Android Studio Lollipop

Android Studio Lollipop is a version of the Android Studio IDE that was released in November 2014. It provides developers with tools to build Android apps that are optimized for the Lollipop operating system.

Syntax

Android Studio Lollipop uses the Java programming language and the Android SDK to build apps. The syntax for Android app development includes:

• XML layout files to define the user interface
• Java classes for the app logic
• Android manifest files for the app configuration

Example

Here is an example of a simple Android app that displays a "Hello, world!" message:

public class MainActivity extends AppCompatActivity {
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        TextView textView = (TextView) findViewById(R.id.textView);
        textView.setText("Hello, world!");
    }
}

Output

When the app is run, it displays a message that says "Hello, world!" on the device's screen.

Explanation

This example demonstrates how to create a new activity and set its layout to display a message in a TextView.

• The onCreate method is called when the activity is created.
• The setContentView method sets the activity's layout to the activity_main layout file.
• The TextView object is retrieved from the layout using its ID.
• The setText method sets the text of the TextView to "Hello, world!".
