USB host shield-Android

Hi everyone,

So I have an Arduino UNO SMD and an USB Host Shield and I want to try the USB Host shield 2.0 Library.I uploaded to my arduino the ArduinoblinkLED of this library using the arduino IDE and the android app using Android Studio.

But when I connect my Arduino to the Android tablet(ASUS Kool 4.2.2) , It says "Connected as a media device" instead of opening the app as it should.

Do you guys no what is the problem ?

Thanks in advance,
