Thanks for identifying 2 folders as my problem as in the old thread cited. As in the thread I imported to code.appinventer and created the apk, but unlike in the thread, I got the same bad results. As in the old thread my orig app is 6 years older than the "save as" copy which I am trying to update. It seems the dev. environment between old and new versions of the app are not compatible. At this point I shall abandon my attempts to update this old app. thank you all for your help.
