What should I know in order to write apps?

[mbit]

Hi,
So all I know at the moment is to download apps from the market.
But I want to know how to write my own app.... So what's should I know ? SQL, Java ? Something else ?
Thank you.

Java, xml sql i guess occasionally but not really needed for all apps java is the main one you need. Eclipse has a nice android plugin that helps a lot so i recommend you get that as well

"Hello Android" and "Hello World" would be a good start if you don't already know. The are tutorial/introduction books. I downloaded .pdf's off the web but hard copies aren't that expensive. Its just a pain with pdf's if you're not working on dual screens. Hope this helps get you going.
