Basic AsyncTask layout that I point people to when they are confused.

AsyncTaskHelp.java

public class MyAsyncTaskName extends AsyncTask<String, Integer, String> {

    // String: The first string is the parameter, this is what is passed to doInBackground()
    // Integer: The first, and only, Integer type is used for progress updates, this is what is passed to onProgressUpdate()
    // String: The second String is for what is returned by doInBackground() and what is passed to onPostExecution();

    @Override
    protected void onPreExecute() {
        // Handles what happens before the AsyncTask fully executes.
        // Here you can do things like add a progress bar, loading animation, etc.
    }

    @Override
    protected String doInBackground(String... urls) {
        // Handles the meat of the AsyncTask.
    }
    
    @Override
    protected void onProgressUpdate(Integer... progress) {
        // Handles progress updating, use this to update a progress bar, etc.
    }

    @Override
    protected void onPostExecute(String result) {
        // Handles what happens after the AsyncTask execution ends.
    }
}
