Android App Development for Beginners
Steps to Build Your Own Android Application
If you are reading this tutorial, it means you are probably new to the Android app development services. Don’t worry, we will divide this tutorial into different parts to make it easy for you. The guide offers easy and useful information regarding android app development for beginners. Let’s get started by following these steps:
Before you start, there are three important things that you should know, such as:
Android OS is created using Java, so knowledge about Java is always a benefit if you want to develop an app for Android.
Then, you will need to get Android SDK, which is Android’s basic app writing program like Android Studio or Eclipse, the Java Software Development Kit (JDK). The built-in features of Android SDK provide the base needed to build some great mobile applications and providing a great opportunity for developers and entrepreneurs.
Now, you are all set to start!
Step 1: Start with Android Studio
The most common IDE for Android development is Android Studio, which comes directly from Google itself. The amazing thing about Android Studio is that it is designed specifically for Android app development services.
Step 2: Installation of Java Development Kit (JDK)
After the installation of Android Studio, it’s time for some more positive action! You also need to install Java on your machine to use Android Studio. The JDK is able to interpret and compile your code for the application development.
Step 3: Start Your Project
Choose ‘Start a new Android Studio Project’ option. Enter the name you want for your application and your ‘company domain’. All these elements will be used to create your package name in a format like:
This APK (‘Android Package File’) that you’ll in the end upload to the Google Play Store.
Step 4: Select Activity
Moreover, you’ll be given the option to pick the way you want the app to look at the beginning. This will be the look of your main ‘Activity Module’ which is basically the main page of your app. There are various fields available which you have to choose according to your app needs, such as templates, title, access to Google maps, full-screen activity, blank activity etc. As per my view, it’s better to go for ‘Basic Activity’ to keep things as simple as possible and for all intents and purposes.
Step 5: Selecting the Layout
Now, you have to choose a layout name for the selected activity. This will define that where elements like images and menus go and what fonts you’ll use. Choose a name for the menu and title as well. Pick something attractive for the title, as your users will be able to see this at some points.
Step 6: Edit the Welcome Message
Go to the activity_main.xml tab if it is not open. Click and drag the “Hello, world!” from the upper left corner of the phone display to the center of the screen. Then go to the values folder, and double-click the strings.xml file. In this file, find the line “Hello world!” and add “Welcome to my App!”
Step 7: Adding Button to your Activity
In the Palette menu to the left of display, find Button. Click and drag Button to be positioned beneath welcome message. Afterward, go to properties and find the field for text. Change the text from “New Button” to “Next Page”.
Now go back to your content_main.xml and click on the button. In the right corner, where you have your parameters for the button, you will catch an option called ‘onClick’. Click on this and then select the ‘onClick’. By doing this, you have told Android Studio that you want to associate the section of code with the button created.
Step 8: Test your App
Finally, all that’s missing to do is run the app you just made. Simple go to ‘run’ along the top and then select ‘run app’ from the drop-down menu. Follow the steps to launch the emulator running your app.
