This is also called splash screen.

Here an example of how you can implement a splash screen in Android:

1. Create a new layout file for your splash screen. For instance, you can create a file named `activity_splash.xml` in your `res/layout` directory. Customize the layout according to your design requirements.

“`xml
<!– activity_splash.xml –>
<LinearLayout xmlns:android=”http://schemas.android.com/apk/res/android”
android:layout_width=”match_parent”
android:layout_height=”match_parent”
android:orientation=”vertical”
android:gravity=”center”
android:background=”@color/splash_background”>

<!– Add your splash screen content here –>
<ImageView
android:layout_width=”wrap_content”
android:layout_height=”wrap_content”
android:src=”@drawable/splash_logo”
android:contentDescription=”@string/splash_logo_description” />

<TextView
android:layout_width=”wrap_content”
android:layout_height=”wrap_content”
android:text=”@string/app_name”
android:textColor=”@color/white”
android:textSize=”24sp”
android:paddingTop=”16dp” />

</LinearLayout>
“`

2. Create a new activity class for the splash screen. For example, you can create a file named `SplashActivity.java`. In this activity, set the desired layout using `setContentView()` in the `onCreate()` method and apply any additional logic or customization.

“`java
public class SplashActivity extends AppCompatActivity {

private static final long SPLASH_DELAY = 2000; // 2 seconds

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_splash);

// Delay for a specific time and then launch the main activity
new Handler().postDelayed(new Runnable() {
@Override
public void run() {
Intent intent = new Intent(SplashActivity.this, MainActivity.class);
startActivity(intent);
finish();
}
}, SPLASH_DELAY);
}
}
“`

In the above code, we set the content view to the `activity_splash.xml` layout. Then, using a `Handler` and `postDelayed()`, we create a delay of 2 seconds (you can adjust this value as needed) before starting the `MainActivity`.

3. Declare the SplashActivity in your AndroidManifest.xml file by adding the following code within the `<application>` element:

“`xml
<activity
android:name=”.SplashActivity”
android:theme=”@style/Theme.Splash”
android:exported=”true”>
<intent-filter>
<action android:name=”android.intent.action.MAIN” />
<category android:name=”android.intent.category.LAUNCHER” />
</intent-filter>
</activity>
“`

Ensure that the `android:name` attribute points to the correct package name and class name for your SplashActivity.

4. Optionally, you can define a custom theme for your splash screen in your `styles.xml` file:

“`xml
<style name=”Theme.Splash” parent=”Theme.AppCompat.NoActionBar”>
<item name=”android:windowBackground”>@drawable/splash_background</item>
</style>
“`

In this example, we set a custom window background for the splash screen using the `splash_background` drawable resource.

Remember to replace `@color/splash_background`, `@drawable/splash_logo`, and `@string/app_name` with your own color, drawable, and string resources, respectively.

With these steps, you can implemented a basic splash screen in your Android application. The splash screen will be displayed for the specified duration and then transition to your main activity (`MainActivity` in this example).

In Android development, a bundle is a container that holds data as key-value pairs. It is primarily used for passing data between components, such as activities, fragments, and services. Bundles are often utilized when you want to send data from one screen to another or when you need to preserve data during configuration changes, such as device rotation.

Here are some common use cases for bundles in Android development:

Passing data between activities,Fragment communication,Saving instance state,nter-process communication.

To create a bundle, you can use the ”Bundle” class provided by the Android framework. It offers methods to store various types of data, such as strings, integers, booleans, and Parcelable objects.

Overall, bundles are a versatile tool in Android development that facilitate the transfer and preservation of data between components, making it easier to build interactive and dynamic applications.
