Android Question Compilation error

[Eduardo Pajaro]

Greetings to all.
I'm new to this, I worked well with B4A trial, but now I have the license and when I compile it generates the following error attached file.

I thought it was the JDK, I deleted it and reinstalled it, but the same error remains.

They would be so kind and help me, would you thank them?

I removed the DSK and reinstalled it and now IF it lets me compile !!!

This error means that you have used an old version of android.jar (under Tools - Configure Paths).
