the error I'm pointing out is
[GenerateClasses] ERROR: Compile R Classes returned E=1
[GenerateClasses] ERROR: Could not compile R classes
[GenerateClasses] Task errored in 0.288 seconds
.

That's the first time we have seen that error.

Could you export and post your .aia file for further examination?

Removing extra dots from the file name and compiling on code.appinventor.mit.edu worked for me.
