72/5000 Configuration of web view application or recommendation of some company.

I bought this app
Https://codecanyon.net/item/universal-webview-android-app-push-notification-admob-inapp-billing/18033758 and the one in the IOS version https://codecanyon.net/item/universal-webview-ios- App-push-notification-swift-admob-inapp-purchase / 17383449.

However I have no ability to configure them, although it is something simple and with tutorial, but my computer every time I try to install the android program it hangs.

So I decided to ask for help getting their configuration or some similar service indication of the web view app.
