }
}

Then I take the link to convert and expand the app action (formats) and then I send the result to a new method so that the spinner download options are added:

private void getUrl(String youtubeLink) {
    new YouTubeExtractor(this) {
        @Override
        public void onExtractionComplete(SparseArray<YtFile> ytFiles, VideoMeta vMeta) {
            if (ytFiles == null) {
                // Something went wrong we got no urls. Always check this.
                finish();
                return;
            }
            // Iterate over itags
            for (int i = 0, itag; i < ytFiles.size(); i++) {
                itag = ytFiles.keyAt(i);
                // ytFile represents one file with its url and meta data
                YtFile ytFile = ytFiles.get(itag);

                // Just add videos in a decent format => height -1 = audio
                if (ytFile.getFormat().getHeight() == -1 || ytFile.getFormat().getHeight() >= 360) {
                }
                    initSpinner(vMeta.getTitle(), ytFile);
                }
           }
    }.extract(youtubeLink, true, false);
}

New method for adding * format options in spinner:

public void initSpinner(final String videoTitle, final YtFile ytfile){
    spinner = (Spinner) findViewById(R.id.spinner);

    // Display some buttons and let the user choose the format
    String opcFrmt = (ytfile.getFormat().getHeight() == -1) ? "Audio " +
        ytfile.getFormat().getAudioBitrate() + " kbit/s":
    ytfile.getFormat().getHeight() + "p";
    opcFrmt += (ytfile.getFormat().isDashContainer()) ? " dash" : "";

    // Spinner click listener
    spinner.setOnItemSelectedListener(this);

    // Spinner Drop down elements
    List<String> strList = new ArrayList<String>();
    //return the list representation of array

    strList.add(opcFrmt);
    strList.add(opcFrmt);

    // Creating adapter for spinner
    ArrayAdapter<String> dataAdapter = new ArrayAdapter<String>(this, android.R.layout.simple_spinner_item, strList);

    // Drop down layout style - list view with radio button
    dataAdapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);

    // attaching data adapter to spinner
    spinner.setAdapter(dataAdapter);
}

The problem is that all of this only appears in the spinner.
