createPrintDocumentAdapter replacement

Question

I get a warning when building my android project that "createPrintDocumentAdapter" has been deprecated. It is a method on WebView.

I have been looking but have been unable to find what the intended replacement is. Can anyone shed some light on this?

Thanks, Jason

Answer 1

Per the Javadoc for createPrintDocumentAdapter():

This method was deprecated in API level 21.

Use createPrintDocumentAdapter(String) which requires user to provide a print document name.

Therefore if you need to support < API 21, continue to use the current method, but on API 21+ devices, use createPrintDocumentAdapter(String)

Answer 2

Based on the accepted answer and the official example:

@SuppressWarnings("deprecation")
private static void createWebPrintJob(Context context, WebView webView) {

    // Get a PrintManager instance
    PrintManager printManager = (PrintManager) context.getSystemService(Context.PRINT_SERVICE);

    String jobName = context.getString(R.string.app_name) + " Document";

    // Get a print adapter instance
    PrintDocumentAdapter printAdapter;
    if (android.os.Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
        printAdapter = webView.createPrintDocumentAdapter(jobName);
    }
    else {
        printAdapter = webView.createPrintDocumentAdapter();
    }

    // Create a print job with name and adapter instance

    PrintJob printJob = printManager.print(jobName, printAdapter,
            new PrintAttributes.Builder().build());

    // Save the job object for later status checking
    mPrintJobs.add(printJob);

}
