You don't want to use a Thread, but an AsyncTask. Here's how:

Based on the following, figure out what you need for your app: AsyncTask

Some inspiration:

public class MyClass {
      //Something

      public MyClass() {
            new BackgroundTask().execute("Hello World");
      }
}

private class BackgroundTask extends AsyncTask {

      @Override
      protected void onPreExecute() {
            // Prepare your background task. This will be executed before doInBackground
      }

      @Override
      protected String doInBackground(String... params) {
            // Your main code goes here

            String iAmAString = "I have done something very heavy now...";
            return iAmAString;
      }      

      @Override
      protected void onPostExecute(String result) {
            // Whatever should happen after the background task has completed goes here
      }



      @Override
      protected void onProgressUpdate(Void... values) {
            // In here, you can send updates to you UI thread, for example if you're downloading a very large file.
      }
}
