Implementing a Splash Screen, the wiser way
What is a Splash Screen?
A Splash Screen is basically a nice intro-screen that mobile applications have on startup of the app on a device. The splash screen can be customized according to the app’s UX need-animations, sound effects, etc. are some common tweaks to a simple splash screen.
Neurolab Splash Screen
While developing this, we followed Google Material Design guidelines and the pattern it suggests is termed as ‘Launch Screen’. Displaying a launch screen can decrease the sense of long load time, and has the potential to add delight to the user experience. Launch screen implementation is considered as one of the best-practised development skills for a proper splash screen for an app.
Now, it is not a good idea to use a splash screen that wastes a user’s time. This should be strictly avoided. The right way of implementing a splash screen is a little different. In the new approach specify your splash screen’s background as the activity’s theme background. This way, we can effectively and efficiently use the time gap between the startup of the app and the onCreate() method.
In the Neurolab app, we use the splash screen as a bridge for the time gap between the app startup when we click the app icon and the onCreate method of the Neurolab Activity (Main/Launcher Screen) of the app, wherein the various UI components are laid out on the screen and the functionalities, navigations, listeners are linked to those components.
So, here we won’t be creating a new layout for the Splash screen as a separate activity. Rather we would specify the theme of the landing activity as the splash screen.
We create a drawable named splash_screen.xml in our project and give a parent tag of layer-list. Here is the code for our drawable file:
Next, we are going to create a new theme in the styles resource file. This theme is going to be used as the base theme for the main activity screen of the app. In this style, we specify our created drawable file to the property name windowBackground.
Then, update this style in the project manifest file to set the theme of the main activity
Having done the steps so far, we create a simple class extending the AppCompatActivity. Note- This may seem like another Activity screen, but it is not. We don’t specify the setContentView() here. Instead of this class just directs to the main/home activity using an Intent. Finally, be sure to finish() the SplashActivity activity (class) to remove prevailing unused/idle activities from back stack.
We are done!!
Launch your app, and observe your Launch screen. I can promise you that your “time won’t be wasted”(pun intended).
Thanks for reading. Hope this adds value to your Android application development skills.
