Can you repeatedly deploy an APK with 'adb install' without uninstalling first?

Since I'm really not a fan of Eclipse I'm developing my Android app by following the rules listed here: http://developer.android.com开发者_如何学编程/guide/developing/other-ide.html

When I'm deploying with the 'adb install' command I have to manually uninstall the APK from the emulator every time or else the install won't work. Is there any way to bypass this? It's fairly annoying having to add this step in every time.

Yes, use the adb install -r switch.

Running adb with no options will give help.
