Splash screen problem after close the app by double clicking the back button

When I restart the app after I exit the app on android by double clicking the back button, there is no splash screen and icon. I use this statement(“ionic.Platform.exitApp();”) to exit app, and also try using “navigator.app.exitApp();”. But, it do not solve my problem yet.

So, I don’t know how to solve it, please help me.

Thanks a lot!
