Splash Screen API in Android 12 | Android 12 Splash Screen Example | Splash screens in Android 12 | Splash screen demo Using Splash Screen API | Splash Screen API Example

 Hi All,

         Today I am going to share a tutotial and a sample demo of Android 12 

Splash Screen Api.  Android 12 Splash screen api introduce in Android 12.

Android 12 adds the SplashScreen API, which enables a new app launch animation

for all apps when running on a device with Android 12 or higher. This includes an

into-app motion at launch, a splash screen showing your app icon, and a transition

to your app itself. 

Note: As Splash Screen  introduced in Android 12 so it will work on Android 

Api level 31 and above. 

We can Customize the Splash Screen Theme:

                - With the help of below attribute we can customize our Splash activity theme.

1. android:windowSplashScreenBackground : Used for Splash Screen background color.

#FFFFFF	

2. android:windowSplashScreenAnimatedIcon:  Used to replace an icon in

the center of the starting window. If the object is animatable and drawable through AnimationDrawable and AnimatedVectorDrawable, you also need to set windowSplashScreenAnimationDuration to play the animation while showing the

starting window.

	@drawable/splash_screen_animateable_icon
	

3. android:windowSplashScreenAnimationDuration : Used to indicate the duration of the splash screen icon animation. Max duration is 1000ms.

800	

4. android:windowSplashScreenIconBackgroundColor : Used to set a background behind

 the splash screen icon. This is useful if there isn’t enough contrast between the window

 background and the icon.

#004d28	

5. android:windowSplashScreenBrandingImage: We can use this to set an image to be shown at the bottom of the splash screen. The design guidelines recommend against using a branding image.

Keep the splash screen on-screen for longer periods:

The splash screen is dismissed as soon as your app draws its first frame. If you need to load a small amount of data such as in-app settings from a local disk asynchronously, you can use ViewTreeObserver.OnPreDrawListener to suspend the app to draw its first frame.

If your starting activity finishes before drawing (for example, by not setting the content view and finishing before onResume), the pre-draw listener is not needed.

override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setContentView(R.layout.activity_main)
        mainViewModel = ViewModelProvider(this).get(MainViewModel::class.java)
        content = findViewById(android.R.id.content)
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.S) {
            Log.d("MainActivity", "onCreate: I AM RUNNING ON API 12 or higher")
            content.viewTreeObserver.addOnPreDrawListener(object :
                    ViewTreeObserver.OnPreDrawListener {
                    override fun onPreDraw(): Boolean =
                        when {
                            mainViewModel.mockDataLoading() -> {
                                content.viewTreeObserver.removeOnPreDrawListener(this)
                                true
                            }
                            else -> false
                        }
                })
        }
    }	

Customizing Splash Screen Animation: In Android 12 we get the Splash screen 

instance by calling getSplashScreen() from Activity class. So we can further customize

the animation of the splash screen through Activity.getSplashScreen().

        splashScreen.setOnExitAnimationListener { splashScreenView ->
            val slideUp = ObjectAnimator.ofFloat(
                splashScreenView,
                View.TRANSLATION_Y,
                0f,
                -splashScreenView.height.toFloat()
            )
            slideUp.interpolator = AnticipateInterpolator()
            slideUp.duration = 200L

            // Call SplashScreenView.remove at the end of your custom animation.
            slideUp.doOnEnd { splashScreenView.remove() }

            // Run your animation.
            slideUp.start()
        }
