Install Android Studio or the Android command-line tools. Let other tools and scripts know where to find your Android SDK by setting the following environment variable: $ Step 2: Create another activity. Go to app > java > first package name > right-click > New > Activity > Empty Activity and create another activity and named it as SplashScreen. Edit the activity_splash_[HOST] file and add image, text in the splash screen as per the requirement. Here we are adding an image to the splash screen
