disable notification to connect to a USB Function Filesystem in Android 7.0

We have written an android application that communicates with a piece of custom hardware over USB. Prior to Android 7.0 Nougat when we plugged in the usb the app would lauch automatically and establish a ptp connection between the two devices. Now in Android 7.0 the app no longer launches automatically. Instead a USB symbol appears in the upper left corner. Pulling down the notifications window shows a notification that reads as follows:
Android System
Connected to USB Function Filesystem
Tap to view files
How can we avoid having this permissions notification pop up before starting our app?

Porting Windows Phone 8.1 app to UWP

I'm working on a port of my WP 8.1 app to run on tablets, and PCs. I started working on a Windows 10 port, but I realized that it won't run on Windows Phone 8.1 devices. As far as I know the other way was to create a Universal 8.1 app, but that would mean to redesign most of my pages, there would be a bunch of API and control incompatibility with WP and Windows 8.1. (Pivot control does not exist in Windows 8.1). That's why I chose the easier way to port to UWP. The question is: can I upload a Windows Phone 8.1 package, and a Windows 10 package (only PC and tablet device families targeted) to the same app in dev center? So both mobile and PCs, tablets are supported.
Yes, you can upload (say) a Windows Phone 7 Silverlight package, and a Windows 10 universal package. Devices will get the highest version numbered package that will work for their device
