nothing too helpful to offer but i was able to export to (google) apk without issue using the latest version.
i also ran a
google search of the forums and found 1 other
thread referencing the error; it was for iOS (and i saw no follow-up) but it leads me to believe the issue might be with a failure to copy the android player into the export.
i'm assuming you're using the latest version and tier 1?
otherwise, sorry i couldnt be more help :/
add: fixed the typo in thread title ("sorce") for future reference/in case we figure out what the issue is
