Creating a New Android Project

To create a new Android project, open Android Studio and click on the "New Project" button. Select the "Empty Activity" template and click on the "Next" button.

Enter a name for your application and click on the "Finish" button. Android Studio will create a new project and open the main activity file.

The Main Activity

The main activity is the starting point of your application. It is responsible for creating the user interface and handling user input.

The main activity is defined in the file. The following code shows the main activity:```java
package ;
import ;
import ;
import ;
public class MainActivity extends Activity {
@Override
protected void onCreate(Bundle savedInstanceState) {
(savedInstanceState);
setContentView(.activity_main);
TextView textView = (TextView) findViewById();
("Hello, world!");
}
}
```

In this code, the setContentView() method sets the user interface of the activity to the file. The findViewById() method is used to find the TextView widget in the user interface and set its text to "Hello, world!"

Running the Application

To run the application, click on the "Run" button in the Android Studio toolbar. The application will be installed on your device or emulator and launched.
