Android Question Creating Library - Unexpected Top-Level Exception

[Anirban Sen]

I was trying to follow Youtube tutorial on B4A library creation.

I think I followed the instructions properly but I am getting unexpected top-level exception. Screen shots are attached for reference.

Kindly help in pointing out on what I am doing wrong.

You are probably using the wrong version of Java. I recommend you to use SLC to compile the library.
