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/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.

Can you install APK from ADB?

ADB (Android Debugging Bridge) can be used to execute commands on your VR device. It's mostly used to install applications (APK files) from a Windows PC or Mac with a device connected with USB.

Can not install APK Android?

Why APK won't install on Android? First, make sure that your Android version supports the APK version you want to install. Also, remove the Play Store version of the app before installing an APK. Don't forget to check the storage space and permission to install apps from unknown sources.

Yes, use the adb install -r switch.

Running adb with no options will give help.
