Go into your Strings.xml file, and scroll to the bottom. We’re going to stash all our hints inside the XML file with all our strings, that way the java file isn’t about storage, it’s all about logic. Typos are 90% of my debugging process, so I’m a big fan of anything that means fewer lines to check. Plus it’s just giving me more chances to misplace a semicolon or use = when I mean =. That’s getting a little out of hand, right? There’s too much repetition in there. The first time that button got hit, a toast message popped up with a hint, and the second, a different one popped up. To illustrate why closets are the way to go, we’re gonna go back to the Hint button on the Riddler App from last week. You throw data inside, so that it’s easier to find and use later. To put it simply, an array is just storage space. Then we give this list as a parameter to the showDataTypes function and list it in the AlertDialog.Arrays have a beautiful way of condensing code. We give these objects as elements to the list we created in Data type. We use the data we get in the readObjects function to create objects from this model class. In this section, we have created a model class called Data. Private var progressDialog : ProgressDialog ? = null private var objectId : String ? = null private var popupInputDialogView : View ? = null private var recyclerView : RecyclerView ? = null private val TAG = 'MainActivity' override fun onCreate ( savedInstanceState : Bundle ?) Here is a preview of what we are gonna achive : Our goal is to create an Android App that can process all data types provided by Parse Server. This tutorial uses a basic app created in Android Studio 4.1.1 with buildToolsVersion=30.0.2, Compile SDK Version = 30.0.2 and targetSdkVersion 30Īt any time, you can access the complete Project via our GitHub repositories.

We recommend you NameYourClassesLikeThis (UpperCamelCase) and nameYourKeysLikeThis (lowerCamelCase), just to keep your code looking pretty. createdAt and updatedAt represent the time that each object was created and last modified in the cloud.Įach of these fields is automatically filled in by Back4app at the moment we save a new ParseObject.objectId is a unique identifier for each saved object.There are also a few fields we don’t need to specify that are provided as a convenience: For example, we could call the high score object a GameScore.

Number (primitive numeric values such as int, double)Įach ParseObject has a class name that we can use to distinguish different sorts of data.

Keys must be alphanumeric strings, and values can be: Score: 1337, playerName: 'Sean Plott', cheatMode: false
