The name might be confusing but that's historical as it started out as a simple note app. Syncing with Google Tasks was just practical and along that path it went.
If you are developing an app of your own and have any questions on how the implementation details here, don't hesitate to drop me an e-mail or something!
The app should work fine but sync will display an error message. To get it working you will need to put an API key in this file here: https://github.com/spacecowboy/NotePad/blob/master/src/com/nononsenseapps/build/Config.java
You need to replace this line:
public final static String GTASKS_API_KEY = "Put your key here";But first you will of course need to get yourself a key. Follow the instructions on this page: https://developers.google.com/google-apps/tasks/firstapp
Scroll to the section named Register your project.
Once you have put your key in the variable mention above, sync should work fine.
