Android Question Open Audio on Android 7

[Multiverse app]

The following code worked on pre Nougat devices:

    Dim musicin As Intent
    musicin.Initialize(File.DirRootExternal&"/Music", "1.mp3")
    musicin.SetType("audio/*")
    StartActivity(musicin)

On Nougat, it returns the following error:
(Exception) java.lang.Exception: android.os.FileUriExposedException: file:///storage/emulated/0/Music/1.mp3 exposed beyond app through Intent.getData()

I tried

But, No luck

I still get a java.lang.reflect.InvocationTargetException error

My code:

Sub OpenAudio
   
    Dim i As Intent
    i.Initialize(i.ACTION_VIEW, "")
    i.SetType("audio/*")
   
    Dim Uris As List
    Uris.Initialize
        Dim u As Uri = CreateFileProviderUri(File.DirRootExternal&"/Music", "1.mp3")
        Uris.Add(u)
    Dim jo As JavaObject = i
    jo.RunMethod("putParcelableArrayListExtra", Array As Object("android.intent.extra.STREAM", Uris))
    i.Flags = 1
   
   
End Sub

Sub CreateFileProviderUri (Dir As String, FileName As String) As Object
    Dim FileProvider As JavaObject
    Dim context As JavaObject
    context.InitializeContext
    FileProvider.InitializeStatic("android.support.v4.content.FileProvider")
    Dim f As JavaObject
    f.InitializeNewInstance("java.io.File", Array(Dir, FileName))
    Return FileProvider.RunMethod("getUriForFile", Array(context, Application.PackageName & ".provider", f)) 'Error occurs here
End Sub

Based on the error message the file does not exist.

What is the output of Log(File.Exist(Dir, Filename)) ?

 

[Multiverse app]

It returns true.
I am sure there is a mistake in my code itself. Not sure where.

 

[Erel]

Does it only happen when there is a space in the file name?

 

[Multiverse app]

No. Returns the error every time. Is my code correct?

 

[Erel]

Run this project as-is: https://www.b4x.com/android/forum/t...ut-fileuriexposedexception.72538/#post-461501

Does it work?

 

[Multiverse app]

Yes, It works fine.

 

[Erel]

You need to compare it to your project and find out why it fails there.
