Android - วิธีการเช็ค version app ของเราผ่าน GooglePlay ไหมครับ??

public class VersionChecker extends AsyncTask<String, String, String>{

String newVersion;

@Override
protected String doInBackground(String... params) {

    try {
        newVersion = Jsoup.connect("https://play.google.com/store/apps/details?id=" + "package name" + "&hl=en")
                .timeout(30000)
                .userAgent("Mozilla/5.0 (Windows; U; WindowsNT 5.1; en-US; rv1.8.1.6) Gecko/20070725 Firefox/2.0.0.6")
                .referrer("http://www.google.com")
                .get()
                .select("div.hAyfc:nth-child(4) > span:nth-child(2) > div:nth-child(1) > span:nth-child(1)")
                .first()
                .ownText();
    } catch (IOException e) {
        e.printStackTrace();
    }

    return newVersion;
}

VersionChecker versionChecker = new VersionChecker();
    String latestVersion = versionChecker.execute().get();
