如题：
Installation failed with message Failed to finalize session : INSTALL_FAILED_INVALID_APK: /data/app/。。。。
It is possible that this issue is resolved by uninstalling an existing version of the apk if it is present, and then re-installing.
WARNING: Uninstalling will remove the application data!
Do you want to uninstall the existing application?
类似以上错误，解决方式：点击build->clean project ,然后再点击 rebuild project。然后部署就过去了。
