Compiler error on bare project with self-made extension

Hi guys,

when building an app with a self-built extension i get the following:

I see older posts where the compiler output is more verbose. Has this been truncated and no longer as verbose, or is it the nature of the error that has such a short output.
And if truncated. is there an option to make it more verbose? i would like the have the compiler errors to find the error in my extension.

Also i checked for nested project (project within a project) as that came up a lot while researching the current output, but no cigar.... that is not the case here.

That's all you get with "unable" to compile.

For starters, remove the underscores from the project name.

"bare project" ? - put at least a button or a label in it.

For more help, provide the aia.

Well, it's not completely bare. There is a button and a status text display.
Keys and data made random for security purposes.

It runs on app companion, but the tags aren't detected; so my gut says that the reason it doesn't compile is probably the reason the tags aren't detected.

I'm including my aia file (i tried removing the underscores)

mifarefasttest3.aia (17.2 KB)

thnx in advance

Hmmm, some issue with extension, compiles without it.

Did you build it with FAST ?

Yes sir.

I tried with the template first using an app inventor build. But i think maybe that didn't work out so well, the app inventor build, because i would get errors from not recognizing some symbols.

i could retry building it, because i think that might be the only way to get debugging information during compilation. FAST successfully builds and shows no errors, but maybe it has a few shortcuts that misses the problem.

or does the appinventor-sources not contain packages for android.app; android.content; android.nfc; android.util; etc?
