Ho creato un app molto semplice con due schermi, uno schermo con vari tasti, l'altro visualizza un sito web e funziona tutto bene. poi ho deciso di cambiare la pagina web e non mi compila più l'apk, anche se riapro il vecchio progetto funzionante e installato sul mio smartphone, mi da sempre "App Inventor non è in grado di compilare questo progetto." con una sfilza di errori per me incompressibili.
L’errore di compilazione è
