Unresolved reference: createPrintDocumentAdapter (Kotlin + Android)
Question
I'm trying to implement the code from this link using kotlin , but when I try to use any method of the webView I get errors:
Error:(238, 17) Unresolved reference: webViewClient Error:(265, 43) Unresolved reference: PRINT_SERVICE Error:(268, 36) Unresolved reference: createPrintDocumentAdapter
The strange thing is if I comment out the code and while running the app I use the evaluate expression I can create the adapter instance.
Has anyone any Idea?
I also can't access methods from the webView , like webView.webViewClient
Here is the kotlin version of the java code in the link above
private fun doWebViewPrint() {
// Create a WebView object specifically for printing
val webView = WebView(this)
webView.webViewClient = object : WebViewClient() {
override fun shouldOverrideUrlLoading(view: WebView, url: String): Boolean {
return false
}
override fun onPageFinished(view: WebView, url: String) {
createWebPrintJob(view)
}
}
// Generate an HTML document on the fly:
val htmlDocument = "<html><body><h1>Test Content</h1><p>Testing, " + "testing, testing...</p></body></html>"
webView.loadDataWithBaseURL(null, htmlDocument, "text/HTML", "UTF-8", null)
}
private fun createWebPrintJob(webView: WebView) {
// Get a PrintManager instance
val printManager = this
.getSystemService(Context.PRINT_SERVICE) as PrintManager
// Get a print adapter instance
val printAdapter = webView.createPrintDocumentAdapter("document")
// Create a print job with name and adapter instance
val jobName = getString(R.string.app_name) + " Document"
val printJob = printManager.print(jobName, printAdapter,
PrintAttributes.Builder().build())
}

I found that the problem is probably due to a bug in the anko library, when I removed the anko-appcompat-v7-coroutines the code worked
// Anko Layouts
compile "org.jetbrains.anko:anko-sdk25:$anko_version" // sdk15, sdk19, sdk21, sdk23 are also available
compile "org.jetbrains.anko:anko-appcompat-v7:$anko_version"
// Coroutine listeners for Anko Layouts
compile "org.jetbrains.anko:anko-sdk2-coroutines:$anko_version"
compile "org.jetbrains.anko:anko-appcompat-v7-coroutines:$anko_version"
My anko version was ext.anko_version = '0.10.0' since I wans't using anko just yet I opted to remove it and things started to work as expected.
