Creating a Fullscreen Activity in Android

Creating a fullscreen activity in Android is a common requirement for many applications, whether it’s to provide an immersive experience for gaming, video playback, or other media-rich applications. This guide will walk you through the steps to achieve a fullscreen activity, hiding the notification bar and other system UI elements.

Method 1: Programmatically Setting Fullscreen Mode

You can programmatically set your activity to fullscreen mode by using the following code:

public class ActivityName extends Activity {
    public void onCreate(Bundle savedInstanceState) {
        // Remove title

Method 2: Using AndroidManifest.xml

Alternatively, you can set your activity to fullscreen mode by modifying your AndroidManifest.xml file:

<activity android:name=".ActivityName"

Method 3: AppCompatActivity with Custom Theme

If you are using AppCompatActivity, you will need to define a custom theme:

<style name="Theme.AppCompat.Light.NoActionBar.FullScreen" parent="@style/Theme.AppCompat.Light.NoActionBar">
    <item name="android:windowNoTitle">true</item>
    <item name="android:windowActionBar">false</item>
    <item name="android:windowFullscreen">true</item>
    <item name="android:windowContentOverlay">@null</item>

Then apply this theme to your activity in AndroidManifest.xml:

<activity android:name=".ActivityName"

Additional Considerations

For applications targeting Android KitKat and above, you can leverage the Immersive Full-Screen Mode. This mode provides a more interactive fullscreen experience, especially useful for gaming applications.
