Cannot generate .aix files anymore. Why?

[Arne Mailand]

Hi,

I succeeded in creating a test .aix file according to this tutorial a few days ago:

http://ai2.appinventor.mit.edu/reference/other/extensions.html

I could generate the AltCamera.aix extension with terminal (os x) and ant etc. The directory "extension" was created, which included that AltCamera.aix file.

But as of today, I cannot create any .aix files anymore. I repeated the same procedure, but no extension directory or AltCamera.aix file is coming up. The @SimpleObject(external = true) line is set also.

In terminal, I get this output below. Can anybody help me out?

Thanks

Well, the errors seem to be happening in line 36, 343 and 230. Unfortunately, I am pretty unsure how the lines are numberd. Can anybody tell me this? I attached the .xml file to this message.

Thanks,

[Arne Mailand]

Hm this is very confusing though, since the xml file does seem to have 150 or 180 lines only (depending on whether you count the comment lines or not). Any ideas?

[Arne Mailand]

By the way, I didnt build the App Inventer on my pc. I skipped that step. Could this somehow be related to the issue? I few days ago, it was no problem though. Should I redownload the whole App Inventer Sources maybe?

[Jos Flores]

It seems like you are using a java.lang.Void type somewhere in your
extension, and the compiler does not like that.

Did you have an issue recently with void and constructors?

cheers,
José

Hey, thanks for your response, José!

Yes indeed I had one :) That was the last extension I tried to compile. But I put changed the parameter in the from

@SimpleObject(external = true)

to

@SimpleObject(external = false)

So I thought this one wouldnt matter anymore and shouldnt affect the build process of test .aix from the tutorial where (external = true) is set. But I was wrong with it apparently. So I removed that file completely from the directory and everything works fine.

Anyways, my goal is to make the extension, which caused the build errors with that void, working. If you are familiar with that, I would be very pleased if you could join the discussion about this in this thread:

https://groups.google.com/forum/#!topic/app-inventor-open-source-dev/y4HemYOYtjk

You might have discovered it aleady.

Thank you a lot
