Thanks, checked:

    Dim pm As PackageManager 'phone library
    Dim in1 As Intent
    in1.Initialize("android.nfc.action.TECH_DISCOVERED", "")
    For Each s As String In pm.QueryIntentActivities(in1)
        Log(s)
    Next

Result:

pm.QueryIntentActivities(in1).size=0

Try this code (from post #3 in the first link I posted) and see if it lists any apps, if it does, then it should be able to open a PDF file:

Dim pm As PackageManager
Dim Intent1 As Intent
Intent1.Initialize(Intent1.ACTION_VIEW, "file://")
Intent1.SetType("application/pdf")
For Each cn As String In pm.queryIntentActivities (Intent1)
     Log(cn)
Next
