Explanation
Based on the above code, apparently you're using the main thread to perform I/O operations. Main thread are generally used for user interface operations. It's better to use background threads for I/O operations. - They are more efficient.
Here's demo app which I created to demonstrate use of JSoup with MVVM architecture.

Quick Solution
class MainActivity : ComponentActivity() {
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
setContent {
// Initiate Coroutine scope
val scope = rememberCoroutineScope()
var text by remember {
mutableStateOf("")
}
JsoupTheme {
// A surface container using the 'background' color from the theme
Surface(
modifier = Modifier.fillMaxSize(),
color = MaterialTheme.colors.background
) {
// Initiate coroutine scope will will run on IO thread & write method to get the text from the website
scope.launch(Dispatchers.IO) {
val url = "https://en.wikipedia.org/wiki/Steve_Jobs"
Jsoup.connect(url).get().also {
text = it.text()
}
}
// Fetch result from the state variable [Text]
Text(text = "Result: $text")
}
}
}
}
}
