I want to develop an application which works both in a regular browser and as an Android app. Both seem suitable but would I be right in saying if I went with Phone Gap, deploying the same html content as a regular, server hosted website is not trivial and would require modification? Also, are multi page applications not desirable in a Phone Gap wrapper? 

Are there any alternatives I should consider? I'm surprised someone hasn't already written an Android wrapper with all the hardware access wiring done already. Or have they?
