Prerequisites for android app development:

Before creating the Android app, it is essential to have basic knowledge of Kotlin. Developers are required to have the latest version of Android Studio to create the Android app. Get in touch with Bosc Tech Labs for professional Android app development services.

Kotlin is one of the preferred languages for developing Android apps. It is important to choose Kotlin as the language and change the app name accordingly.

Steps to create the first android app with android studio:

Step 1: Create a new project

Use the Android Studio for the project to design, develop and even build the Android app. You can simply launch the Android Studio by clicking the “Start” button for the Android Studio project. Follow the steps below to create the new project.

  • Go to http://developer.android.com/sdk/index.html
  • Download Android Studio
  • Install and open Android Studio
  • Choose the “Quick Start” menu
  • Click “Start a new Android Studio project.”
  • Open the “Create New Project” window
  • Name project “GORT”
  • Check the location of the project file and make necessary changes to it if desired.
  • Hit “Next”
  • Click the ‘Phone and Tablet’ box

Test the app on the phone and ensure the minimum SDK is set below the phone’s operating system level.

  • Enter “Next”
  • Choose “Blank Activity”
  • Enter “Next”
  • Leave all Activity name fields as they are.
  • Enter “Finish”

Using the updated version of the Android Studio lets you easily get your app running on many numbers of devices. These also require minimum API-level support. 

Whether you are looking to set your unique theme or template, then you can choose ‘Add No Activity’ from Android Studio. You will be able to access the form to enter the details about the apps. These include the Name, package name and many more. 

Set the names of users before seeing the phone when installing the app. The package name is the unique identifier for the app in Google Play, and you can follow the Java package naming to specify it.

Step 2: Create a main activity:

Activity is an important component in the Android app, which easily allows for the creation and displaying of the User Interface. These are suitable for the user to easily get access to more activities. Each of them allows the user to perform the action easily. 

For instance, whether you are developing an email client app, it is essential to have major activities such as the user signing up, composing an email, and other activities for the user signing in. Follow the steps below to create the main activity.

  • Open activity_main.xml tab
  • Open Design tab on the activity_main.xml display
  • Click and drag the “GORT” to the tab
  • Open the values folder in the project file system on the left side of the window
  • Double-click the strings.xml file in the values folder
  • Find line “GORT” in file
  • Add “Welcome to my app!” after “GORT” message
  • Navigate to activity_main.xml tab
  • Check whether the centred text reads as” GORT! Welcome to my app!”

Step 3: Adding button on main activity:

Upon getting the welcome message for your app, it is essential to add the button on the main activity. Follow the instructions below to add the button to the main activity.

  • Open activity_main.xml display and click the ‘Design’ tab
  • Find “Button” (seen under the heading Widgets)
  • Open the Palette menu on the phone display
  • Click and drag “Button” to centred underneath the welcome message
  • Make sure the button is still selected
  • Scroll to find “text”
  • Add “Next Page”
  • Navigate to New
  • Click Activity
  • Click Blank Activity
  • Change the Name of this activity to “SecondActivity.”
  • Click “Finish.”

Step 4: Create a layout:

Normally, all the Activities involve a minimum of a single layout associated with them. Upon creating the activity in the previous step, you need to generate the empty layouts. 

Open the activity_main.xml file to simply view the list of activities. Add the activity’s layout with Views and view groups. The View is sometimes referred to as the widget in the app. These are set with individual components on the user interface. 

Adding the Buttons, labels, and text fields are some of the common examples in Views. View Group is the component that serves as a container for views. View groups help to set the position and dimensions of views.

Button button = (Button) findViewById(R.id.button);
button.setOnClickListener(new View.onClickListener() {
@Override
public void onClick(View v) {
goToSecondActivity();
}
});
private void goToSecondActivity() {
Intent intent = new Intent(this, SecondActivity.class);
startActivity(intent);
}

Step 5: Test the application and launch:

Testing the application before launching it is essential to ensure it runs smoothly on all devices. Follow the steps below to test the application easily.

  • Click the green play symbol from the toolbar in the Android Studio window
  • Click “Choose Device” dialog appears
  • Click the “Launch emulator” option
  • Enter “OK.”
  • Emulator opens
  • The app automatically launches the app on a virtual phone
  • Make sure all text displays correctly
  • Make sure the button takes you to the next page

Conclusion:

You have completed the first Android application using simple techniques. Upon opening the app, the application greets the user, and the button takes the user to the second page. The app will be a fully functional app for Android, and you can make changes based on your requirements.
