This app uses a to do list to keep track of things for you. It uses a backend service, and maintains a list across multiple platforms.
This app uses Parse (They have some of the bast documentation ever so check it out) API as a backend to store data online, such as users and objects.
Unsurprisingly the action happens in the mainActivity.java and mainActivity.xml. So open those in new tabs and look at those for a bit on your own and I'll go into more detail here.
There are some useful things to know about Parse before we get into this. If you're farmiliar with JSON, this is what parse uses to store data. JSON is just a format to store data. Here's an example.
david = {
"height" : 5.11 ,
"weight" : 180 ,
"hooves" : false
} console.log( david.height ) ;
5.11So you can store your information in this convenient format and access it really simply.
Parse uses entirely JSON objects to manage all of your data and lets you access them however you want.
Anyway, inside of here we've got some conveient things that parse takes care of for us. Parse will take care of all inserting all our data, and pulling it down when we want to use it for new activities.
