Android - Unity Pro to Basic migration, Splash Screen error

I have migrated my project from Unity Pro to Unity Basic. Earlier the project happens to have a 'non-default/custom/non-unity' Splace Screen. However when I have migrated to Basic one, on building and running the project for iOS in Xcode, I recieved an error message as

"You are using Unity iPhone Basic. You are not allowed to remove the Unity splash screen from your game."

For which I found a solution here i.e., by deleting the key UILaunchStoryboardName~iphone from the Custom iOS Target Properties in Info tab.

My question is : How do i do the same for Android. Is there a way to restore the Splash Screen directly in the Unity or do I need to dig into the Android code.

Important : The game after start gets minimised or sometimes crash at launch. And sometimes the graphics & animation are not apprearing as it should be and again it crash eventually.
