There are two options for drawables in Android Studio—the first is to inflate an image (PNG or JPGs) and the second is to define the drawing you want in an XML file. The XML route is what I’m looking at today.
Java: How to Use an Array in an App
Arrays have a beautiful way of condensing code. To put it simply, an array is just storage space. It’s a closet. You throw data inside, so that it’s easier to find and use later.
Java: How to Use an If/Else Statement
Last week we covered how toast happens in Android Studio. Today, we’re going to make it a tad more dynamic with an if/else statement. Going back to this Riddler App, I want to add hints for the user if they can’t guess the answer outright. Quick reminder, our test riddle was “What has a neck but no head?” Most people start guessing insects for that one (isn’t an earthworm basically all neck? you might argue), but the answer we’re looking for is “A Bottle.”
To keep the mystery alive, we’re going to keep hints semi-living creatures related. If a user hits the Hint button once, a toast message will pop out reading, “It has no fingers or toes either.” Otherwise, the toast will say, “And lives all over the world.”

Java: How to Add Toast to an App
Today’s tutorial is a continuation of How to Make a Genuinely Basic App. All we’re doing is adding a method to give a new button a job. This is the coding equivalent to dipping a toe in the water so as to not become overwhelmed at the sheer horror of all the java inside a basic project in Android Studio.
The method of choice for our experiment—toast.
Java: How to Make a Genuinely Basic App
I’m back! After a short 14 month siesta, I’ve decided to change gears and pick up App design.
Don’t worry. Today’s tutorial is going to be extremely light on the coding because for the most part, we’re just generating a hoard of files with pre-written code. After that, this is going to be an exercise in strategically ignoring all but the most essential bits required to make an Android app. Our goal is to adapt a few key pieces of that code to lay the groundwork for java tutorials in the future.
Let’s get started.
