how can i download and store data in an android app?

how can i download and store data in an android app?

i'm new to android! and i want to write a flash card app that has the
ability of shopping. so far i'v faced these problems:
how can i download a file from a service or an url?
how should i transfer my data that includes audio,images and text(buying
flashcards)? i mean what format of data should i use? for example can i
zip my data on the server and extract it inside my app and use the data or
is it a better way?
is there a specific method of client/server authentication (log in)?!so
stupid question...
the last but not least : maybe it would be better to change the question
to how can i write this program?!!!what are the things that i need to
learn?!!
i know my questions are general but as i said i'm newbe so help me find a
good view of what i am doing:D
feel so dumb for asking this question
