JenkinsDev / AsyncTaskHelp.java
Created November 10, 2013 20:23
Basic AsyncTask layout that I point people to when they are confused.
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.

Reverse Number Without Strings In Python
# To the not-so-mathematically-inclined, this function may look like pure witch-
# craft. That's why I shall describe how it works.
#
# Let's say we start with an initial number of `13`, we expect an output of `31`,
# right? Let's see:
#
# reverse_number(13)
#
# num = 13
# reversed_num = 0
