Android, Webview, Java, HTML Parsing, SQLite

I have an Android application which opens web site ([login to view URL]) in webview component. Initial page is the login page with capctha and after validation second page shows a report. Spam Protection Password is RedPill. What I want is to replace login page's CSS with my own to make it look like different login page (JOB-A). Then extract report data from web page and save its to SQLite DB (JOB-B). Report have master and detail areas. Master table includes 5-6 fields (name, surname etc.) and detail table includes 7-8 fields (year, month, total days, total amount etc.) I will send video file which shows both Android App and Web page and report page to extract. Please include Spam Protection Password within your message. Otherwise your message will be ignored.
