why do some java eclipse errors not have a specific line of code?

Question

This error has no line of code within my code that I see. How do I track down where the error is coming from? I found a link here to solve the problem but I just don't even know where to put the code, I have like 10000 classes, finding the problem manually doesn't sound fun.

Answer 1

Globally search your code for places where you're using a webview. Then check the URL you're passing. This error typically occurs when you are passing a URL to the webview without specifying the protocol.

For instance, change:
