        Dim outs As OutputStream = File.OpenOutput(File.DirInternal, argfilename, False)

Why are you requesting external storage write permission and then writing your data to File.DirInternal?

I want to create a pdf file from an url. The url contains image and barcode. The url could be sent to printer then print or save as pdf without problem.

But I want to create pdf without showing the printer screen. I tried the following but always got blank pdf. Any hints?

B4X:

    wv_pdf.LoadUrl(argurl)
    Wait For wv_pdf_PageFinished (Url As String)

    Dim lpdf As PdfDocument
    lpdf.Initialize
    lpdf.StartPage(595,842) ' a4

    Dim lbmp As Bitmap
    lbmp = wv_pdf.CaptureBitmap
    Dim lrect As Rect
    lrect.Initialize(0,0,595,842)
    lpdf.Canvas.DrawBitmap(lbmp, lrect, lrect)
    lpdf.FinishPage
 
    gRp.CheckAndRequest(gRp.PERMISSION_WRITE_EXTERNAL_STORAGE)
    Wait For Activity_PermissionResult (Permission As String, result As Boolean)
    If result Then
        Dim outs As OutputStream = File.OpenOutput(File.DirInternal, argfilename, False)
        lpdf.WriteToStream(outs)
        outs.Close
    End If
    lpdf.Close

You are right. I should use file.DirDefaultExternal.
