As the app starts, you’ll see the default splash screen: the app logo centered on a screen colored to match windowBackground from your app theme. Build and run the app, force close and reopen from the launcher. In Android Studio, change your target emulator to API 31.
Improving users’ experience and reducing the feeling of delay is one of the reasons developers added their splash screen implementation. A blank screen shows when the app starts. That ensures the app opens from a cold start - more on that later.Īndroid 10 doesn’t have a default splash implementation. To force close, swipe up on the app from the Recents section of the device. Each time you run the code in this tutorial, you should force close the app and reopen it from the launcher. For most development tasks, that isn’t a problem, but the launch method is critical when testing the splash screen. Note: Running the app through Android Studio is not the same as launching the app from the system launcher. Don’t worry, you don’t need to buy a second phone! Instead, set up two emulators, each running a different API version. To comprehend the changes, run the sample project across two versions of Android to see each version’s behavior. Regardless of whether you choose to use and implement the SplashScreen API, the default behavior changed with Android 12. For this sample project, the minSdkVersion is set to 29 (Android 10). Luckily, the AndroidX SplashScreen compat library supports backward compatibility. You want to enable as many users as possible. You should base this on the number of users running each Android version in your target demographic. However, even if you start a project from scratch, it is always recommended to provide back support for a few previous versions when picking your app’s minimum SDK version. The targetSdkVersion must be set to at least 31 in adle. Choosing the Target SDK VersionĪndroid 12 introduced the SplashScreen API.
If you’re not interested in migrating an old implementation of a splash screen, ignore the TODO comments labeled: // TODO: (Legacy Migration) and the file LegacySplashActivity.kt. This tutorial covers adding your first splash screen and migrating a legacy implementation. The app – ColorSplash contains one screen showcasing Material Design-recommended color palettes. Open the project in Android Studio Bumblebee or later and get familiar with the files.
