hi so sorry im a noob in this so maybe this will sound silly for you
so guys im trying to improve firebase extension by adding some blocks to it for personal use
i took it’s source from app inventor source
the problem is that whenever i tried to build it it doesn’t build at all
then i tried the original code without any change and the same thing happened it says couldn’t find a symbol
i don’t understand what i have to do should i start it from the zero ?
could you guide me please
anyone ? ,n
You need to provide the build error in order for us to help you
here is it

The output says syntax error, so please read the output and correct the mistakes. We cannot help you if you don't provide the relevant code snippets
This output says build successfull, please check the out directory
Ant cannot find the classes, try importing
com.google.appinventor.components.runtime.AndroidNonvisibleComponent and com.google.appinventor.components.runtime.Component
yeah it says so but it didn't no file exported nothing there
here wwhen i added them with some other classes it gives me same result as the second case successful build but no aix file
And there’s this test code
