I guess it depends on what you mean by "Web App." If you are talking about a purely Web-driven application that the user gets to by browsing to your website in Chrome or another browser, then you don't need to do anything special for Android.
I suspect, however, that you are talking about an Android app where most of the logic is in Javascript running in a WebView. In this case, you must have an Activity that created the WebView. This Activity is the logical place to initiate in-app billing. You can't call the in-app billing API directly from Javascript, but you can write a Java method to do it and then inject that Java method into your Javascript using WebView.addJavascriptInterface<http://developer.android.com/reference/android/webkit/WebView.html#addJavascriptInterface(java.lang.Object, java.lang.String)>.
