Every time I click a button, my app closes. This only started happening after I put the code I was executing inside the onclick event. Before that it was just a toast, and that worked fine.
I can't make heads or tails from the debug output:

When I started the app with just the button and the textview it worked fine displaying the toast.
As soon as I add the jsoup code to scrape a website it force closes when I click the button. I have debugged but I get nothing, and looking up the error, the only thing I could see was some where told to add finish().
It still happens so I figured I would ask people who would know.
I have done the project in Android Studio and had this issue too, but this code I have done using IntelliJ, created a new empty android project.
I know it's probably a stupid error and an easy fix, but this is my first app using jsoup (I tried skrape{it} but there is less documentation available and support.
I have edited the code to include my attempt to catch the error and I have also created the xml file as instructed and The app still just exits when i click the button.
Any other ideas?
Another thing I have just noticed, the app crashes after about 10 secs regardless of where i put the debug point, I barely have time to click step into before it quits.
Does this help shed light on my issue?
@Tenfour04, has correctly point to the error to solve this. Create "xml" folder in "res" folder and create "network_security_config.xml" file
In manifest under application tag, add
Hope this will help you!
