Answer 1

You need to put it into AysncTask

 //********* Check for Updated Version of APP
    private class GetVersionCode extends AsyncTask<Void, String, String> {
        String currentVersion = null;

        @Override
        protected String doInBackground(Void... voids) {

            String newVersion = null;

            try {
                currentVersion = getPackageManager().getPackageInfo(getPackageName(), 0).versionName;
                newVersion = Jsoup.connect("https://play.google.com/store/apps/details?id=" + Activity.this.getPackageName() + "&hl=it")
                        .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[itemprop=softwareVersion]")
                        .first()
                        .ownText();
                return newVersion;
            } catch (Exception e) {
                e.printStackTrace();
            }
            return null;
        }

        @Override
        protected void onPostExecute(String onlineVersion) {
            super.onPostExecute(onlineVersion);
            if (onlineVersion != null && !onlineVersion.isEmpty()) {
                if (!currentVersion.equalsIgnoreCase(onlineVersion)) {
                    //Todo code here

                }
            }
            Log.d("update", "Current version " + currentVersion + "playstore version " + onlineVersion);
        }
    }

Answer 2

The problem arises because the element div [itemprop = softwareVersion] is no longer found on the Google Play website (therefore it no longer returns the version number), it should only be changed to a new query with the changes made by google on your website.

Note: Take into account that if the structure is changed again, this code must be changed.

I hope it helps

Update: 12/09/2019

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

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

        private String newVersion;

        try {
        Document document = Jsoup.connect("https://play.google.com/store/apps/details?id=" + "com.example.package" + "&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();
        if (document != null) {
            Elements element = document.getElementsContainingOwnText("Current Version");
            for (Element ele : element) {
                if (ele.siblingElements() != null) {
                    Elements sibElemets = ele.siblingElements();
                    for (Element sibElemet : sibElemets) {
                        newVersion = sibElemet.text();
                    }
                }
            }
        }
        return newVersion;
    }
}

Codigo Java

VersionChecker versionChecker = new VersionChecker();
try {
    String latestVersion = versionChecker.execute().get();
    String versionName = BuildConfig.VERSION_NAME.replace("-DEBUG","");
    if (latestVersion != null && !latestVersion.isEmpty()) {
        if (!latestVersion.equals(versionName)) {
            showDialogToSendToPlayStore();
        }else{
            continueWithTheLogin();
        }
    }
    Log.d("update", "Current version " + Float.valueOf(versionName) + ", Playstore version " + Float.valueOf(latestVersion));

} catch (InterruptedException e) {
    e.printStackTrace();
} catch (ExecutionException e) {
    e.printStackTrace();
}
