Unable to change the icon of the app with mine

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) ? Thank you

Why,App Inventor is unable to compile this project. Stuck at "Preparing application icon"
