Build Android App(.apk) problem




Hello, I am new to Mit App Inventor! I've made an app and want to build it in form of Android App(.apk) but there's something wrong while building it. I don't know what's wrong and don"t quite understand what it says. I think there might be problems with one of the screen's block. I'm here to seek for help and guidance since it's an important project.

This is a tough one. The map screen has no errors.

The yail line number does not help track back to a location in the scm or blk files.

I tried renaming the Return button in the map screen to btnReturn, in case it was a keyword.
That was a waste of time.

I do notice a lot of map markers in the Designer, but examination of their Designer properties found nothing fishy.

I was able to build the app on the code server, after deleting the map screen.

I recommend adding a new map screen, with the map markers loaded at run time from a Media folder CSV file (type of recycling center, lat, long).

Do you have those in a file, or do you need help extracting them from the map.scm file in the app aia export?

Thanks for checking so thoroughly! I appreciate your help. I’ll try it out tomorrow.

Thank you so much! I was able to build it after deleting some markers.
