This blog is about get current version of Android app on Play Store android using Jsoup. There is no official API to get version number but we can get it by reading HTML.  

Here we start.

1. Create Project.

2. Open Manifest file and add Internet permission.

<uses-permission android:name="android.permission.INTERNET"></uses-permission>

3. Open Gradle file and add below line to compile Jsoup library.

 compile 'org.jsoup:jsoup:1.9.2'

4. Open Activity class.

5. Create new Thread.

6. Create Document object.

 Document doc = null;

7. Initialize with Jsoup.connect.

 doc = Jsoup.connect("YUOR_APPLICATION_URL").get();

8. Get Elements which use css class '.meta-info .content' :-

Elements cssElements = doc.select(".meta-info .content");

9. Get Single element from position 4th.

Element ele = cssElements.get(3);

10. You will get <DIV> of app version. Now you can get <div> value to get Version number.

 Elements text = ele.select("div");
                    String versionNumber = text.text();

11. Full Stack Code.

new Thread(new Runnable() {
            @Override
            public void run() {
                Document doc = null;
                try {
                    doc = Jsoup.connect("TYPE_APP_URL_HERE").get();
                    Elements cssElements = doc.select(".meta-info .content");
                    Element ele = cssElements.get(3);

                    Elements text = ele.select("div");
                    String versionNumber = text.text();

                    Log.i("App version:- ",versionNumber);
                } catch (IOException e) {
                    e.printStackTrace();
                }
            }
        }).start();

Happy coding :D
