Splash Activity in Android

In this example we are going to see how we can create splash activity or welcome activity in android.

What is Splash Screen or Activity ?


The splash screen is an activity which is launch first when you first open application.

We use splash screen just to show our app / company or our project logo or any welcome message for a couple of second.

Many of the popular android apps such as Skype, Facebook, Instagram, Twitter, Dropbox etc..., uses splash screen to display their logo. 

Most of the apps uses Android Splash Screen before launching Home Activity. 

Android splash screen is used to display a logo or brand or any welcome message for an app.

Splash Activity or Welcome Activity means we just pause our activity for few second so we use Thread class in our activity for giving pause to our activity.

Lets see example below...
