Android Question File provider error

[andyp]

Hi

Using FileProvider
https://www.b4x.com/android/forum/threads/class-fileprovider-share-files.97865/#content

The example app works no problem.

I have used the code (and manifest, b4a.png file, etc) in my app.

I get this error log:

Error occurred on line: 34 (FileProvider)

Line 34 is:

Return fp.RunMethod("getUriForFile", Array(context, Application.PackageName & ".provider", f))

Thoughts? Thank you.....

If I make this change it appears to work, so the SharedFolder is the same all SdkVersions

But this does not seem right? Why does the example app work with the original code, and my app does not?

Thank you for any help!

Public Sub Initialize
    Dim p As Phone
    If p.SdkVersion >= 24 Or File.ExternalWritable = False Then
        UseFileProvider = True
' add this line: 
        SharedFolder = rp.GetSafeDirDefaultExternal("shared")
' remove these two lines:
'        SharedFolder = File.Combine(File.DirInternal, "shared")
'        File.MakeDir("", SharedFolder)
    Else
        UseFileProvider = False
        SharedFolder = rp.GetSafeDirDefaultExternal("shared")
    End If
    Log($"Using FileProvider? ${UseFileProvider}"$)
End Sub

Don't make any changes to the code. You will break it.

You probably missed the manifest editor code.

Humm… I have checked the manifest - I think I covered everything?

'This code will be applied to the manifest file during compilation.
'You do not need to modify it in most cases. change target 18 to 26

Found the problem - it was with the manifest - I missed:

CreateResource(xml, provider_paths,
   <files-path name="name" path="shared" />
)

Thanks for pointing me in the right direction!!
