I updated the code as following. However, now I see that the display

Log.d(TAG, OnCreate begins);
super.onCreate(savedInstanceState);
setContentView(R.layout.notes_fetch);
new HttpConnect1().execute();

{
try {
URL connectURL = new URL(linkUrl);
HttpURLConnection conn = (HttpURLConnection)

byte[] data = new byte[1024];
int len = dis.read(data, 0, 1024);

Never do HTTP I/O on the UI thread. Use AsyncTask or something to do

It is impossible to tell. Use a debugger, or put some Log calls in
onPostExecute(), and confirm that it is being called. Or, check your
LogCat to see if you are getting an exception that is being logged by
your existing code.

I am acquiring a wakelock as the error points to giving up a wake

Maybe it's trying to access an external website during the processing
