Any ideas of how to convert this ValueCallback into suspend? evaluateJavascript needs to be called from the main thread failing to do so throws an exception ( All WebView methods must be called on the same thread. (Expected Looper Looper (main, tid 2) {3acde0b} called on null, FYI main Looper is Looper (main, tid 2) {3acde0b}))

return suspendCoroutine { cont ->
            webView.evaluateJavascript( string ) { result ->
                cont.resume( result )
            }
        }

Have you tried this?:

return withContext(Dispatchers.Main) {
        suspendCoroutine { cont ->
            webView.evaluateJavascript(string) { result ->
                cont.resume(result)
            }
        }
    }

@streetsofboston Thx, that works

From the documentation it is not clear whether the lambda, provided to the suspendCoroutine, is called in the same context that called the suspendCoroutine. But it seems it is indeed called in the same context.

yeah, it is
