Practical No. 13

Develop a Splash Screen in Android

---

Aim

To develop an Android application that displays a Splash Screen showing
“Student Name: FirstName LastName” and automatically navigates to the main activity after a fixed delay.

---

I. Practical Significance

This practical helps students understand:

• Android Activity Lifecycle

• Timed transitions between activities

• Basic branding and first-impression UI design

Splash screens are commonly used in industry to enhance user experience during app startup.

---

II. Industry / Employer Expected Outcome(s)

After completing this practical, students will be able to:

• Implement a professional splash screen

• Use Handler.postDelayed() for timed execution

• Navigate between activities using Intent

• Configure launcher activities in AndroidManifest.xml

---

III. Course Level Learning Outcome(s)

CO3 – Develop Android applications using UI components and layouts.

---

IV. Laboratory Learning Outcome(s)

LLO 13.1 – Write a program to develop a relevant GUI for a given application.

---

V. Relevant Affective Domain Related Outcomes

• Promotes attention to user experience

• Encourages focus on first impressions in application design

---

VI. Relevant Theoretical Background

• Activity Lifecycle
  onCreate() initializes the activity; finish() removes it from the back stack.

• Handler and Delay
  Handler.postDelayed() executes code after a specified time delay.

• Intent Navigation
  Used to launch MainActivity from SplashActivity.

• UI Components
  ImageView, TextView, RelativeLayout

• Manifest Configuration
  Splash activity is defined as the launcher activity.

VIII. Program Code (Final & Corrected)

1. SplashActivity.java

package com.example.splashscreenapp;

import android.content.Intent;
import android.os.Bundle;
import android.os.Handler;

import androidx.appcompat.app.AppCompatActivity;

public class SplashActivity extends AppCompatActivity {

    private static final int SPLASH_TIME = 3000; // 3 seconds

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

        new Handler().postDelayed(new Runnable() {
            @Override
            public void run() {
                Intent intent = new Intent(SplashActivity.this, MainActivity.class);
                startActivity(intent);
                finish();
            }
        }, SPLASH_TIME);
    }
}

2. MainActivity.java

package com.example.splashscreenapp;

import android.os.Bundle;

import androidx.appcompat.app.AppCompatActivity;

public class MainActivity extends AppCompatActivity {

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

3. activity_splash.xml

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="#FFFFFF">

    <ImageView
        android:id="@+id/imgLogo"
        android:layout_width="120dp"
        android:layout_height="120dp"
        android:src="@drawable/splash_logo"
        android:layout_centerHorizontal="true"
        android:layout_marginTop="120dp" />

    <TextView
        android:id="@+id/txtStudent"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Student Name: FirstName LastName"
        android:textSize="18sp"
        android:textStyle="bold"
        android:layout_below="@id/imgLogo"
        android:layout_centerHorizontal="true"
        android:layout_marginTop="20dp" />

</RelativeLayout>

4. activity_main.xml

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:gravity="center">

    <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Welcome to Main Activity"
        android:textSize="22sp"
        android:textStyle="bold" />

</RelativeLayout>

---

5. AndroidManifest.xml

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.example.splashscreenapp">

    <application
        android:allowBackup="true"
        android:label="SplashScreenApp"
        android:theme="@style/Theme.AppCompat.Light.NoActionBar">

                <action android:name="android.intent.action.MAIN" />
                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>

    </application>

</manifest>

IX. Expected Output (Splash Screen)

Output Description:

• App launches with a splash screen

• Logo and text
  “Student Name: FirstName LastName” are displayed

• After 3 seconds, the app navigates automatically to the Main Activity

---

X. Result

Thus, a Splash Screen Android application was successfully developed using activity lifecycle methods, handler-based delay, intent navigation, and proper manifest configuration.
