How to Create an Android Studio Application for Beginners
In this video tutorial, we’ll be showing you how to create a basic Android Studio application for absolute beginners in Android development. Follow the step-by-step instructions below to create your own app:
Step 1: Create a New Android Studio Project
To get started, create a new Android Studio project. Next, select the activity for your application. You can choose from any of the available activities, but for this tutorial, we’ll be using an empty activity.
Step 2: Give Your App a Name and Package Name
Now, give your application a name and change the package name to the location where you want to save your project. You can select the programming language that you would like to use. For this tutorial, we’ll be using Java.
Step 3: Select the Minimum Android Version Required by Your App
The minimum SDK means the minimum version of Android required by your application. Select the version that you would like to use. For this tutorial, we’ve selected KitKat. Please note that if you select a higher version of Android, users with lower versions will not be able to use your application.
Step 4: Wait for Your Project to Build
Now, wait for your project to be completely built. Once it’s done, you’ll see a folder called Java. Inside this folder, you’ll keep all your Java programs, and you’ll only be using the folder called comm. first app. app. This is the package name we gave earlier, and you won’t need the other two folders that are automatically generated.
Step 5: Add a New Java File
To add a new Java file, right-click on the folder and click “new” and “Java”. Give the file a name and click “OK”.
Step 6: Design Your App in the Layout File
Next, go to the resources folder and inside the layout folder, you’ll see your layout files. Here, you’ll do all the designing part of your application. You’ll keep all your images and other resources inside the drawable folder.
Step 7: Add an Image to Your Layout
Now, let’s add an image to your layout. Copy the image and paste it inside the drawable folder. Do not select any folder other than the drawable folder. Make sure your file name does not contain any capital letters, and always use small letters in naming your file.
Step 8: Insert an Image View
Next, select the palette common and image view. If the palette is minimized, click the palette to display it. Drag and drop the image view, select the image, and click “OK”. The image might appear too large, so go to the attributes and adjust the layout width to match parent and layout height to 300 DP.
Step 9: Add Constraints to Your Layout
Now, we must add constraints to your layout by clicking the plus symbols. This will automatically set the constraints and place the image view properly in position. If you want to modify the text, you can also change it in the attribute side.
Step 10: Customize Your App with XML Code
If you would like to edit the codes, select the edit with preview option, and you’ll be able to see the XML code of your layout. You can customize your text by specifying the text size and text type according to your preference. Split your screen to view the preview mode.
Step 11: Run Your App on an Emulator
To run your application, select the emulator, or if you don’t have one created, open the AVD manager and create a new virtual device. Select the device you want to create, choose the Android version, and give a name to the emulator. Click finish, and the emulator will be created. Select your device and click the play button, and your application will be installed and launched automatically on the emulator.
