There’s quite a number of methods on how to approach Android Development. However, Android Studio has by far exceeded the expectations of its users. If you are looking for a platform that can help you accelerate your development and give you the leverage to build high-quality apps, then learn more about what it is.
What is Android Studio?
It is an Integrated Development Environment (IDE) that Android use to develop applications. It incorporates with the IntelliJ IDEA, a Java Integrated Development Environment when you edit codes and develop tools.
There are four components that the Studio uses to support developing in applications within the Android operating system:
- code templates
- Github integration
- Gradle-based build system
Moreover, you can utilize it with the following available OS like Linux, Mac, and Windows platform.
Android Studio Tutorial
Step 1: Set Up Android Studio
In setting up, you only have to download Android Studio and Java Development Kit.
Java Development Kit:
You only have to follow the simple instructions during the installation. Remember not to forget to tick the checkbox that includes the Android SDK.
Note: Make sure to have a large free space on your C:\ drive before you download the needed software. Choose a directory that has ample space for the Android SDK. Also, the AppData folder of Android Studio is in a hidden folder.
Step 2: Create a new project
- After Android Studio is successfully downloaded, launch the application.
- Select New Project.
- Choose the type of activity you want to perform. You can also choose to add no activity, with this you are given a blank template for you to start with.
- Click “basic activity” to have the default look for a new Android app. It has a menu and floating action button.
- Choose the activity option that perfectly fits for the app that you have in mind.
- Think of your app’s name. The package name is the name of your app along with the developer’s name. It will appear in the Google Play Store.
Step 3: Files Involved
Instead of typing and running scripts, there are various resources and files that need to be structured in a specific method.
If you wish to customize the layout of your app, you have to create it with activity_main.xml. XML files define the layout of the document.
Step 4: Connect Multiple Files
There are multiple files in a single Android app. The right portion of the main window allows you to view individual files and scripts.
There is a file hierarchy placed on the left portion of the main window. To open the Java file, double click on MainActivity.Java.
You might notice that there are two views — text view and design view. In the text view, you can add and edit lines. While in the design view, you can add, remove and drag elements. Both views have a preview window to visualize the app you are creating.
Step 5: Important Folders
“Res” is the shortcut for resources wherein drawables or images and layouts are found. You have to remember that all files in the res folder are in lower case, and each term must be separated with an underscore.
This folder contains the important variables including the colors and names of the app used.
You can find the AndroidManifest.xml in this folder. It defines the important and foundational facts of the app.
Step 6: Gradle – Build Automation Tool
Android Studio does not want its users to go through such hassle, they provide you Gradle. It is a build automation tool that assists Android Studio to convert the files into one single APK. You do not need to wait on Gradle, leave it and it will do its job. However, you can go back to build.gradle files to add a new dependency which allows advanced features for your app.
If an instance it stops working, select Build and then click on Clean Project to reaffirm the files and its roles. There will be two Gradle files, one for the whole app project and one for the module (or the app).
Step 7: Connect: Android (Smartphone) Device to Android Studio
This is the method when you will test your app in your Android device. Just follow the steps below to spring to life the app you have created with Android Studio.
Step 1: Go to Settings.
Step 2: Look for the “About Phone” menu.
Step 3: Tap the Build Number section 7 times until a prompt appears.
Step 4: Go to Developer Option.
Step 5: Enable USB Debugging.
Allow it by confirming. Tap OK.
Step 6: Install USB Driver
Download the USB Driver of your Android device from their official website. If your device uses Google USB Driver, then you can download it from the link below. You have two things to make sure of, that your device is connected through a USB cable and it is not sleeping.
Note: Update the USB Driver after it is installed. Go to Control Panel, look for Device Manager, and then right-click on the Android device and click Update Driver Software.
Step 7: Run the App
You can run the app simply through right-click and click on Run. However, you can also do this step by clicking on the Run option from the toolbar menu.
Step 8: Select Deployment Target
There will be a prompt window of Deployment Target will appear for you to select. Choose the device you would like to deploy below the Connected Device. When you have chosen a device click on OK. By then, Android Studio will run the application.
For future references, you can tick on “use the same selection for future launches”.
