The splash screen is a launcher activity of an application that is visible for users only for 1 or 2 seconds.
To create a splash screen you just need to follow a few steps...
step 1: open android studio and create a project with an empty activity. eg: mainActivity.java
step 2: Now you need to create a second activity and set this activity as a launcher activity while you create a new activity. eg: splashScreen.java You can also change this setting from your manifest file.
step 3: Design your XML file. This is for how your splash screen looks like.
step 5: Now go to the splashScreen java file and you need to write a few codes to connect your splashScreen activity to mainActivity.
Your splash screen is ready to launch 👍
