I am new to this forum and in using the MIT App Inventor. I gave it a try and it looks great. Now I tried to change the default icon with mine but the inventor was unable to build my project app with the following message:
App Inventor is unable to compile this project.
The compiler error output was
________Preparing application icon
Is there any other way of changing the icon or if there is a recommended icon size and type (.ico, .png, etc) ?
