title: Android Market Publishing Multiple apk's
body: <p>I have developed three different versions(as different projects) of an app(large,normal,small). How can I upload them as a single app with multiple apk's. Do I need to change package names? How about Keystore? Do I need to use same keystore or different keystores for different versions. And what about version number? Do the names of apk's matter?</p>
