Android Question Open PDF file

[Zak Petr]

Hi,

I need to open downloaded pdf file, which is saved in File.DirInternal .
I use this code:

    Dim ia As Intent
   
    If File.Exists(File.DirInternal ,"downloaded.pdf") Then
        ia.Initialize(ia.ACTION_VIEW, "content://" & File.Combine(File.DirInternal,"downloaded.pdf" ))
        ia.SetType("application/pdf")
        ia.WrapAsIntentChooser("Choose PDF Viewer")
        StartActivity(ia)
    End If

Dialog for select reader starts properly.
If I select reader, reader starts properly as well.

But each reader tell me, that file is not accessible .

Android Version in Phone is 11 .

Manifest info: <uses-sdk android:minSdkVersion="17" android:targetSdkVersion="28" />


I tried:
- to use File.DirRootExternall or DirExternall - the same problem
- to use file:// instead of "content://" - the same problem

Many thanks for your answers.

android.jar / targetSdkVersion / minSdkVersion

There are several versioned components that affect the compilation process and the runtime behavior of our apps. The purpose of this tutorial is to explain the differences between them and help you choose which version to use. Each Android version is mapped to an api level. You can see this...

You need to use fileProvider
