How to implement a after effect project/video as splashscreen?

I have created a After effects animation of 5 sec and of resolution 1080x1920. I want to play that video(AE project) as splashscreen. I've just tried it with a full screen activity and using videoview but it's lagging. I also tried to use lottie master but without instructions, I failed miserably. So if you guys have a better way to do so and have no problem in sharing, please help.
