Loading Images,Videos in background

Issue

I am trying to make an App which is going to display Some Images and Videos. So I am planning to add a splash screen of around 2seconds. After 2 seconds the user will be taken to the Main Screen of the App.

I want to start the loading of the Images, Video when then user is at the splash screen itself so that the user should wait for the least time when he is at the Main Screen.

So the loading will be started at the Splash Screen and then after two second the user will be taken to main screen irrespective of the completion of the loading. Now since this involves two activities should I use a Async task or should I Use a service with an Async Task(For the callback of completion of code) within it?

Which one would be better. Also in Android 8.0 are there any restriction in using Services?

I think using a Async Task between two screens may cause Memory leak if not coded properly.

Any help would be really grateful.

EDIT: My app is having one more feature hence cannot make the user wait in the Splash Screen till the loading is over.

Solution

It is not very good to use AsyncTask for sharing results between 2 activities, because AsyncTack created in Splash activity will be destoyed (stopped) when switched to Main activity. Better to use service in this case and Main screen will subscribe for result.
