Android Question [SOLVED] API 31 Android 13 - crashes when sending intent to view PDF file

[Segga]

I'm using the following code to view PDF files that have saved by the app.
After setting android:targetSdkVersion="31" in the manifest editor, the app crashes when trying to launch the intent on my Android 13 device - Android 12 and below seem to be working fine.

Sub SendToPDFViewer(pdfFile As String)
        File.Copy(Main.sDirSaved, pdfFile, Main.Provider.SharedFolder, pdfFile)
        Dim In As Intent
        In.Initialize(In.ACTION_VIEW, "")
        Main.Provider.SetFileUriAsIntentData(In, pdfFile)
        In.SetComponent("android/com.android.internal.app.ResolverActivity")
        In.SetType("application/pdf")
        StartActivity(In)
End Sub

The error message is as follows:

Remove this line: In.SetComponent("android/com.android.internal.app.ResolverActivity")

#If B4A
Sub OpenPDF(FileName As String)
    
    File.Copy(xui.DefaultFolder, FileName, Main.Provider.SharedFolder, FileName)
    Dim Inte As Intent
    Inte.Initialize(Inte.ACTION_VIEW, "")
    Main.Provider.SetFileUriAsIntentData(Inte, FileName)
    'Type must be set after calling SetFileUriAsIntentData
    Inte.SetType("application/pdf")
    Inte.WrapAsIntentChooser ("")
    StartActivity(Inte)
End Sub
#End If

This is the routine I use.
