Finally My App Is Published to Play Store

Hi Guys,
With the help of you guys I just published my app to play store (Fortnite Assistant). If You guys check on my app and find out bugs in the app it will be appreciable. I checked my app recently with 2 devices and it crashes sometimes because I’m using 2 screens. I am already working on it to fix the issue.

P.S: Another Screen only opens when You click on “Fortnite Assistant” Button.
