Delete that folder and test your apk file, is it still there?

@Naannncccyy

Well, look at the package name of your app... actually I do not know, why anyone would want to hide that...

@Naannncccyy

how can generally prevent any one from get the source code

You can't get the source code from an apk file

@Naannncccyy

what is obufstcated text

Check the documentation MIT App Inventor Text Blocks
