我为Android和iOS开发Unity应用程序。当我在Android Platform→Player settings→Publish Settings上进行Unity构建时，添加密钥库并选择Key Alias。
之后我在Android Studio中打开了Profile or debug APK，当我运行app时出现错误
Installation failed with message INSTALL_PARSE_FAILED_NO_CERTIFICATES: Failed to collect certificates from /data/app/vmdl1775631111.tmp/base.apk: Attempt to get length of null array.
It is possible that this issue is resolved by uninstalling an existing version of the apk if it is present, and then re-installing.
有什么可以帮到我？
