Unity android build error: INSTALL_FAILED_VERSION_DOWNGRADE

I built my android Phone app using Unity. I didn't use eclispe, only unity.

I keep getting the error message "INSTALL_FAILED_VERSION_DOWNGRADE" when I try to push the android package onto my device.

I cannot find out what is wrong. Help me please.

The app is already installed on device. This installed app has higher versionCode in the AndroidManifest.xml.

Example: If you try to install .apk with versionCode="30" over .apk with versionCode="20" everyhing is fine. If you try to install .apk with versionCode="20" over .apk with versionCode="21" you get [INSTALL_FAILED_VERSION_DOWNGRADE].
