Javascript to include in my mobile apps (Android)

I need a Javascript for this: - I have some mobile apps. I want a javascript that I can copy paste in my mobile app (Android) very easy. - Now a user will install the app. - If the user go use his mobile browser and go to [login to view URL] the javascipt of the just installed app will see the user is visiting the Amazon site. - Now the background script will add my Amazon affiliate code in the browser. - So the url [login to view URL] will now automatically replaced to [login to view URL] NOTE: If the user is visiting an url like: http://www.amazon.com/s/ref=s9_dnav_gw_ir03_s?__mk_de_DE=%C5M%C5Z%D5%D1&node=327472011,!327473011,342095011&page=1&field-is_prime=183892031&bbn=327473011&pf_rd_m=A3JWKAKR8XB7XF&pf_rd_s=center-5&pf_rd_r=1RXG67Z5PACCRVH38R90&pf_rd_t=101&pf_rd_p=359314667&pf_rd_i=301128 This should be added to the end of the url &tag=myaffiliateid FINAL: I only do business with people with good reputations.
