this is my code

B4X:
Dim FileName As String = "example.csv"
        'copy the shared file to the shared folder
        File.Copy(File.DirAssets, FileName, Starter.Provider.SharedFolder, FileName)
        Dim in As Intent
        in.Initialize(in.ACTION_VIEW, "")
        Starter.Provider.SetFileUriAsIntentData(in, FileName)
        'Type must be set after calling SetFileUriAsIntentData
        in.SetType("image/*")
        StartActivity(in)

Sounds like you did not implement FileProvider correctly into the Manifest-Editor

I added this
XML:
AddManifestText(<uses-permission
   android:name="android.permission.WRITE_EXTERNAL_STORAGE"
   android:maxSdkVersion="18" />
)
AddApplicationText(
  <provider
  android:name="android.support.v4.content.FileProvider"
  android:authorities="$PACKAGE$.provider"
  android:exported="false"
  android:grantUriPermissions="true">
  <meta-data
  android:name="android.support.FILE_PROVIDER_PATHS"
  android:resource="@xml/provider_paths"/>
  </provider>
)
CreateResource(xml, provider_paths,
   <files-path name="name" path="shared" />
)

but now i have this error when application start:
