December 17, 2013 Leave a comment

Hi guys,

I’m going to move all my blogs and articles into my own base at,

In the new base at p’code, there will have:

  • more contents, categories and sections (Android, Image Processing, Data Mining, Data Crawling, Security…)
  • various topics related to programming.
  • better tutorials / guideline for learning stuffs.
  • re-base source code sample into my Github account.
  • (special) video tutorials in some topics for better illustration.
  • ….and many more to come.

Still, I will keep this Android Code Breaker this place for any new visitor to find the old information. However, all these old articles on this blog will be re-written for better readings, illustrations and clear code samples.

Join me and follow me at new base: P’CODE – ‘da code journal of a mindless developer.

Free 20GB Cloud Storage for everybody

July 13, 2013 1 comment

I’ve been using Copy Cloud Storage for a while, and it seems working pretty well as I expected.

However, the storage is likely to be kinda short, well, you know, cloud file storage is quite popular nowadays; and 15GB free is not enough definitely. You need to pay for more spaces.

Fortunately, Copy is running on an event for 5GB storage for each invited registration, that means you and your referred buddy will get both 5GB as bonus in your accounts. Isn’t that great?

If you are new, feel free to create account under my referral to get extra 5GB at first, and then you can invite your friends to join the cloud storage network for more spaces:

Have fun with cloud ^^~

A Note when Using Jsoup: User-Agent

January 29, 2013 1 comment

Several days ago, I’ve tried to run Jsoup on mobile testing for data parsing. My goal is to parse all questions posted on

However, the result doesn’t fit me well.

First run on simple Android code:

public class MainScreen extends Activity
    ArrayList<String> mData =  new ArrayList<String>();
    ListView mListView;
    ArrayAdapter<String> mAdapter;

    public void onCreate(Bundle savedInstanceState)

        mListView = (ListView) findViewById(;


        mAdapter = new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1,, mData);

    private void processData() {
        String URL = "";
        try {
            Document doc = Jsoup.connect(URL).get();
            Elements questions =".summary h3 a");
            for(Element question: questions) {

            if(mData.size() == 0) {
                mData.add("Empty result");

        } catch (Exception ex) {
            mData.add("Exception: " + ex.toString());

The result is empty. Well, thought of something else, so my next try is to print HTML from “doc” object, it outputs parts of full expected HTML results. So I parse with this selector: “div.nav li a”. The results show up but not for “.summary h3 a”.

After two days, working with Johnathan Hedley on GitHub, finally, found the problem is that: the mobile browser user-agent differs from the desktop browser; therefore, the HTML responses differ.

Make a note to mobile developers that use Jsoup:

+ always set a desktop user-agent

+ set a timeout

That’s good practice to avoid unexpectation.

This is the update working line:

Document doc = Jsoup.connect(URL).userAgent("Mozilla/5.0 (Macintosh; U; Intel Mac OS X; de-de) AppleWebKit/523.10.3 (KHTML, like Gecko) Version/3.0.4 Safari/523.10").get(

This issue was discussed here in GitHub:
