[MohamedTamer]

Have you updated the app inventor sources to the latest version?

[MohamedTamer]

Also check your package name.

[vknow360]

Are you sure that you have placed java file in src folder?

[Juan_Antonio]

Are you building it with the Extension Template Repository?

Extension Template Repository

Hi all, I have been experimenting on a new system for building extensions. This version no longer requires checking out the whole source tree of App Inventor to build an extension, which means that you can manage extensions in different repositories without a lot of overhead. The template repository is available on GitHub. I would appreciate feedback on this approach and how it is or isn’t working. Regards, Evan W. Patton, Ph.D. Lead Software Engineer, MIT App Inventor

[MohamedTamer]

Can someone try to compile an old extension?Because it isn't even working with me too .I'm using the app inventor sources.And i've placed the java file in the src folder and checked that i have the latest version.

[kangris]

dont forget set annotation @SimpleObject(external = true)

[MohamedTamer]

i've add it of course

[MohamedTamer]

Just wanted to confirm.this problem has nothing with the app-inventor sources.because i got the same log in appybuilder code editor.It was something in my code.

Why was this error?

Because I've accidentally removed the @DesignerComponent annotation at all Btw, thanks @kangris the error was really near from what you told me That happens when you remove when ( or even both as well ) from the two annotation @SimpleObject and @DesignerComponent.You must check this out.
