PDF Reader/ Viewer App

I need to develop an app where it will download PDF files from the server and open it within the app. It is asked not to use external PDF reader/viewer to read the PDF.

Is there any sample project available where i can find the PDF reader? what approach should i follow to develop the app here?

I have not start codding, but will use the latest version of the framework.

Achei algo chamado document viewer, da uma olhada e vê se atende a sua necessidade
