In B4A you could use the below intent to view a PDF file. Would be nice to have the same functionality in B4i

Dim i As Intent 'Requires a reference to the Phone library
i.Initialize(i.ACTION_VIEW, "file://" & File.Combine(File.DirRootExternal , "data.pdf"))
i.SetType("application/pdf")
i.WrapAsIntentChooser("Choose PDF Viewer")
StartActivity(i)
Activity.Finish

Thanks,
Johan

If intents don't work for iOS, perhaps the xCode functionality webview loaddata can do the job :

Have you tried to just load the pdf to the WebView? I expect it to work:

B4X:

WebView1.LoadUrl("file://" & File.Combine(File.DirAssets, "yourpdf.pdf"))

This is a b4a project. Please start a new thread for this in the Android forum.

Erel,

We have the same issue. Our quirk is that it works great in debug but not in release. This is b4i, whether 1.x or 2.0. Any thoughts? Here is a file with the pertinent code.

Can you upload a small project that demonstrates the issue (File - Export as zip)?

Sorry, should have thought about doing that. Here it is. Running in debug works, but not in release.

Thanks,
Tm

I see it too. Seems like WebView doesn't open the pdf file if it is in the assets folder. You will need to copy it to File.DirTemp before you open it.
