You are missing the closing-curly bracket(s) } somewhere.

It like you're missing the basics of programming. I recommend you to use a java code editor. Search for the errors in google and in the community once next time.

All the lines or end of the instructions in Java is with ;

For example:

import com.test.add

What you're doing , which correctly, should be:

import com.test.add;

Meulencv · March 7, 2021, 6:14pm

oh, that's right, it slipped my mind , thank you very much.

I don't find the resolution of the errors on the internet

Your code have two errors:

you haven't declared and initialized activity
there is no myEvent method in your code

You should use a Java IDE.

This can be done with AI2 Blocks, just join view-source: before the http part?

Salman_Dev · March 8, 2021, 11:52am

this can do the same thing too, so I think we don't need an extension for that @Meulencv

blocks (3)

Still, it's okay for learning

Meulencv · March 8, 2021, 4:15pm

But I ned to do this, to later do the extension more complex, for example a extension that gives the bitcoin price.

Hello,
I would be very grateful if you could fix my code, thank you very much

Anonymous · March 8, 2021, 5:44pm

@Meulencv did you fixed that?

I have the demo extension code which works.
