lauchUri("file://<path to Pdf file>") not opening device default PDF reader

So I’ve been able to download a PDF file to device, and I want to open the file using InterApp.launchUri(“file://”);

but, the app crashes when this method is called on ANDROID

I have a pdf reader installed on the device


so, looking at LogCat, android.os.FileUriExposedException is thrown when this call is made, any help getting around this, without going into Uno
