Wrap website as mobile app

I want to wrap my website into an Android app. I will be distributing the APK file myself to various app stores. It needs to have a splash screen, push function using OneSignal and Analytics using Appsflyer. The app will need a connection lost page as well as a native "loading" page when the browser URL changes to a new page. Use any site’s URL and dummy graphics – I will need a central place to edit this. I will need the source code as well as the APK.
