In your activity, add this two properties:

ReaderController m_vPDF = null;
Com.Radaee.Pdf.Document doc = new Com.Radaee.Pdf.Document();

Then OnCreate, add this:

Global.Init((Android.App.Activity)Context);

Global.ActiveStandard ((Android.App.Activity)Context, "Company", "Email","key");

m_vPDF = new ReaderController(Context);
doc.Close ();

// PCLstorage to get app files folder
// you can use you own implementation here to get filepath
var rootFolder = FileSystem.Current.LocalStorage.Path;
var path = System.IO.Path.Combine (rootFolder, "filename");

int ret = doc.Open( path, null);

switch (ret)
{
    case -1://need input password
        break;
    case -2://unknown encryption
        break;
    case -3://damaged or invalid format
        break;
    case -10://access denied or invalid file path
        break;
    case 0://succeeded, and continue
        break;
    default://unknown error
        break;
}

m_vPDF.Open(doc);

var layout = new LinearLayout(this);
layout.Orientation = Orientation.Vertical;

layout.AddView(m_vPDF);

SetContentView(layout);

Then on Dispose:

if (m_vPDF != null)
{
    m_vPDF.Close ();
    m_vPDF = null;
}

if (doc != null) {
    doc.Close ();
    doc = null;
}

Global.RemoveTmp ();

This was a long time ago so, maybe radaee library has changed a lot. Cant find example of the other one.

If you want to go with something more modern, take a look at this:

https://developer.xamarin.com/recipes/cross-platform/xamarin-forms/controls/display-pdf/

You can implement the same thing in a native WebView.

[alexrainman]

They use a custom renderer with each platform native WebView, so, if you follow this link, you will see how Xamarin Android do the thing:

This link shows you how to do it in Android:
