To get to know how you can create Apps for your devices, Appinventor is a must. Students at 4th ESO start to create Apps and verify them with their own mobiles,
MIT! App Inventor allows you to create mobile applications for Android devices using blocks as a coding language. In this lesson, we'll cover the basics of using App Inventor to create a simple app.
To get started with App Inventor, you'll need to have an Android device and a Google Account. You'll also need to install App Inventor Companion app on your Android device.
Once you've set them up, you can visit App Inventor's (ai2.appinventor.mit.edu) website to start building your app.
The first thing you will see when you open App Inventor is the “Designer” view. This is where you can craft your app's UI design by adding buttons, tags, and other UI elements.
To add an item to your app, simply drag it from the palette on the right side of the screen and drop it into the “Viewer” in the center of the screen.
Next, we will move on to the “Blocks” view. This is where you'll add the code that determines how your app will behave. To do this, you will use blocks that represent different actions or data. For example, you can use a “Button.Click” block to specify what should happen when the user clicks on a button in your app.
To start creating the logic of your application, you will need to create a “Procedure” by dragging a block “Define procedure” from the palette “Control” and give it a name. You can then add blocks within the procedure to specify what actions should be taken when the procedure is called.
For example, you can create a procedure called “OnButtonClick” that displays a message when the user clicks on a button in your app. To do this, drag a blog “Button.Click” and a blog “Show alert” to the procedure “OnButtonClick” and connect them like this:
Button. Click → Show alert.
This instructs App Inventor to display an alert message when the button is clicked. You can customize the message by clicking on the “Show alert” block and entering the text you want to display.
Now that you have the basics, you can start creating your own app with App Inventor! Remember to use the “Designer” view to design your app's design and the “Blocks” view to add the code that determines how your app will behave. With a little practice and creativity, you'll be creating amazing apps in no time!
You’ll program animations, interactive art, and games in Game Lab. Start off with simple shapes and build up to more sophisticated sprite-based animations and games, using the same programming concepts and the design process computer scientists use daily. In the final project, you’ll develop a personalized, interactive program.
