This means something about your app was not correctly uninstalled. This steps help to force uninstall from internal commands:

1. Connect your phone to PC with usb
2. From your shell launch:

    $ adb shell
    shell@android:/ $ su
    shell@android:/ # pm list packages | grep <part of package>
    package:com.android.providers.applications
    package:com.android.providers.calendar
    package:com.android.providers.contacts
    package:com.android.providers.downloads
    ...
    shell@android:/ # pm uninstall <package>
    shell@android:/ # exit
    shell@android:/ $ exit
    $

Basically, you log into android shell, become superuser, find problematic packages, and uninstall it

The solution for me was to select the "Build > Clean Project" menu option. It took a long time but the application deployed once it was complete.
