android - How to get data from html page using java? -
how data xml/html page?
i'd make android app, in users notification of school-lesson fell out. website looks like: http://www.anony.ws/image/pc9
users fill in school class (klas) after installation of app. want pick data table, users should receive notification if it's class. (example:
if ( userclass == klas ), alert ("hey, " + + " " + + "because of" + opmerking); something that. have no idea how should pick data out of table, it's weird page. makes more difficult because page fades (1/2) (2/2) (max 10 listings each page, 50 listings = 5 pages) , find out example here: http://suse.ghlyceum.nl/dagrooster/lwoo/. how should pick data , put them in java vars!
