The which i am using to parse is this.

public void ParsingCall(final String urlFirst) {
    final Bundle b = new Bundle();
    progressDialog = ProgressDialog.show(SearchResults.this, " ",
            "Searching.....", true, false);
    progressDialog.setIcon(-1);

    progressDialog.setIcon(R.drawable.logo);
    new Thread(new Runnable() {

        public void run() {
            LyricsData dataContent = null;

            dataContent = LyricsParse.Parse(urlFirst);
            Message msg = new Message();
            {

                {
                    if(dataContent.contentList != null) {
                        b.putStringArrayList("contentList",
                            dataContent.contentList);
                    }else {
                        //dataContent.contentList[0] = {"No value"};
                        b.putString("contentList",
                                "No value");
                    }
                    if(dataContent.optionNameArrayList != null)
                    b.putStringArrayList("optionNameArrayList",
                            dataContent.optionNameArrayList);
                    else
                        b.putString("optionNameArrayList",
                                "No value");
                }
            }

            msg.setData(b);

            handler.sendMessage(msg);

        }
    }).start();
}

I have also written an handler which will get the message and from that getting data and setting those to the view i am having in the activity. Please note that this exception is not getting every time. It is getting very rarely.

There is error in your run method.Place debug point at starting of run method and you will a variable which is being initialized to NULL.

You are getting a NullPointerException at line 147 of your SearchResults.java file as per this line:

10-16 12:46:59.783: E/WindowManager(4362):  at com.android.gyan.SearchResults.ParsingCall(SearchResults.java:147)

Please make sure that all the variables on this line are initialized and are not set to null. I'm guessing you are calling ProgressDialog.show() but you haven't initialized your ProgressDialog variable or your initialization is out of scope.
