Splash Screen Tutorial for Android

Fast forward to Android 12, which added the SplashScreen API. From Android 12 onward, all apps show a default splash screen, and developers can customize it according to their requirements.

Creating a Simple Splash Screen

1. Adding the Dependency

■ SplashScreen API Dependency

build.gradle

implementation 'androidx.core:core-splashscreen:1.0.0-beta01'

2. Adding the Adaptive Icon

■ SplashScreen API theme

styles.xml

<style name="Theme.App.Starting" parent="Theme.SplashScreen">
  <item name="windowSplashScreenAnimatedIcon">@drawable/ic_launcher_foreground</item>
  <item name="postSplashScreenTheme">@style/AppTheme</item>
  <item name="windowSplashScreenBackground">@color/ic_launcher_background</item>
</style>

■ Legacy Splash Screen Theme

  <style name="LegacySplashTheme" parent="Theme.AppCompat.NoActionBar">
    <item name="android:windowBackground">@drawable/legacy_splash_background</item>
    <item name="android:windowTranslucentStatus">true</item>
    <item name="android:windowTranslucentNavigation">true</item>
  </style>

3. Setting the Style

■ SplashScreen API Setting

android:theme="@style/Theme.App.Starting"

Your file should look like this:

        <activity
            android:name=".MainActivity"
            android:exported="true"
            android:theme="@style/Theme.App.Starting">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />
                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>

■ Legacy Splash Screen Setting

   <activity
      android:name=".LegacySplashActivity"
      android:theme="@style/LegacySplashTheme"
      android:exported="true">
      <!--
        launching Activity. Note: You will also need to comment out the equivalent intent-filter
        block of the MainActivity above.
      -->
      <intent-filter>
        <action android:name="android.intent.action.MAIN" />
        <category android:name="android.intent.category.LAUNCHER" />
      </intent-filter>
    </activity>

4. Installing the Splash Screen

■ Installing SplashScreen API

MainActivity.kt

import androidx.core.splashscreen.SplashScreen.Companion.installSplashScreen

val splashScreen = installSplashScreen()

Your file should look like this:

  override fun onCreate(savedInstanceState: Bundle?) {

    // TODO: Install Splash Screen
    val splashScreen = installSplashScreen()

    super.onCreate(savedInstanceState)
    setContentView(R.layout.activity_main)

    startLoadingContent()
