I’m sorry, but I looked before I published, and what I asked wasn’t there. As you say with that " nearly ", what it says there is for the component Splash, does not approximate what I’m asking …
That’s what happened to using the Splash Screen. What I asked is the switch between screens, which Mika answered me well. Thanks Mika!
Aren’t they similar? When app opens, it showing screen1 (with or without splash image). It comes with white screen. When you switch screens, the app opens another screen and closes current one. It also comes with white screen.
To summarize, opening a new screen on Android always happening after a white or gray/black screen.
