Hello , i have added the pdfbox for android library with #AdditionalJar:
Code: 
#Region  Project Attributes
    #ApplicationLabel: B4A Example
    #VersionCode: 1
    #VersionName:
    'SupportedOrientations possible values: unspecified, landscape or portrait.
    #SupportedOrientations: portrait
    #CanInstallToExternalStorage: False
    #AdditionalJar: pdfbox-android-2.0.27.0.aar

#End Region

i have this inline java code :
Code: 
Sub Class_Globals
    Private joNative As JavaObject
End Sub

'Initializes the object. You can add parameters to this method if needed.
Public Sub Initialize
    joNative = Me
End Sub

Public Sub FirstMethod As String
    Return joNative.RunMethod("fillForm",Array As String("11/12/1967","1","1",File.Combine(File.DirInternal,"verifica_template.pdf")))
End Sub

See the first thread below in Similar Threads.

pdfbox can not find the Fonts added to the aar.
Solution is to change/rewrite the pdfbox-source and compile it again. You then can add them as resource in your app.

Legacy notice!


iText 5 is the previous major version of iText’s leading PDF SDK. iText 5 is EOL, and is no longer developed, although we still provide support and security fixes.

BTW: iText is not a free PDF-Creation-Library
