Answer 1

I can't just make your code an AsyncTask but I can give you an example and some help. This is an example of AsyncTask

public class TalkToServer extends AsyncTask {
@Override
protected void onPreExecute() {
    super.onPreExecute();
}

@Override
protected void onProgressUpdate(String... values) {
    super.onProgressUpdate(values);

}

@Override
protected String doInBackground(String... params) {
//do your work here
    return something;
}

@Override
protected void onPostExecute(String result) {
    super.onPostExecute(result);
       // do something with data here-display it or send to mainactivity

}

All of your network stuff you will put in doInBackground() then if you need to update the UI you did that in the other methods. After finishing the network stuff you can update UI in onPostExecute().

This is how you would call the task

TalkToServer myAsync = new TalkToServer() //can add params if you have a constructor
myAsync.execute() //can pass params here for `doInBackground()` method

If it is an inner class of your MainActivity then it will have access to member variables of MainActivity. If its a separate class then you can pass context to constructor like

TalkToServer myAsync = new TalkToServer(this);

and create a constructor to accept Context and any other params you want

I strongly suggest going through the docs below and make sure you understand how it works. Maybe the biggest thing to understand when getting started is that doInBackground() doesn't run on the UI so you don't want to try and update any Views here but in the other AsyncTask methods or by passing data back to the MainActivity and update there AsyncTask
