我使用Unity构建了我的Android手机应用程序。我没有使用eclispe，只有统一。
I keep getting the error message "INSTALL_FAILED_VERSION_DOWNGRADE" when I try to push the android package onto my device.

The app is already installed on device. This installed app has higher versionCode in the AndroidManifest.xml.
该应用已安装在设备上。此安装的应用程序在AndroidManifest.xml中具有更高的versionCode。
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].
示例：如果您尝试将.apk与versionCode =“30”安装在.apk上，并且versionCode =“20”则可以正常运行。如果您尝试使用versionCode =“20”在.apk上安装.apk，而使用versionCode =“21”，则会获得[INSTALL_FAILED_VERSION_DOWNGRADE]。
