How can I know if the PDFViewer is not null? Like for example, You may know that ImageView is not null by getDrawable() method from ImageView.java class.

I tried the getCurrentPage() and getDocumentMeta() in PDFView.java class to check if the PDFViewer is not null but it always crashes on the 12th Page.
