Exception while invoking HP ePrint PDF Preview Activity

I am trying to get my android app invoke HP ePrint PDF Preview Activity.

Intent intent = newIntent();
intent.setPackage("com.hp.android.print");intent.setClassName("com.hp.android.print","com.hp.android.print.preview.PdfPreviewActivity");
intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
Uri uri = Uri.parse("http://www.pdf995.com/samples/pdf.pdf");
intent.setDataAndType( uri,"application/pdf");
if(intent.resolveActivity(getPackageManager())!=null)
     getBaseContext().startActivity(intent);

I am getting the below error (taken from Logcat of the device):

HP ePrint works fine when used manually. Any idea about a fix?
