Hi,

I am trying to display the .pdf file in my application, In other threads I read thru webview we can do it, so I tried like..

B4X: 
WebViewDisplay.LoadHtml("<html><body><img src='file:///android_asset/filename.pdf'/></body></html>")

but it is showing a small icon with "?" .. could not able to find what is wrong here ?! inside html tag I tried "file" instead of "img", still not worked.

help me to find what is missing here .. or suggest me the best way to display the pdf file.

Thanks,:sign0085:

Thanks kanaida,

I included the OpenPdf function and phone library in my code, and copied the file in application .apk path, and as well as in files tab thru "add files".

when I open the application is asks "Choose PDF Viewer" .. after choosing pdf viewer its shows "The document could not be opened" , could someone tell me what is the problem here ?

PS:- tested in emulator and device after installing adobe reader app.

Thanks Erel, could you tell me what is the value for folder ?

I copied pdf file in "D:\projects\myapplicationfoldername\files\filename.pdf", I tried different combinations for folder input, but nothing works.

I am getting "The document path is not valid." Error.

Do not use Windows file and folder naming convention. Here is an example of a pdf file located on the root of the SD card.
B4X: 
Dim folder   As String         :folder=File.DirRootExternal    'root of SD card on device
Dim filename As String         :filename="Kumar.pdf"   'this is the file name
OpenPDF("file://" & File.Combine(folder, filename))

I tried this, and earlier tried like..
B4X: 
OpenPDF("file://" & File.Combine(file.DirRootExternal, "filename.pdf"))

still getting the same error.

where should I copy the file ? or just adding the file into the files directory is enough ?

Do not put the file in a folder called:files. Simply copy the file from your PC if it is called: filename.pdf to the main folder of the SD memory card.

Hi Erel,

As you suggested, Copied the file from dirassets to sd card folder, like..

B4X: 
File.Copy(File.DirAssets, "Manual.pdf", File.DirDefaultExternal, "Manual.pdf")
OpenPDF("file://" & File.Combine(File.DirDefaultExternal, "Manual.pdf"))

now its working fine. Thanks.

That's the package name for IceFairy's pdf viewer library.
Actually it's the package name for the native java library that IceFairy's library wraps.
There's three files required for IceFairy's library:
  • b4aPdfViewer.jar
  • b4aPdfViewer.xml
  • PdfViewer.jar

PdfViewer.jar contains the cx.hell.android.lib.pagesview.PagesView class that is missing.

@gwapong Do you have all three of these files in your b4a additional libraries folder?

Martin.

The emulator cannot access Windows file system.
You can embed the file inside the APK by adding it in the Files tab. It is then accessed with File.DirAssets.
The pdf reader will not be able to read an internal file. You will need to first copy the file from the assets folder to the storage card.

Sorry to continue this old thread.

I can not open a file in the directory of my application?

Are there any accessible directory to save the PDF and the adobe reader that can show?

Is it absolutely necessary to keep the PDF at sdcard?
