I dont know what I have done but I create an app and test it, it works. When I export it to my pc the acrobat reader is doing something and then I cant even open it. I know its something I have done and I need someone to help me fix it.
You cannot open an AIA or APK file on the PC. You are meant to open the APK file on an Android device to install the app, or import the AIA file into App Inventor.
Thank you for the video! I think I am not understanding what I am supposed to upload. I was able to drag app to the desktop and put it in a folder. I have a cover letter and my app (which maybe I should take screenshots of) and submitted it. I will just keep working reading and trying stuff, I don't want to fail.
Another way to share a project is to add it it to the Gallery.
(Look for the Add to Gallery button to appear when you check your project's check box in the Project list.)
Once you have added your project to the Gallery, you can add documentation to it and share a link to it.
